Question

Which statement is TRUE about the genetic code?

Group of answer choices

The first position of the codon is always adenosine.

There are 20 different codons.

Every codon encodes an amino acid.

There is no redundancy in the genetic code.

Several different codons may encode the same amino acid.

Answer 1

Ans: d) Several defferent codons may encode same amino acids.

The first postion of codon is not always essential to presence of Adenosine.

There are 64 different codons are present out of them 61 codons encode amino acids and 3 codons are stop codons.

Every codons does not encode amino acids because STOP codons does not encode amino acids.

There is redundancy in genetic code because same amino acids may encode by more then one codons.

Hence only option d is correct.
