Mendelian inheritance (or Mendelian genetics or Mendelism) is a set of primary tenets relating to the transmission of hereditary characteristics from parent organisms to their children; it underlies much of genetics. The tenets were initially derived from the work of Gregor Mendel published in 1865 and 1866, which was “re-discovered” in 1900; they were initially very controversial, but they soon became the core of classical genetics.
The laws of inheritance were derived by Gregor Mendel, a 19th century monk conducting hybridization experiments in garden peas (Pisum sativum). Between 1856 and 1863, he cultivated and tested some 28,000 pea plants. From these experiments, he deduced two generalizations that later became known as Mendel’s Laws of Heredity or Mendelian inheritance. He described these laws in a two part paper, “Experiments on Plant Hybridization”, which was published in 1866.
Mendel discovered that by crossing true-breeding white flower and true-breeding purple flower plants, the result was a hybrid offspring. Rather than being a mix of the two colors, the offspring was purple flowered. He then conceived the idea of heredity units, which he called “factors”, one of which is a recessive characteristic and the other dominant. Mendel said that factors, later called genes, normally occur in pairs in ordinary body cells, yet segregate during the formation of sex cells. Each member of the pair becomes part of the separate sex cell. The dominant gene, such as the purple flower in Mendel’s plants, will hide the recessive gene, the white flower. After Mendel self-fertilized the F1 generation and obtained an F2 generation with a 3:1 ratio, he correctly theorized that genes can be paired in three different ways for each trait: AA, aa, and Aa. The capital A represents the dominant factor while the lowercase a represents the recessive.
The answer options (statements) which best describes the law of segregation are: 2 and 3.
Gregor Mendel was a botanist born on the 20th of July, 1822 in Austria.
Mendel's experiment and findings on pea plants are the foundation on which the modern study of genetics is built upon and as such he his famously regarded as the father of genetics.
One of the laws in genetics, which was derived from Mendel's conclusions in the pea plant experiment is the law of segregation.
The law of segregation is a law which states that the two members of a pair of alleles (diploid) separate during gamete production.
Additionally, the law of segregation states that two copies of each gene segregate or separate in order to ensure that each gamete receives only one allele during its development.
In conclusion, the following statements describes the law of segregation:
All the gametes produced by living organisms with matching alleles for a given trait will have the same allele for that trait. If different alleles are present for a given trait in the body cells of a living organism; the dominant allele will receive half of its gametes while the other half will receive the recessive allele.Read more: https://brainly.com/question/23067535?referrer=searchResults

What is the Purpose of the "DNA extraction liquid"?
Answers
Answer:
plase bear with me i know this is a long answer
Explanation:
The purpose of DNA extraction liquid is to break open cells and dissolve cellular membranes, proteins, and other cellular components in order to release DNA from the cell. This is an essential step in DNA extraction procedures, as DNA is tightly packed within the cell and needs to be isolated and purified for further analysis.
There are many different types of DNA extraction liquids that can be used depending on the type of sample and the downstream application. Commonly used extraction liquids include phenol-chloroform, ethanol, and various commercial kits that utilize a variety of chemical agents and protocols.
The DNA extraction liquid typically contains a combination of reagents that help to disrupt the cell membrane and denature cellular proteins, allowing the DNA to be released and separated from other cellular components. These reagents can include detergents, salts, enzymes, and organic solvents. After the DNA has been released from the cell, it can be further purified using various methods, such as precipitation or column-based purification, depending on the specific application.
In summary, the purpose of DNA extraction liquid is to break open cells and release the DNA for further analysis. It is a critical step in many molecular biology and biotechnology applications, including genetic research, diagnosis of genetic diseases, and forensic analysis.

In taxonomy, what is true about the hierarchal rank of family?
Answers
In taxonomy, true about the hierarchal rank of a family is "A family will usually include far more taxa than a genus".
In taxonomy, the rank of a genus is lower than that of the family. A family is made up of many different genera all working together. Therefore, there are more organisms in a family than there are in a genus. A family is more welcoming to new members than a genus, while a genus is more selective than a family.
In most cases, members of the same family share personality traits. They cannot be distinguished from one another on the basis of the presence or absence of a nucleus. It cannot be that some species have nuclei while others have not.

