Answer:

Both species are mammals and therefore they share genome regions and gene families that are conserved in the course of evolution.

Explanation:

Synteny enables to identify conserved genome regions between species by aligning their DNA sequences. For example, the human and chimpanzee genomes share about 95-98% of synteny (sequence similarity) in their DNA sequences. In this case, a whole-genome sequence similarity of 80 % is evidence that both species are relatively closely related and share a near common ancestor. Indeed, it is expected that the most part of the remaining 20% represents mutations associated with the fixation of neutral alleles (i.e., neutral mutations) and therefore have no evolutionary meaning.

MAXImum [283]

Answer:

chitin and murein

Explanation:

The chemical compounds that distinguish bacteria cell from yeast cell are  

chitin and murein

Chitin is a polysaccharide present in the exoskeleton of fungi made up of chains of modified glucose known as N-acetylglucosamine. N-acetylglucosamine is derived from glucose

While murein is a mesh like structure made up of sugar and amino acids. Murein forms a layer outside the plasma membrane of bacterial cell.

How many distinct trnas are needed to translate every codon in the genetic code?
White raven [17]
In the genetic code, codons made of of three bases specify an amino acid. With three bases, there are 64 possible permutations. With three codons corresponding to STOP codons, this leaves 61 combinations that code for an amino acid. This would require 61 distinct tRNA species were it not for the "wobble base"
