This section focuses on numerical, quantitative, and data-based problems related to transcription and translation. It is designed for Class 11–12 students, NEET aspirants, and undergraduate learners to strengthen their ability to apply molecular biology concepts using calculations and logical analysis.
In this section, you will practice:
Numerical problems based on nucleotide count and base pairing
Calculations involving mRNA length, codon number, and amino acid sequence
Data-based questions on transcription units and gene structure
Quantitative analysis of mutations and their effect on protein length
Interpretation of tables and graphs related to gene expression
NCERT-aligned numerical questions and exam-oriented practice sets
The content is structured to improve step-by-step calculation skills, enhance data interpretation, and help students confidently handle numerical and logic-based questions in school examinations, NEET, and undergraduate assessments.
Develop speed, accuracy, and confidence in solving numerical applications related to transcription and translation through systematic practice.
Q. During transcription, which enzyme synthesizes RNA from a DNA template?
A.
DNA polymerase
B.
RNA polymerase
C.
Ribosome
D.
Ligase
Solution
RNA polymerase is the enzyme responsible for synthesizing RNA from a DNA template during the process of transcription.
B.
A mutation that adds or removes nucleotides, altering the reading frame
C.
A mutation that occurs in non-coding regions
D.
A mutation that duplicates a segment of DNA
Solution
A frameshift mutation occurs when nucleotides are added or deleted from the DNA sequence, shifting the reading frame and potentially altering all downstream amino acids.
Correct Answer:
B
— A mutation that adds or removes nucleotides, altering the reading frame
