A student is studying the amino acid sequence of a protein shared by four organisms. The student wants to know which organism is

most closely related to organism A. The student has data that shows the number of amino acid differences between organism A and each of the other organisms. Study the data in the chart.

Answer:

Organism D.

Explanation:

Amino acids are the monomers of proteins and are linked together by the peptide bond. The protein is obtained from the RNA molecules by the process known as translation.

The amino acid sequence of the proteins can also be used to study the evolutionary relationship between the organisms and the closeness of teh organisms with each other. In the question it is give that organisms A and D has least difference ( 1 amino acid sequence difference) and more related with each other.

Thus, the answer is organism D.

False

Explanation:

ANEK [815]

Answer:

c. The P allele is less frequent in the US than the p allele.

Explanation:

If people with the heterozygous genotype "Pp" present polydactyly, only people with the genotype "pp" will not present polydactyly. Since 99.9% of the population do not exhibit polydactyly, then it can be concluded that the "p" allele is much more frequent in the US than the "P" allele.

Therefore, the answer is:

c. The P allele is less frequent in the US than the p allele.

Prader-Willi syndrome is a genetic disorder involving a partial deletion of chromosome 15q on the paternal chromosome. When both
Kay [80]

Answer:

genomic imprinting

Explanation:

Genomic imprinting is a mechanism for regulating gene expression that allows expression of only one of the parental alleles, although both alleles are functional. Unlike most genes in which expression is biallelic, genes that are subjected to this mechanism (imprinted genes) have monoalelic expression; By definition, in an imprinted loci, only one allele is active (maternal or paternal), and the inactive is epigenetically marked by histonic modification and / or methylation of cytosines.

Genomic imprinting can cause some disturbances, among them Prader-Willi syndrome, which is a genetic disorder that involves a partial deletion of chromosome 15q on the paternal chromosome.
