Use “Transcription Animation” on my webpage in order to answer these questions.
1) What are the three regions of a gene? And is the function of each region?
2) What molecule “unwinds” the DNA during transcription and acts to add free
floating nucleotides?
3) What molecule is synthesized during transcription?
4) After the mRNA strand is synthesized and travels to the cytoplasm, what happens
to the “unzipped” DNA strand in the nucleus?
Translation:

5) What is the first step of protein synthesis called?
6) What is the second step of protein synthesis called? What happens during this
step?
7) What three nitrogen bases make up the “start codon”? ___ ___ ___
8) What type of chemical bond joins together the amino acids in the chain that is
produced during translation?
Use your notes, GOOGLE, and/or your own knowledge to answer the following questions:
9) What is the first amino acid on the chain made during any act of translation?
