Question

The universal genetic language of DNA is common to virtually all organisms on Earth, however diverse. What is the best explanation for this fact?

a. all living things share a common genetic language of DNA because they share a common ancestry
b. the universal genetic language is explained by the chemistry of DNA and proteins
c. the universal nature of the genetic language of DNA is due to coincidence

Answer 1

Answer:

b

Explanation:

this is because everyones DNA is different, meaning that A is incorrect. C is incorrect because DNA is not a coincidence, its a complicated thing and just one wrong thing can lead to many bad things like down syndrome

Answer 2

The universal genetic code of DNA is common to virtually all organisms on Earth it is because all living things share a common genetic language of DNA because they share a common ancestry. Thus Option A is correct.

what is genetic code?

Genetic code refers to the instructions in DNA of our body is converted codon found in mRNA, finally in protein.  

All genes codes for four types of nucleotide bases such as adenine (A), cytosine (C), guanine (G) and thymine (T).

These are represented in three letter word called codon which specify one amino acid, basic unit of protein.

The genetic code is important as it produce the products which is  necessary for the survival and the information can be passed to next generation.

It is  arbitrary due to the fact that all organisms share a single genetic code is due to their common ancestor. Hence, Option A is correct.
