The following portion of DNA is in the template DNA strand:

Question

-TGT-GGG-GTT-ATT-

a. What is the corresponding mRNA section?

b. What are the anticodons of the tRNAs?

c. What amino acids will be placed in the peptide chain?

Answer 2

a. -aca-ccc-caa-uaa

b. -ugu-ggg-guu-auu

c. cys-gly-val-ileu

Answer 3

a.) -ACA-CCC-CAA-UAA-    --> Base paring rules for mRNA production are the same as for DNA construction; A goes with T, C goes with G. The only difference is that T (thymine) is replaced with its unmethlyated precursor in RNA; Uracil (U).

b.) The anitcodons of the tRNA are the respective corresponding bases to the mRNA codon bases (essentially they read the same as the DNA template strand with the exception that T's are now U's.

-UGU-GGG-GUU-AUU-

c.) For this question you need a codon table. Here is a link to one: http://citnews.unl.edu/croptechnology/le...

look up the mRNA codons to get the amino acid which corresponds to it.

-Thr-Pro-Gln-(non-coding codon, aka stop codon)-
