Question 1

Type of mutation where a single base is replace within another base

Answer 1

base substitution

Question 2

type of mutation where a base substitution results in amino acid substitution

Answer 2

missense

Question 3

true or false If transcription is repressed, then translation does not occur?

Answer 3

True. If transcription is repressed, it means that RNA polymerase is prevented from transcribing the DNA into mRNA.

Question 4

Repression turns genes on.

Answer 4

False they are turned off or their expression is reduced.

Question 5

type of mutation where a base substitution codes for a stop codon

Answer 5

nonsense

Question 6

Type of mutation when a base is inserted or deleted

Answer 6

frameshift

Question 7

Answer 7

operator

promoter

Question 8

true or false An operator in a operon starts and stops transcription.

Answer 8

True

Question 9

Lactose

Answer 9

can be broken down into glucose and galactose
requires beta galactosidase to be split

Question 10

true or falase If the E.coli is inoculated into lactose, then beta galactosidase can be produced.

Answer 10

True

Question 11

The inducer in the lac operon is

Answer 11

allolactose

Question 12

Type of plasmid that transfers antibiotic resistance

Answer 12

R factor

Question 13

Mutagens

Answer 13

can be radiation such as UV light
can be chemicals such as food preservatives
substance that causes mutations

Question 14

true or false At the end of conjugation, both cells contain the plasmid (F+).

Answer 14

True

Question 15

Type of genetic transfer where naked DNA is transferred to a bacteria

Answer 15

transformation

Question 16

Techniques that manipulate DNA of an organism

Answer 16

genetic engineering

Question 17

Type of genetic transfer that requires a plasmid and cell to cell contact

Answer 17

conjugation

Question 18

Type of genetic transfer uses a bacteriophage to transfer DNA

Answer 18

transduction

Question 19

Procedure that amplifies and makes more DNA using Thermus aquaticus

Answer 19

PCR

Question 20

Type of genetic transfer where segments of DNA move from one region to another

Answer 20

transposons

Question 21

Type of mutation where a single base is replace within another base

Answer 21

base substitution

Question 22

Plasmids Are

Answer 22

replication separately from chromosomal DNA
enhance pathogenicity
are circular pieces of DNA

Question 23

Gel Electrophoresis

Answer 23

uses electrical currect to separate DNA molecules
uses PCR to obtain amplified data
the smaller the DNA travels that farther they travel

Question 24

Gene editing tool that locates a specific DNA sequence and cuts it out

Answer 24

CRISPR-Cas 0

Question 25

CRISPR-Cas 9 can be used to

Answer 25

fix human genetic diseases modify plants modify livestock

Question 26

Type of plasmid used in conjugation

Answer 26

F factor

Answer 27

gene therapy
