Explanation:

Question 27

Transcription is the process where DNA is used as a template to synthesize mRNA. The diagram shows a DNA strand paired with an mRNA strand, which matches the transcription process. Respiration is about energy production, mutation is a change in DNA sequence, and translation is about synthesizing proteins from mRNA. So the correct process is transcription.

Step1: Analyze each codon

First, take the mRNA codons: UAC, UCU, ACC.

Step2: Find amino acid for UAC

Using the codon table, UAC codes for Tyrosine (Tyr).

Step3: Find amino acid for UCU

UCU codes for Serine (Ser).

Step4: Find amino acid for ACC

ACC codes for Threonine (Thr).

In the context of translation, the structure E (from the diagram, likely part of tRNA) that pairs with the mRNA codon is the anticodon. A codon is on mRNA, a nitrogen base is part of a nucleotide, and a nucleotide is the building block of nucleic acids. So structure E is an anticodon.

Answer:

a. Transcription
