eukaryotic cell reproduction

Answer 30

sexual reproduction

Question 31

parts of a virus

Answer 31

capsid, nucleic acid, sheath, tail fibre

Question 32

how to classify viruses

Answer 32

size and shape of capsid, and the disease they cause

Question 33

virus replication

Answer 33

requires a host cell. lytic and lysogenic

Question 34

lytic cycle

Answer 34

bacteriophage attaches itself to bacterial cell and injects nucleic acid. it uses the cell's ribosomes to make up virus proteins that break up the cell's dna. the viral nucleic acid takes over and directs the production of new virus proteins and nucleic acid. they assemble into new viruses and then lead to the explosion of the cell.

Question 35

lysogenic cycle

Answer 35

once the phage dna is inside the cell it isn't immediately copied or expressed to make proteins. instead, it is integrated into the chromosome. cell division then occurs and makes many cells with the viral prophage.

Question 36

what is the difference between the lytic and lysogenic cycle

Answer 36

the lytic cycle leads to the new viruses bursting from the cell and killing it. the lysogenic cycle effects may not be immediate.

Question 37

retroviruses

Answer 37

enter and exit cell without causing it to burst

Question 38

pilia

Answer 38

hair-like structures that help bacteria attach to surfaces and other bacteria
