What effect does the size of an amino acid on the retention factor?

2 answers:

6 0

According to proteomic data analysis, the N-terminus residues highly influence the retention of amino acids due to their role in ion-pairing. Every amino acid has a retention coefficient factor depending on the N-terminus residues it contains. Therefore, the longer the amino acid the higher the likelihood of it having high N-terminus residues and consequent high retention co-efficient.

<span>The retention factor is a value used by chemists performing thin-layer chromatography which indicates the distance a particular compound traveled across a stationary phase in contrast to the solvent. While the size of an amino acid is not the only factor involved, generally, the larger the amino acid, the slower it will travel, ultimately leading to a smaller retention factor.</span>

dalvyx [7]

Answer:

The question lacks options, the options are:

A). the body cell has 2n; the sex cell has 1n.

B). the body cell has 26; the sex cell has two.

C). the body cell has 1n; the sex cell has 2n.

D). the body cell has 24; the sex cell has 26

The answer is A

Explanation:

According to the question, the snapping turtle possesses 52 chromosomes in its cell. This means that the chromosomal number of its body cell is 52. However, the turtle, which reproduces sexually will produce gametes or sex cells via meiosis. Meiosis is the kind of cell division that results in daughter cells (gametes) that have a reduced number of chromosomes (by half).

Based on this, the diploid cells (2n) of the turtle with chromosome number 52 will undergo meiotic division to produce haploid gametes or sex cells (n) with chromosome number 26.

N.B: Diploid (2n) means two complete sets of chromosomes while haploid (1n) means one complete set of chromosome.

The body cell of the turtle contains two set of chromosomes received from each parent, hence, making it Diploid (2n). However, meiosis will reduce the chromosome number to one set in each gamete i.e. haploid (n).

zhannawk [14.2K]

The answer is captive breeding.

Captive breeding involves breeding animals in a controlled environment.

What is captive breeding?

The technique of keeping plants or animals in confined spaces, such as zoos, botanical gardens, and other conservation facilities, is known as captive breeding, sometimes known as captive propagation. It is occasionally used to support species that are under threat from human activities including climate change, habitat loss, fragmentation, excessive fishing or hunting, pollution, predation, illness, and parasitism.

Relatively little is known about the circumstances necessary for effective breeding in many species. The success of a captive breeding program may depend on knowledge of a species' reproductive biology. Captive breeding programs have the potential to preserve some species from extinction, but they depend on a variety of criteria, including genetic, ecological, behavioral, and ethical considerations.
