Bio 210: Module 8/ 99 Questions &
Answers/ 2024.
1 What is genetics-Answer:
Study of genes
2 What are genes -Answer:
Segment of DNA coding for a functional product
3 What is a chromosome-Answer:
Structure of DNA coding for a functional product
4 What is a genome-Answer:
1|Page
,All the genetic information in a cell
5 What is genomics-Answer:
The molecular study of genomes
6 What is genotype-Answer:
The genes of an organism
7 What is a phenotype -Answer:
Expression of the genes
8 The duplication of a cell's DNA -Answer:
Replication
9 The DNA molecule is composed of building blocks -Answer:
nucleotides
10 The polymer of DNA is
Nucleic acid
11 What 3 things does every nucleotide consist of-Answer:
1. one sugar (deoxyribose)
2. one phosphate group
3. One of four bases: adenine, guanine, thymine, or cytosine (A, G, T, or C)
12 What does the backbone of DNA consist of-Answer:
sugar phosphate
13 Which nucleotides pair together in complementary base pairing-Answer:
2|Page
, A always pairs with T across the helix, while G always pairs with C.
14 Why do purines pair with pyrimidines-Answer:
Because it creates DNA double double helix with uniform diameter and width is
consistent with x-ray data. If paired purine +purine = too wide. If paired
pyrimidine + pyrimidine = too narrow.
15 What is the complementary sequence for a segment of DNA with the sequence
GTCCAC-Answer:
C, A, G, G, T,G
16 What does it mean to say that the two strands in a DNA double helix are
antiparallel-Answer:
The strand runs from 5' ---> 3' of one strand turns counter to the 3' ---> 5'
direction of the other strand. ---> sugar phosphate backbones run in opposite
direction.
17 What type of bond holds complementary bases together of adjacent strands of
DNA-Answer:
Hydrogen bond
18 What type of bond holds together the backbone on a DNA strand (joining the
sugar and phosphate together of adjoining nucleotides)-Answer:
Covalent bond
19 What are the products of the replication of one DNA molecule-Answer:
3|Page
