binary fission and virus replication

Question 1

explain the process of binary fission

Answer 1

1. cell growth
2. dna replication - the coiled dna replicates once but the plasmids replicate several times
3. the coiled dna moves to either end of the cell and the plasmids are randomly distributed
4. the cell membrane breaks down and a new cell forms between the dna
5. the cytoplasm splits resulting in 2 daughter cells

Question 2

what is the genetic information like in each new daughter cell made in binary fission

Answer 2

each one will have 1 strand of DNA, however they can different number of plasmids each

Question 3

explain how virus replication works

Answer 3

1. they use there attachment proteins to bind to the complimentary proteins on the hosts cells surface
2. as a result of complimentary bindings, only one certain virus can infect a certain cell
3. they inject their DNA or RNA into the host cell which replicates it
4. the replicated viruses leave the host cell via the membrane

Question 4

is binary fission sexual or asexual

Answer 4

asexual

Question 5

what does binary fission produce

Answer 5

2 genetically identical daughter cells
