Use the following gene in protein synthesis?

Gene: TAG-GAC-CAT-TTT-AGC-CCC

mRNA: AUC-CUG-GUA-AAA-UCG-GGG

tRNA: UAG-GAC-CAU-UUU-AGC-CCC

Every 3 bases on the mRNA strand is a codon. A codon codes for a particular amino acid.

To identify the amino acids, you need to refer to a genetic code chart. http://www.google.com/search?q=genetic+code+chart&... Different charts are organized differently, but you can identify what amino acid each codon codes for.

For example, AUC codes for isolucine. CUG codes for leucine.

Remember that mRNA is a copy of the gene. And each tRNA is complementary to the mRNA codon. The bases of the tRNA is called the anticodon. And each tRNA transfers the specified amino acid to the ribosome.

Also remember that in RNA, uracil (U) replaces thymine (T).

Hope this helps.

Bad question.

Your instructor needs to indicate sense and directionality of the given strand.

The "show the tRNA" part is totally bogus since a tRNA is so much more than just its anticodon.

If you want to give an answer that is wrong but will be marked right, then go with what Sean did.

==> Your online course isn't very good. If you can find the author of the problem set, have him or her fix this problem.

check these links out i hope they'll help you.

they helped me for my tests :)

Do try the question after watching these, im sure you'll get it.

mRNA: AUCCUGGUAAAAUCGGGG (you basically have to do base pairing keeping in mind that RNA contains Uracil instead of Thymine)

tRNA : this will be different for every codon (3 base set) on the mRNA

amino acids: this will be decided according to the codons

to make it easier, lets break the mRNA sequence into sets of three bases (codon)

AUC CUG GUA AAA UCG GGG

now use the codon table to decide the amino acids (search on google images for one if you dont have one)

Ile leu val lys ser gly

(isoleucine, leucine, valine, lysine, serine, glycine )
