Question

Now you will translate the amino acid sequence for the given tRNA strand. Remember that codons are 3 base pairs long.

1. AUG CAC UGU CCU UUC GCU GAC

2. GAG AUC UGG UUG GAA UCG

The following are pieces of mRNA. Give the DNA strand from which it was transcribed.

3. mRNA: G A G A U C U G G U U G G A A U C G

DNA   :

Using the following piece of DNA, give the mRNA molecule, and the amino acid sequence for which it codes.

DNA                 : A T A T A A A C G A G G A A A T T C C G G G C G

mRNA              :

tRNA                :

Amino acids    :

Use the mRNA sequence to find the DNA sequence and the amino acid sequence, the tRNA sequence and the aminoacids.

DNA                 :

mRNA              : A U G C C U A C A U G U G G U G U A A C C U U A

tRNA                :
