Answer:

Explanation:

This is known as the RNA world hypothesis. Scientists favor RNA over DNA as the first genetic molecule for several reasons. Perhaps the most important is that RNA can, in addition to carrying information, act as a catalyst. ... A catalytic RNA could, potentially, catalyze a chemical reaction to copy itself.

First you need to convert the template strand (what you have) to the coding strand.

So using the following guide convert the given letters:

A->T

T->A

G->C

C->G

This will now encode your strand as:

CCTGTAAAAGTGGCA

Break these into three letter chunks:

CCT GTA AAA GTG GCA

Your teacher should either give you a guide or tell you which ones to memorize, but you could also use the following chart to figure out which amino acids will be synthesized:

Use the chart underneath The Genetic Code(DNA) to figure out what matches where.

You will then get the following:

1. Proline (cct)

2. Valine (gta)

3. Lysine (aaa)

4. Valine (gtg)

5. Alanine (gca)

Also remember that if you see a T in your original strand it could also be interpreted as a U. You can always check your answers using this handy online app: http://www.geneseo.edu/~eshamb/php/dna.php
