Flashcards in genetics 2 Deck (38):
1

integration

plasmid info in DNA now

2

transcriptions start here

promoter

3

frameshifting and a lot of amino acids change

insertion

4

silent mutation

change in nucleotide but not to amino acid; change in DNA but not protein

5

base substitution

mistake in replication, changes one nucleotide to another

6

mutation

small change in DNA sequence

7

homologous recombination

uptake of naked DNA and adding it to bacteria's DNA

8

tube connecting 2 bacteria

pilus

9

promoter is where

transcription starts

10

operator is where

repressor binds to turn gene off

11

one copy of chromosome, still double stranded

haploid

12

allolactose helps

inducer of repressor

13

where repressor binds to turn gene off

operator

14

gene for breaking lactose down

lac operon

15

just taking naked DNA

transformation

16

insertion

frameshifting; lots of amino acid changes

17

lactose

glucose and glactose held together by covalent bond

18

virus carries host DNA to different cell

transduction

19

small change in DNA sequence

mutation

20

plasmids themselves can transfer

horizonally

21

plasmid transfer

conjugation

22

lactose is turned into

allolactose

23

plasmid info in DNA now

integration

24

allolactose comes from

lactose

25

uptake of naked DNA to add to a live bacteria's DNA

homologous recombination

26

missense

change in both nucleotide and amino acid

27

inducer of repressor (takes repressor off operator)

allolactose

28

conjugation

plasmid transfer

29

haploid

one copy of chromosome (still double stranded)

30

mistake in replication, changes one nucleotide to another

base substitution

31

transduction

virus carries host DNA to different cell

32

change in both nucleotide and amino acid

missense

33

transcription occurs when

lactose is present and glucose is absent

34

change in nucleotide but not to amino acid; change in DNA but not protein

silent mutation

35

kinds of mutuations

base substitution
silent mutation
missense
nonsense
wild

36

nonsense mutation

change in nucleotide, inserts stop codon; translation stops

37

pilus

tube connecting 2 bacteria

38

change in nucleotide, inserts stop codon; translation stops

nonsense mutation
