How DNA helps make you you

DNA Function

Your development and survival depend on… which proteins your cells produce, how many are produced, and… when they are produced.

Random chance and your life experiences determine the rest

DNA Function Review

1. What are the 3 parts of a nucleotide?

2. What are the 4 bases found in DNA?A. Which ones are complementary?

B. Which base is found only in RNA?

3. Transcribe the following DNA strand:

TACCTTGGATCGAAACCT

4. What sequence of amino acids would be produced from the RNA made in #3?
