Protein Synthesis

Which organelle is the location where protein is made?

• Ribosome

• Nucleus

• Cytoplasm

• Nucleotide

During transcription, this type of ribonucleic acid is responsible for copying the DNA and brining it out of the nucleus.

• tRNA

• mRNA

• rRNA

• dRNA

What is the term for a three-nucleotide sequence that codes for an amino acid?

• base

• codon

• amine

• serine

Why is it important for a cell in Henry's body to regulate the expression of genes involved in protein synthesis?

• To ensure that proteins are only synthesized when needed

• To prevent mRNA from leaving the nucleus

• To increase the mutation rate in DNA

• To make the process of transcription faster

DOK Level 2: Skill/Concept

How does the genetic code determine the sequence of amino acids in a protein?

• By the number of nucleotides in DNA

• By the sequence of sugars in mRNA

• By the order of nitrogenous bases in mRNA

• By the structure of the ribosome

In the process of building a protein in a cell, what role does tRNA play?

• Carries amino acids to the ribosome

• Transfers genetic code from the nucleus

• Forms the structure of the ribosome

• Unzips the DNA strand

During translation, what does the mRNA do?

• It replicates itself.

• It folds into a protein.

• It serves as a template for protein synthesis.

• It exits the cell.

How does the genetic code ensure that proteins are made accurately in all cells of Michael's body?

• By changing the sequence of amino acids

• By allowing multiple codons for a single amino acid

• By using a different code for each cell type

• By using a universal code shared by all organisms
