This section is designed for students preparing for competitive examinations where precision, conceptual depth, and speed are critical. It focuses on the most frequently tested and high-yield areas of transcription and translation, with strong emphasis on NCERT line-based understanding and exam-oriented practice.
In this section, you will study:
High-yield steps and enzymes involved in transcription and translation
Tricky distinctions between prokaryotic and eukaryotic gene expression
NCERT-based MCQs on RNA polymerase, ribosomes, and translation factors
Genetic code–based questions and common conceptual traps
Assertion–reason and multi-statement questions
Regulation of gene expression in competitive exam context
Previous year question patterns and exam-focused practice sets
The content is structured to improve accuracy, conceptual clarity, and exam temperament, helping students confidently tackle high-difficulty MCQs and theory-based questions in NEET and other competitive entrance exams.
Build a competitive edge by mastering transcription and translation with focused, exam-oriented preparation.
Q. What is the role of ribosomes in protein synthesis?
A.
To transcribe DNA into RNA
B.
To translate mRNA into polypeptides
C.
To replicate DNA
D.
To splice introns from mRNA
Solution
Ribosomes are the cellular machinery that translates mRNA into polypeptides, facilitating protein synthesis.
Correct Answer:
B
— To translate mRNA into polypeptides
Q. Which of the following best describes a frameshift mutation?
A.
A mutation that changes one amino acid
B.
A mutation that adds or removes nucleotides, altering the reading frame
C.
A mutation that duplicates a segment of DNA
D.
A mutation that occurs in non-coding regions
Solution
A frameshift mutation occurs when nucleotides are added or removed from the DNA sequence, shifting the reading frame and altering the resulting protein.
Correct Answer:
B
— A mutation that adds or removes nucleotides, altering the reading frame
