Question

The term "genetic code" is defined as the sequence of bases in DNA in a cell’s nucleus. The bases in the genetic code are:

A) The same in animals and bacteria, and different in plants
B) The same in animals, plants, and bacteria
C) Different in bacteria and animals
D) Different in animals and plants

Answer 1

The genetic code is the sequence of bases in DNA or RNA. It consists of codons, which are groups of three bases that encode one amino acid. There are 64 possible codons, which can code for all 20 common amino acids, allowing for redundancy.

Step-by-step explanation:

The genetic code is the sequence of nitrogen bases in a polynucleotide chain of DNA or RNA. The bases are adenine (A), cytosine (C), guanine (G), and thymine (T) (or uracil, U, in RNA). These four bases make up the 'letters' of the genetic code. They are combined in groups of three to form code 'words,' called codons. Each codon encodes one amino acid, unless it codes for a start or stop signal. There are 64 possible codons, which is more than enough to code for the 20 amino acids we commonly find in proteins. Therefore, more than one codon codes for a single amino acid.
