CHAPTER 1: NUCLEIC ACIDS AND PROTEINS QUESTIONS
This chapter introduces the structure and function of nucleic acids and
proteins, emphasizing DNA, RNA, chromosomes, amino acids, and
protein synthesis. It explores molecular genetics principles, gene
organization, replication, transcription, translation, and mutations.
Understanding these concepts enables healthcare professionals to
interpret molecular diagnostics, analyze genetic disorders, and apply
molecular biology principles safely and accurately in clinical
laboratory practice.
1. Which nitrogenous base is found in RNA but not DNA?
A. Thymine
B. Cytosine
C. Uracil
D. Guanine
, Correct Answer: C
Rationale: Uracil replaces thymine in RNA. DNA contains thymine,
whereas RNA contains uracil paired with adenine during transcription
and protein synthesis.
2. A laboratory scientist identifies a double-stranded nucleic acid
containing thymine. Which molecule is present?
A. mRNA
B. tRNA
C. DNA
D. rRNA
Correct Answer: C
Rationale: DNA is double stranded and contains thymine. RNA
molecules are generally single stranded and contain uracil instead of
thymine.
3. Which structure is responsible for carrying amino acids during
protein synthesis?
A. mRNA
B. tRNA
