DNA Vocab

Question 1

DNA

Answer 1

A double stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell’s proteins.

Question 2

Deoxyribose

Answer 2

A five-component sugar that is a component of DNA nucleotides

Question 3

Purine

Answer 3

A class of nucleotides that includes adenine and guanine

Question 4

Pyrimidine

Answer 4

A class of nucleotides that includes cytosine, thyamine, and uracil.

Question 5

Helicase

Answer 5

An enzyme that untwists the double helix of DNA at the replication forks, separating the two strands and making them available as template strands.

Question 6

DNA Polymerase

Answer 6

An enzyme that catalyzes the elongation of new DNA at a replication fork by the addition of nucleotides to the existing chain.

Question 7

Base-Pairing

Answer 7

The rules stating that in DNA cytosine pairs with guanine and adenine pairs with thymine and that in RNA cytosine pairs with guanine and adenine pairs with uracil

Question 8

RNA

Answer 8

A type of nucleic acid consisting of nucleotide monomers with a ribose sugar and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and uracil (U); usually single-stranded; functions in protein synthesis, gene regulation, and as the genome of some viruses.

Question 9

Nucleotide

Answer 9

Repeating monomers in DNA and RNA; consist of a phosphate group, 5-carbon sugar, and a nitrogen base

Question 10

Nucleic Acid

Answer 10

CHONP - used for genetic information storage (DNA), interpreting genetic info (RNA), and also the source of cellular energy to do anything for everything alive.
