Question 1

Which of the following describes the cell division process undergone by germline stem cells to produce mature haploid gametes?

Meiosis, which involves two successive nuclear divisions resulting in four haploid gametes Mitosis, which involves a single nuclear division resulting in two genetically identical diploid daughter cells Binary fission, which results in unequal cytoplasmic division between daughter cells Apoptosis, which leads to programmed degradation of cellular DNA without cell division

Correct Answer:

Meiosis, which involves two successive nuclear divisions resulting in four haploid gametes

Question 2

How do pluripotent embryonic stem cells differ from multipotent adult tissue stem cells?

Pluripotent embryonic stem cells can differentiate into all human cell types, whereas multipotent tissue stem cells can only differentiate into cell types of their specific tissue Pluripotent embryonic stem cells are limited to forming blood cells, whereas multipotent tissue stem cells can form any tissue type Pluripotent embryonic stem cells contain only half the diploid chromosome complement, whereas multipotent stem cells are polyploid Pluripotent embryonic stem cells divide exclusively by meiosis, whereas multipotent tissue stem cells divide by binary fission

Correct Answer:

Pluripotent embryonic stem cells can differentiate into all human cell types, whereas multipotent tissue stem cells can only differentiate into cell types of their specific tissue

Question 3

Which option correctly matches a therapeutic use of stem cells with a research use of stem cells?

Therapeutic: Corneal repair surgery; Research: Testing new pharmaceutical drugs for toxicity Therapeutic: Modeling Parkinson's disease progression; Research: Skin graft transplantation for burn victims Therapeutic: Analyzing gene expression patterns; Research: Bone marrow transplantation for leukemia Therapeutic: Synthesizing recombinant insulin; Research: Performing routine antenatal diagnostic karyotyping

Correct Answer:

Therapeutic: Corneal repair surgery; Research: Testing new pharmaceutical drugs for toxicity

Question 4

What structural feature of the DNA double helix explains why the two sugar-phosphate backbones run in opposite directions?

The antiparallel orientation of the strands, where one strand runs 5' to 3' and the complementary strand runs 3' to 5' The presence of uracil bases bound to ribose sugars in place of thymine The covalent peptide bonds connecting complementary nitrogenous bases across the helix axis The triple helix coil stabilized by ionic bonds between adjacent phosphate groups

Correct Answer:

The antiparallel orientation of the strands, where one strand runs 5' to 3' and the complementary strand runs 3' to 5'

Question 5

During DNA replication in human cells, why is a short RNA or DNA primer required before DNA polymerase can begin synthesis?

DNA polymerase requires an existing 3' hydroxyl group to attach the first incoming deoxyribonucleotide The primer unwinds the hydrogen bonds holding the parental template strands together DNA polymerase cannot recognize purine bases without a primer bound to the 5' end The primer acts as an enzyme that ligates Okazaki fragments on the leading strand

Correct Answer:

DNA polymerase requires an existing 3' hydroxyl group to attach the first incoming deoxyribonucleotide
