Question

1. In DNA, the complementary bases are A-T and C-G, what is different about the complementary base pairing rules for RNA?

2. What amino acid is made from the mRNA codon GUA?

3. If the original DNA sequence is TAC-CCC-GAT-CGT, what would the complementary mRNA sequence be?

4. Using the mRNA sequence from number 3, what amino acids will be made from that sequence?

5. What are all the possible codons that would create the amino acid histidine (his)?

6. How many different codons are there that will create arginine (arg)?

7. If the amino acids joined together to make a protein are valine-proline-stop, what is one of the possible sequences of mRNA that could have created it?​

Answer 1

1. T is changed to U
2. Val
3. AUG GGG CUA
4. Met gly leu
5. CAU CAC
6. CGU CGC CGA CGG
7. GUC CCC UAA

These are my guesses but I’m 90% sure these are correct!!
