, BIOD 101 MODULE 4 – PORTAGE LEARNING
1. True or False
Statement: In DNA, adenine pairs with cytosine.
Answer: False
Explanation: In DNA, adenine pairs with thymine, and cytosine pairs with guanine
2. Fill in the Blank
Question: A nitrogenous base plus a deoxyribose sugar is called a ________, and when a
phosphate group is added, it becomes a ________.
Answer: Nucleoside; Nucleotide)
3. Short
Answer
Question: What is the role of histone proteins in DNA structure?
Answer: Histone proteins help package and organize DNA into structural units called
nucleosomes, facilitating the compaction of DNA within the nucleus.
4. Definition
Term: Genome
Definition: The complete set of DNA, including all of its genes, in an organism.
5. True or False
, Statement: During metaphase of mitosis, chromosomes align at the cell's equatorial plane.
Answer: True(
6. Fill in the Blank
Question: The phase of the cell cycle where DNA replication occurs is called the ________
phase.
Answer: S phase
7. Short
Answer
Question: Explain the significance of the antiparallel arrangement of DNA strands.
Answer: The antiparallel arrangement allows the two strands of DNA to form hydrogen bonds
between complementary bases, facilitating the double helix structure and proper replication.
8. Definition
Term: Somatic Cell
Definition: Any cell of the body except sperm and egg cells; somatic cells are diploid,
containing two sets of chromosomes.
9. True or False
Statement: Pyrimidines have a double-ring structure.
Answer: False
Explanation: Pyrimidines have a single-ring structure; purines have a double-ring structure.(
