Protein Synthesis

How many possible codons exist in the genetic code?

• 3

• 20

• 46

• 64

The two processes of protein synthesis are

• gene expression and protein expression.

• transcription and translation.

• replication and translation.

• transcription and the genetic code.

For protein synthesis to initiate,

• RNA polymerase must bind to a gene's promoter.

• nucleotides must be added to the mRNA strand.

• the mRNA must be flow from the nucleus to the cytoplasm.

• the tRNA and rRNA molecules must be made.

In RNA, Uracil pairs with ______. 

• cytosine
• adenine
• guanine
• thymine

The process to go from DNA to mRNA is _______

• translation
• transcription
• replication

The process to go from mRNA to a protein is called ____

• rRNA
• replication
• translation

Choose the nucleotide sequence of the RNA strand that would be complementary to the following strand: 
GTAGTCA

• UATUAGA
• ACGACTG
• CAUCAGU
• CATCAGT

The main function of tRNA is to...

• carry a message that, when translated, forms proteins
• form a portion of ribosomes
• string together complementary RNA and DNA strands
• bring amino acids from the cytoplasm to the ribosomes
