Below is the double-stranded DNA sequence of part of a hypothetical yeast genome. Within this sequence is a small gene, PICO8, that codes for an 8 amino-acid peptide (assume traditional start codon). Transcription of PICO8 starts at the Transcription Start Site (TSS) after the promoter and proceeds in the direction of the arrow. Transcription stops at the end of the transcription terminator.

Answer:

D. There isn't enough information to determine which is the coding strand

Explanation:

In this protein, it would be necessary to observe a start codon (ATG) and one-stop codon (either TAA, TAG, or TGA) which should be separated by six (6) intern codons. It is not observable this nucleotide sequence in any of both DNA strands.

Transcription and Translation are the two steps of the central dogma, in which genetic information from the DNA is converted into the RNA, then a long chain of polypeptides.

The correct answer is:

Option A. Top

In the given sequence of the hypothetical yeast genome, the PlCO8 gene codes for a small peptide chain of 8 amino acids.

The transcription starts from the traditional start site, in which the nucleotides in the template strand are converted into the corresponding base pair in the mRNA.

In the given sequences of nucleotides, the coding strands will be the strand that runs in the direction of 5'-3'.

The codes from the coding strand are then transcribed into the mRNA, followed by the translation.

Therefore, option A is correct.
