Hey, just making up a c in honors bio and cant find any notes or anything on this.
help


1.What would the complementary mRNA strand be for this gene?

ATC CGT TAT GTA CCA


a TAG GCA ATA CAT GGT
b GAC GAC CCA CUC TUA
c UAG GCA AUA CAU GGU
d UAC CCA AUA GAU CCU


2. What would the complementary strand of DNA be of this gene?

ATC CGT TAT GTA CCA


a TAC CGA TAA GAT TTA
b TAG GCA ATA CAT GGT
c GAT GCA ATA GAT AAC
d UAG GCA AUA CAU GGU

If A is in DNA, the complimentary DNA block is T (vice-versa).
T is replaced by uracil (U) in mRNA, so the complimentary block of A in a strand of DNA will be U in mRNA (vice-versa).
G and C are complimentary, and are in both mRNA and DNA.
So let's decode.
1.ATC CGT TAT GTA CCA in strand of DNA

= UAG GCA AUA CAU GGU in opposite strand of mRNA.

2.ATC CGT TAT GTA CCA in a strand of DNA

= TAG GCA ATA CAT GGT in opposite strand of mRNA.

So, 1 is C, and 2 is B.
