Protein Synthesis Unit Overview

Which of the following are part of translation?

• bases are linked to form an mRNA chain

• DNA is unzipped

• ribosome adds tRNA to the mRNA

• tRNA is released and leave the ribosome

How many nucleotides code for 1 amino acid?

How can a mutation in the DNA sequence result in NO change to the protein that is made?

• There are multiple codons that can code for the same amino acid and result in the same protein

• There is always a change in the protein when a mutation occurs

• Only the mRNA is used in protein synthesis so a mutation in the DNA would have no effect on the protein

In RNA, Uracil pairs with ______. 

• cytosine
• adenine
• guanine
• thymine

When these bond together with peptide bonds, they form a protein.

Which organelle is the location where protein is made?

• Ribosome

• Nucleus

• Cytoplasm

• Nucleotide

The mRNA leaves the ________ to find the ribosome to make proteins.

What part of protein synthesis does this diagram represent?

What is the first step in protein synthesis?

• transcription

• translation

What brings the amino acids to the ribosome to assemble a protein?
