Question

A particular eukaryotic protein is 300 amino acids long. Which of the following could be the minimum number of nucleotides in the DNA that codes for the amino acids in this protein?

Answer 1

Answer:

The correct option is 900.

Explanation:

A codons can be described as a sequence of amino acids which codes for a particular protein. Each protein is made according to the specific kind of codon. The genetic code determines the codons. The codons usually are made in the form of triplets i.e they are made up of a sequence containing three pairs of nucleotides.

Hence, based on the genetic code, the minimum number of nucleotides for a making a 300 amino acid long protein would be 900.

Answer 2

Eukaryotic proteins are the polypeptide sequences that code for the function and cellular activities. 900 nucleotides will be required to code for 300 amino acids.

What is amino acid and codons?

Amino acids are the basic monomer units of the proteins and are arranged in the form of three nucleotides placed together to form a  triplet codon.

The set of triplet codon codes for a particular protein in a cell is defined by a genetic code. So, for forming a 300 long amino acid sequence 900 nucleotides will be required.

Therefore, 900 nucleotides will be required.
