The process of protein synthesis on ribosomes is called: MCQ with Answer and Explanation

The process of protein synthesis on ribosomes is called:
A. Replication
B. Transcription
C. Translation
D. Transformation
Answer: Option C
Solution (By JKSSB Mock Tests)
Translation is the ribosome-mediated synthesis of a polypeptide chain according to the mRNA template. tRNA molecules bring amino acids, and peptide bonds form. Replication duplicates DNA, transcription synthesizes RNA from DNA, transformation is genetic uptake by bacteria.

Question #3
Which of the following nitrogenous bases is found in RNA but not in DNA?
A. Cytosine
B. Guanine
C. Uracil
D. Adenine

Correct Answer: Option C


Explanation:
RNA contains uracil instead of thymine found in DNA. In DNA, adenine pairs with thymine; in RNA, adenine pairs with uracil. Adenine, guanine, and cytosine are common to both. Uracil is a pyrimidine base, structurally similar to thymine but lacking a methyl group. This distinction is used in genetic material identification and understanding transcription.
