Plz ! what sex is the person who has the karyotype described in steps 3-4? how do you know? in what ways are the mutations described in steps 5-6 and 7-8 different from those described in steps 9-10 and 11-12? in steps 11-12, you saw that cystic fibrosis is caused when specific sections of both copies of chromosome 8 are deleted. on the basis of this information, do you think cystic fibrosis is a dominant or recessive trait? do all mutations result in negative effects?

I can’t help you with the first two questions, as I do not have a reference, but I can help you with the last two. Cystic fibrosis is a recessive trait. It is caused when specific sections of both copies of chromosome 8 are deleted, which in other words mean that it is not a sex-linked disorder because it isn’t inherited from the mother and father of the offspring.

No, all mutations are not bad. Only a small amount of mutations cause genetic disorder. Some in fact are good mutations. There is actually one mutation that is found roughly in 10% of Europeans which affects the CCR5 protein and it prevents HIV from entering the cell!

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
