The correct answer is B. They evolved from a shared ancestor
Explanation:
In biology, the word clay refers to a set of organisms that have a common ancestor and because of this, they are placed in the same ramification or branch in a phylogenic tree, which allows biologists to classify organisms in groups. For example, all birds are believed to have a common ancestor and therefore they formed a clade. However, belonging to the same clade does not imply the same exact classification, identical phylogenies or characteristics because these depend on each species and varies due to the evolution process. Therefore the statement that is true about organisms that are part of the same clad ie that they evolved from a shared ancestor.
Answer: 64 codons
Explanation:
The triplet nature of the genetic code make for a possible 64 codons: 61 code for amino acids present in most polypeptide chains while the remaining 3 are special-sense codons, since they only signal for the termination of the polypeptide chain.
Thus, the pattern of the genetic code permits that a base appear more than once in a codon. For instance Adenine occurs twice in both AAU and AAC codons, which code for asparagine.
