Flashcards in biology ch 12 Deck (17):
1

nucleotide

monomers that make up DNA

2

double helix

two strands wound around each other

3

replication

THE PROCESS OF MAKING COPIES Of DNA

4

DNA polymerase

enzyme responsible for DNA replication

5

functions of nucleic acid

they're macromolecules that store or transmit RNA - genetic information

6

three different pars of a nucleotide

1. 5 carbon sugars
2. phosphate group
3. nitrogenous bases

7

4 possible nitrogenous bases that a nucleotide can have for DNA.

ademne, thymine, cytosine, and guanine

8

Which of the nitrogenous bases are pyrimidines?

thymine and cytosine

9

Know which nitrogenous base pairs bind together according to complementary base pairing; Understand how this is supported by Chargaff’s rules.

A=T
C=G

10

TCGACATGATTACACGGC

AGCTGTACTAATGTGCCG

11

James Watson

put everything together

12

francis crick

worked out the math

13

rosalind franklin

took x-ray pictures of what DNA structures looked like

14

maurice wilkins

what the dna is shaped like - twisted ladder

15

erwin chargaff

discovered two rules that helped lead to the discovery of the double helix structure

16

Linus Pauling

discovered that the amounts of adenine and thymine in DNA were roughly the same, as were the amounts of cytosine and guanine

17

which are purines

Ademne + Guanine are purines
