What’s the correct mRNA sequence from the DNA strand: TAC GCC CGA ATC A. ATG CCG GCU TAG

B. AUG GCC GCU UAG

C. AUG CGG GCU UAG

D. AUG CCG GCT UAG

E. ATG CCG CGT TAG

C. AUG CGG GCU UAG

Explanation:

This works the same as a normal DNA strand, A=T, C=G, except for one difference. Thymine is not an mRNA base, instead it is Uracil. Therefore, if there is an A, you would typically replace it with a T, but for mRNA you will replace it with a U. Keep in mind you will still replace the T in the DNA strand with an A in the mRNA strand :)

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
