Protein Synthesis (Protein Synthesis)

What is protein synthesis?

• the making of RNA

• the making of proteins

• the taking apart of proteins

• the making of DNA

In RNA, A matches with 

• G

• U

• C

• T

In an RNA strand Thymine is replaced with?

• Uracil

• Gunine

• Cytosine

Only a portion of DNA, called a gene, is copied into RNA at one time.  

• False

• True

After the mRNA is formed, what happens?

• It moves out of the nucleus and into the cytoplasm.

• It binds permanently with DNA molecule.

• It disassembles and the process repeats.

• It moves out of the nucleus and then out of the cell.

What is the copying of mRNA from DNA?

What is the job of mRNA?

• To carry the amino acid to the ribosome

• To unzip the DNA so it can replicate

• To take the code out of the nucleus

How is mRNA read?

• Three strands at a time.

• A complete strand at a time.

• One base at a time

• Three bases at a time.

The 3 bases on mRNA is called a 

• codon

• anti codon

Why is tRNA called Transfer RNA?

• Because it is responsible for transferring the right amino acid to the ribosome to create the protein.

• Because it is responsible for transferring the protein out of the cell.

• Because it is responsible for transferring the protein building instructions to the ribosome.
