Genomic libraries have many uses in genetics research. The FALSE statement regarding genomic libraries is: They are a collection of different restriction enzymes.

Genomic libraries are collections of clones or vectors that contain genomic DNA inserts. Each clone contains a segment of the DNA of the species of interest. Researchers can create genomic libraries by cloning large genomic DNA fragments into a suitable vector. These libraries can be used to identify and isolate specific genes or DNA sequences of interest. Therefore, option A, "They are a collection of different restriction enzymes" is false. The correct statement is that genomic libraries are made by molecular cloning. They are a collection of clones and a collection of plasmids. Each cloned plasmid in the library contains a different segment of the genome.

A full collection of cloned DNA snippets that make up an organism's whole genome is known as a genomic library or gene bank. It represents every gene, including exons, introns, and expressed and non-expressed forms. Genomic libraries can be preserved for a long time, and copies can be used for analysis.

Acid rain harms numerous animals and plants. Thus, the food web suffers. Acid rain kills lake phytoplankton. As a result, phytoplankton-dependent insects die. Therefore, option (C) is correct.

Acid rain, also known as acid deposition, is an all-encompassing word that refers to any form of precipitation that contains acidic components, such as sulfuric or nitric acid, and that falls to the ground from the atmosphere in either a wet or dry form. Acid precipitation can take several forms, such as rain, snow, fog, hail, or even dust.

Rain that contains acid can provide significant challenges for a wide variety of flora and fauna. As a direct consequence of this, the entire food web is disrupted. For instance, phytoplankton in lakes might perish as a direct result of acid rain. As a result of there being less phytoplankton available, the insects, which get their nutrition from it, are starting to starve to death.

A gene of interest can be cut from a genome using restriction enzymes and can be incorporated into another genome using ligases in the recombinant DNA technology.

Recombinant DNA technology can be described as a method of genetic engineering where DNA from one organism is incorporated into another one.

The process of recombinant DNA technology occurs as follows:

The gene of interest of the desired organism is cut by using restriction enzymes. The restriction sites for the gene of interest should be similar to the vector where it has to be pasted.

After isolating the gene of interest, it is incorporated into a vector using ligases.

After this gene has successfully been incorporated into a vector, the vector is placed into a host cell.

When the host cell divides, the vector also multiplies. These cells containing foreign DNA can be screened through various screening procedures. Usually, a selectable marker is used.

The two strands of DNA are antiparallel, meaning that they run in opposite directions. One strand runs in the 5' to 3' direction, while the other runs in the 3' to 5' direction. This antiparallel orientation is essential for DNA replication and protein synthesis.

The two strands are held together by hydrogen bonds between complementary base pairs, with adenine (A) bonding with thymine (T) and guanine (G) bonding with cytosine (C). Additionally, the sugar-phosphate backbone of each strand is covalently linked through phosphodiester bonds.

The combination of these bonds creates the double helix structure of DNA. The antiparallel nature of the strands allows for the complementary base pairing and covalent bonding that make up the stable structure of DNA.

The ranking considers the relative ionizing power and energy deposition characteristics of each radiation type. Alpha particles, due to their high ionization density and short range, pose the highest risk per unit absorbed dose.

Ranking the different types of radiations in terms of their harmfulness per unit absorbed dose:

1. Alpha (α) particles: Alpha particles have a relatively large mass and charge, making them highly ionizing and more harmful per unit absorbed dose. They deposit a significant amount of energy in a short distance, causing severe damage to tissues and organs.

2. Beta (β) and gamma (γ) radiations: Beta and gamma radiations are less harmful per unit absorbed dose compared to alpha particles. They have lower ionizing power and can penetrate deeper into tissues. While still potentially harmful, their ability to cause damage is generally lower than that of alpha particles.

3. Protons: Protons, despite having a mass and charge similar to alpha particles, are less harmful per unit absorbed dose. They deposit energy over a larger distance, resulting in a lower concentration of energy deposition in tissues. This makes them relatively less damaging compared to alpha particles.

Beta and gamma radiations have lower ionization density and can penetrate tissues more deeply. Protons, while still ionizing, deposit energy over a larger range, reducing their harmfulness per unit absorbed dose.

The base composition of the virion DNA of an E. coli phage, such as ΦX174, can provide important information about the structure and function of the phage's chromosome.

The high proportion of thymine and the unique combination of nitrogenous bases in ΦX174's virion DNA suggest a role in the stability and efficient replication of the phage.

The virion DNA of an E. coli phage, also known as bacteriophage ΦX174, contains the genetic information that is used to infect and replicate within a host bacterium.

The base composition of the virion DNA, or the proportion of different nitrogenous bases that make up the DNA, can provide important information about the structure and function of the phage's chromosome.

In the case of ΦX174, the virion DNA has a base composition of 25% adenine (A), 33% thymine (T), 24% guanine (G), and 18% cytosine (C). This composition is unique among phages and bacteria and is thought to play a role in the stability and function of the phage chromosome.

One possible explanation for the high proportion of thymine in the virion DNA of ΦX174 is that it may play a role in the stability of the chromosome. The high number of thymine-adenine base pairs in the DNA can help to maintain the stability of the chromosome, preventing breakage and damage to the genetic information.
