Question

A length or double stranded DNA contains 120 nudeotides and codes for polypeptide x What is the maximum angth of
polypeptider​

Answer 1

20 as DNA IS DOUBLE STRANDED EACH WOULD HAVE 60 and As ONE CODE HAS 3 NUCLEOTIDES 60÷3~20

Answer 2

Assuming that the DNA codes for a polypeptide without any stop codons, the maximum length of the polypeptide that can be coded by the DNA containing 120 nucleotides would be 40 amino acids, since each amino acid is coded for by three nucleotides.

The maximum length of the polypeptide that can be coded by a DNA molecule containing 120 nucleotides would depend on the specific sequence of the nucleotides and the genetic code being used.

In general, the genetic code specifies that each set of three nucleotides, known as a codon, codes for a specific amino acid. Therefore, the maximum length of the polypeptide would depend on the number of amino acids that can be coded for by the 120 nucleotides in the DNA.

Since there are 20 different amino acids commonly found in proteins and 64 possible codons, some amino acids can be coded for by multiple codons. However, there are also three codons that do not code for any amino acids and instead serve as stop signals for protein synthesis.
