Flashcards in Bacterial Genetics Deck (16):
1

Covalent ky closed dna circles which contain genetic information necessary for their own replication

Replicon

2

It gives resistance to antibiotics

Plasmids

3

Can integrate to the host chromosome

Episomes

4

What is the usually first amino acid in bacteria

F Methionine

5

This is a bacterial topoisomerase 2

Dna gyrase

6

This enzyme is responsible for proof reading

DNA polymerase 1

7

This enzyme is for repair

DNA polymerase 2

8

Unable to grow unless a certain nutrient is provided

Auxotroph

9

Base substitution in DNA causes replacement of 1 amino acid residue by another in a protein

Missense mutant

10

Substitution creates a stop codon and terminates the protein synthesis immaturely

Nonsense mutant

11

Redundancy of the genetic code

Silent mutant

12

This repair mechanism is due to photo deactivation

Light repair mechanism

13

Uses lack of methylation to recognize the new one

Mismatch repair mechanism

14

Uptake of unpackaged or free DNA and receive my must be competent

Transformation

15

Gram negative bacteria uses what kind of mechanism to transfer the gene

Sex pili for male
Tra gene

16

What are the types of the bacteriophage

Lytic or virulent

Temperate or Lysogenic
