Question

How many reading frames are encoded by the sense nucleotide strand?

a) 1
b) 2
c) 3
d) 6

Answer 1

The sense nucleotide strand encodes three reading frames.

Step-by-step explanation:

In molecular biology, the process of translating an RNA sequence into a protein involves reading the nucleotide sequence in groups of three, known as codons. The sense nucleotide strand is the strand of DNA or mRNA that contains the same sequence as the RNA molecule being transcribed or the protein being translated. Each codon encodes for a specific amino acid, and the number of reading frames in an RNA sequence depends on the number of possible ways to group the nucleotides into codons.

Since each codon consists of three nucleotides and the reading frame can start at any position within the RNA sequence, there are three potential reading frames encoded by the sense nucleotide strand.

Therefore, the correct answer is c) 3.
