Answer:

E) 1800

Step-by-step explanation:

because DNA is first transcribed in to single stranded RNA which encodes for amino acid.

each 3 nucleotide of mRNA encode 1 amino acid

so for 300 amino acids = 900 nucleotide of mRNA

so for DNA which is double stranded= 900 x 2 = 1800

so 1800 total nucleotide are there in the DNA which is transcribed to form 900 nucleotide of mRNA and later translated to 300 amino acids of protein.
