1

process of DNA sysnthesis

replication

2

process of RNA synthesis

transcription

3

process of protein synthesis

translation

4

universal flow of genetics

One direction- DNA-RNA- Protein

5

where does translation ( protein synthesis) occur inside a prokaroyte cell? eukryote?

out the nucleus for both

6

where does transcription (RNA synthesis) occur inside a prokaroyte and eukaroyte cell?

in the eukarote cell it is inside the nucleus, prokaryote has no nucleus

7

how is DNA copied

DNA polymerase

8

What initiates DNA polymerase

RNA primer

9

adds nucleotides to the growing DNA strand, 5’ to 3’ end

DNA polymerase

10

relaxing supercoiling ahead of the replication fork

DNA gyrase

11

Makes covalent bonds to join DNA strands, Okazaki fragments, and new segments in excsion repair

DNA ligase

12

Where does DNA replication take place in bacteria and in eukaryotic cells?

Inside the nucleus

13

strands of the DNA double helix used to make RNA

Template strand

14

strand of DNA complementary to the template strand

coding strand

15

binds DNA at the promoter

RNA polymerase

16

link between RNA structure and protein aa sequence

genetic code

17

how many types of DNA are essential for translation?

3 types

18

transcribed to make 3 major parts of RNA

DNA

19

3 major parts of RNA are

messenger RNA, transfer RNA, Ribosomal RNA

20

Carries amino acids to ribosomes for translation

transfer RNA

21

Contains the information copied from DNA that encodes proteins

messenger RNA

22

3 functions of of ribosomes are

decode mRNA and form peptide bonds

23

true/ false : RNAs and proteins that make up ribosomes are different in bacteria vs. eukaryotes

true

24

a permenant change in the base sequence of DNA

Mutation

25

Mutation cans be 3 things

neutral, beneficial, or harmful

26

agents that cause mutations

mutagens

27

occur in the absence of am mutagen

spontaneous mutations

28

causes thymine dimers

UV radiation
