Question 1

Which of the following best describes the genetic relationship between daughter cells and the parent cell after mitosis?

Accepted Answer

Daughter cells are genetically identical to the parent cell.

Question 2

During metaphase of meiosis I, how do chromosomes line up compared to mitosis?

Accepted Answer

Homologous chromosomes pair up and line along the metaphase plate in meiosis I, while individual chromosomes line up in mitosis.

Question 3

How many cell divisions occur during meiosis, and what is the result?

Accepted Answer

Two cell divisions occur, resulting in four haploid daughter cells.

Question 4

Which equation correctly represents the relationship between allele frequencies in a population according to the Hardy-Weinberg principle?

Accepted Answer

$$p + q = 1$$

Question 5

Which enzyme is responsible for unwinding the DNA double helix during DNA replication?

Accepted Answer

Helicase

Question 6

What is the primary function of NADP+ in the light-dependent reactions of photosynthesis?

Accepted Answer

It acts as an electron carrier, becoming reduced to NADPH.

Question 7

Which of the following is a direct measurement of the rate of photosynthesis in plants?

Accepted Answer

The production of oxygen gas

Question 8

Which process results in genetic variation among offspring in sexually reproducing organisms?

Accepted Answer

Crossing over during prophase I of meiosis

Question 9

Which of the following best describes the function of the mitotic spindle during mitosis?

Accepted Answer

It separates sister chromatids to opposite poles of the cell.

Question 10

Which equation represents the genotype frequencies in a population under Hardy-Weinberg equilibrium?

Accepted Answer

$$p^2 + 2pq$$ + $$q^2 = 1$

Question 11

Which of the following is NOT a condition required for Hardy-Weinberg equilibrium?

Accepted Answer

Natural selection must be occurring.

Question 12

Which type of mutation is most likely to cause a frameshift in the genetic code?

Accepted Answer

Insertion or deletion of a nucleotide

Question 13

Which of the following best describes the role of ATP and NADPH in the Calvin cycle?

Accepted Answer

They provide energy and reducing power for the synthesis of organic compounds from CO$$_2.$$

Question 14

Which of the following is a difference between mitosis and meiosis?

Accepted Answer

Meiosis produces four genetically unique haploid cells, while mitosis produces two genetically identical diploid cells.

Question 15

Which structure is responsible for producing sperm cells in the male reproductive system?

Accepted Answer

Seminiferous tubules

Question 16

Which of the following best describes the Central Dogma of molecular biology?

Accepted Answer

DNA is transcribed to RNA, which is translated to protein.

Question 17

Which of the following is a real-world example of artificial selection?

Accepted Answer

Breeding dogs for specific traits such as size or temperament

Question 18

Which of the following best describes the function of the 5’ cap and poly-A tail in mRNA processing?

Accepted Answer

They protect mRNA from degradation and help it exit the nucleus.

Question 19

Which of the following is a mechanism of microevolution?

Accepted Answer

Genetic drift

Question 20

Which equation would you use to calculate the expected genotype frequencies for a population in Hardy-Weinberg equilibrium?

Accepted Answer

$$p^2 + 2pq$$ + $$q^2 = 1$
