Question

question 2
go to what is dna?
review all images and read the text, then match the following: (you will not use all terms)
column a

1. d genome
2. c hydrogen bonds
3. antiparallel
4. the human genome
5. double helix structure

column b
a. discovered by francis crick and james watson with the help of rosalind franklin and maurice wilkins.
b. sense and nonsense
c. two strands run in the opposite direction to each other so that one runs 5 to 3 and one runs 3 to 5
d. made of 3.2 billion bases
e. made of a chemical called deoxyribonucleic acid
f. joins together each base pair
g. 2 meters

Explanation:

• Antiparallel: The term "antiparallel" in DNA refers to the orientation of the two strands. As per the definition in option c, in a DNA molecule, the two strands run in opposite directions - one from 5' to 3' and the other from 3' to 5'.
• The human genome: The human genome is composed of a vast number of base pairs. Option d states "Made of 3.2 billion bases", which is a characteristic of the human genome.
• Double helix structure: The double - helix structure of DNA was discovered by Francis Crick and James Watson with the help of Rosalind Franklin and Maurice Wilkins. This matches option a.

Answer:

1. c
2. d
3. a