Which of the following correctly describes the relationship between an enzyme and its function? A. adenylyl cyclase: conversion of CAMP to AMP
B. phosphatase: removal of a phosphate group
C. glycogen phosphorylase: synthesis of glycogen
D. kinase: addition of a tyrosine
Answers
The correct description of the relationship between an enzyme and its function is option B, phosphatase: removal of a phosphate group.
Enzymes are biological catalysts that facilitate chemical reactions in living organisms. Each enzyme has a specific function based on its structure and the reaction it catalyzes. Option B correctly describes the relationship between the enzyme and its function. A phosphatase is an enzyme that removes a phosphate group from a molecule. Phosphatases play a crucial role in cellular signaling and metabolic pathways by regulating the addition and removal of phosphate groups. The removal of a phosphate group by a phosphatase enzyme can have significant effects on the activity and function of the target molecule, such as protein deactivation or modulation of enzyme activity. In contrast, options A, C, and D do not accurately represent the relationship between the enzyme and its function. Option A describes adenylyl cyclase as converting CAMP to AMP, which is incorrect. Option C suggests glycogen phosphorylase is involved in glycogen synthesis, while it is actually responsible for glycogen breakdown. Option D associates kinase with the addition of a tyrosine, whereas kinases are generally involved in the transfer of phosphate groups, not specific to tyrosine.

base pairing occurs between adjacent nucleotides within a single strand of dna. (True or False)
Answers
The statement "base pairing does not occur between adjacent nucleotides within a single strand of DNA." is False. Base pairing occurs between complementary nucleotides on opposing strands of the DNA double helix.
What is base pairing?Base pairing refers to the specific binding between the complementary bases adenine (A) and thymine (T) or guanine (G) and cytosine (C) in DNA. Adenine pairs with thymine (A-T), and guanine pairs with cytosine (G-C).
In a DNA molecule, the two strands are antiparallel, running in opposite directions. The 5′ end of one strand corresponds to the 3′ end of the other, and vice versa. The two strands are held together by hydrogen bonds between the complementary nucleotides. These hydrogen bonds are relatively weak and may be broken during DNA replication and transcription.In conclusion, base pairing does not occur between adjacent nucleotides within a single strand of DNA. Base pairing occurs between complementary nucleotides on opposing strands of the DNA double helix.

These proteins shaped the structure of organisms so we can say that difference in traits occur due to difference in their proteins.
in animal cells, ____ is (are) usually a one-way path.
Answers
In animal cells, the transport of molecules across the plasma membrane is usually a one-way path. The plasma membrane of an animal cell is selectively permeable, which means it only allows certain molecules to pass through it. This ensures that the internal environment of the cell remains stable and does not fluctuate with the external environment.
There are several mechanisms by which molecules can be transported across the plasma membrane of animal cells, including diffusion, facilitated diffusion, active transport, and endocytosis/exocytosis. Each of these mechanisms is regulated in a way that ensures that molecules move in one direction only, thereby maintaining the stability of the internal environment of the cell.
For example, in active transport, molecules are transported against their concentration gradient, from an area of low concentration to an area of high concentration. This process requires the input of energy and is mediated by specific proteins called pumps. These pumps are regulated in such a way that they only transport molecules in one direction, ensuring that the internal environment of the cell remains stable.
Overall, the transport of molecules across the plasma membrane of animal cells is carefully regulated to ensure that it is a one-way path, maintaining the stability of the internal environment of the cell.

The late onset and progressive worsening of mitochondrial diseases is explained through the hypothesis of declining oxidative phosphorylation with ageing.
One of the theories of ageing is the free-radical theory according to which with age, the number of reactive oxygen species in the cells increasingly accumulates that causes damage to the cellular components and results in aging.
This oxidative damage also affects the replication and transcription of the mitochondrial DNA. This results in oxidized bases, strand breaks, abasic sites which result in diseases and due to more accumulation of free radicals, the disease worsens.
