Question 1

Which of the following statements best describes the Chromosome Theory of Inheritance?

Accepted Answer

Inherited traits are controlled by genes residing on chromosomes, which are faithfully transmitted through gametes and maintain genetic continuity from generation to generation.

Question 2

What is the primary difference between mitosis and meiosis in eukaryotic cells?

Accepted Answer

Mitosis results in daughter cells with a diploid set of chromosomes identical to the parental cell, while meiosis produces gametes with a haploid set of chromosomes.

Question 3

Which experiment provided solid proof that DNA, not protein, carries genetic information in bacteria?

Accepted Answer

Avery, MacLeod, and McCarty's 1944 experiment

Question 4

Which of the following is NOT a characteristic of a good model organism for genetic studies?

Accepted Answer

Long life cycle

Question 5

CRISPR-Cas technology is considered revolutionary in genetics because it is:

Accepted Answer

More accurate, efficient, versatile, and easier to use than previous gene editing methods

Question 6

If a human cell has a diploid number of 46 chromosomes, how many chromosomes will be present in a gamete after meiosis?

Accepted Answer

$$23$$

Question 7

Which process is essential for understanding Mendel's laws of genetics?

Accepted Answer

Meiosis

Question 8

What is the correct sequence of events in gene expression?

Accepted Answer

Transcription of DNA into mRNA, followed by translation of mRNA into protein

Question 9

Which of the following best defines an allele?

Accepted Answer

An alternate form of a gene

Question 10

Which Nobel Prize was awarded for the development of CRISPR-Cas technology?

Accepted Answer

2020 Nobel Prize in Chemistry

Question 11

A transgenic crop is best described as:

Accepted Answer

A crop with genes for herbicide resistance, insect resistance, or nutritional enhancement introduced from another organism

Question 12

Which of the following equations correctly represents the diploid number ($$2n) $$and haploid number ($$n) in $$humans?

Accepted Answer

$$2n = 46$$, $$n = 23$$

Question 13

Which of the following is a direct application of recombinant DNA technology in the biotechnology industry?

Accepted Answer

Production of genetically modified crops with enhanced traits

Question 14

Which model organism is commonly used for genetic analysis due to its short life cycle and ease of growth?

Accepted Answer

Drosophila melanogaster

Question 15

Which of the following best describes the process of DNA cloning?

Accepted Answer

Transferring recombinant DNA molecules into bacterial cells for reproduction of thousands of copies

Question 16

Which field focuses on the study of all genes in an organism and their interactions?

Accepted Answer

Genomics

Question 17

Which of the following is a mutation?

Accepted Answer

Any heritable change in DNA sequence

Question 18

Which process is illustrated by the equation $$DNA \rightarrow mRNA \rightarrow Protein$$?

Accepted Answer

Central Dogma of Molecular Biology

Question 19

Which of the following statements about biotechnology and food supply is correct?

Accepted Answer

70% of processed U.S. foods contain transgenic crops
