There are three websites for you to investigate that will teach you about base
pairing and making proteins. Click through them to help your understanding of
each process.

2. What is the function of mRNA?
The function of mRNA is to carry the genetic information copied from DNA.

Th
3. What is the function of tRNA?
sh
The function of tRNA is to decode mRNA sequences into a protein.
4. In what part of the cell is a protein molecule made?
Protein molecules are made in ribosomes.

, 5. Why do you think there are equal amounts of cytosine and guanine, and equal
amounts of adenine and thymine in the DNA of a cell?
I think the bases have equal amounts of each because they mirror are linked with one
another, creating a message and eventually being translated.
6. What do you think would happen if there was an extra base deleted from the mRNA
code of a protein?
An extra base deleted or added would change the coding of the mRNA and would cause a
translation of a different protein, one that may be nonfunctional.

There are base pairing rules for writing complimentary DNA strands for a given strand:
o
A pairs with T; C pairs with G.
aC s
vi y re
In RNA, A pairs with U, instead of T.
Write the complementary DNA strand for the given DNA. This is replication.
