Question

A diagram of a cellular process is shown below.

DNA
RNA
Protein
Which of the following identifies the process shown at point Y?
A. Translation
B. Translocation
C. Replication
D. Transcription

Answer 1

Y : Transcription

Step-by-step explanation:

X: Replication

• Process in which a cell makes an exact copy of its own DNA.

Y: Transcription

• Process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis.

Z: Translation

• Process by which mRNA directs protein synthesis with the assistance of tRNA.

Answer 2

The process shown at point Y is known as Transcription (Option D).

What is transcription?

Transcription is the process by which an RNA molecule is synthesized from a DNA template. It involves the reading of a specific segment of DNA (a gene) and the synthesis of a complementary RNA molecule.

This newly synthesized RNA molecule, known as messenger RNA (mRNA), carries the genetic information from the DNA to the ribosomes, where protein synthesis (translation) occurs.

Given that the process at point Y in the diagram involves the synthesis of RNA from DNA, the correct answer is: D. Transcription.
