single stranded DNA phage plus single-stranded RNA phage

Question 1

a + single strand DNA phage ?

Answer 1

Phage ΦX174(same strand as mRNA)

Question 2

To perfom dsDNA,replicative form we need?

Answer 2

synthezise the minus strand

Question 3

first step of replication by rolling circle ?

Answer 3

Replication form DNA is nicked by gene A protein

Question 4

second step of rolling circle?

Answer 4

new + strand begins synthesis

Question 5

third step of rolling circle ?

Answer 5

continued extension or original + strand with synthesis of new strand

Question 6

fourth step of rolling circle?

Answer 6

one revolution complete and one progeny virus made

Question 7

What the results of the rolling circle?

Answer 7

• • strand

- -/+ strand

Question 8

what can we do with the + strand?

Answer 8

refaire le meme cycle

Question 9

Single-stranded RNa phage who is one?

Answer 9

phage MS2

Question 10

phage MS2 is what?

Answer 10

plus strand RNA phage

Question 11

in single-stranded RNA phage the genome is used first?

Answer 11

as an mRNA(translation direct)

Question 12

the genome used as first mRNA?

Answer 12

directs the synthesis of an RNA replicase(RNA-dependent RNA polymerase) and other viral proteins

Question 13

The synthesis of RNA replicase is not performed by?

Answer 13

The host (on ne passe pas de - a + strand)

Question 14

the RNA replicase synthesizes?

Answer 14

a minus strand RNA t

Question 15

the minus strand RNA is used to produce?

Answer 15

• additional mRNA

- additional copies of the genome (+ strand) for the production of new virion

Question 16

la translation direct donne quoi?

Answer 16

viral proteins
