Which process is shown?

• diffusion

• repiration

• recombination

• translation

Translation is crucial to the process of making proteins. Which statement best describes what takes place during translation?

• A copy of chromosomal DNA is created 

• Information in mRNA is converted into a sequence of amino acids in a protein 

• A RNA copy of a DNA strand is made.
  

• Instructions from DNA in the nucleus are brought to the cytoplasm

Which of the following describes RNA?

• RNA is usually double-stranded and contains the base thymine

• RNA is usually single-stranded and contains the base uracil

• RNA is longer than DNA and uses five bases to encode information

• RNA is made in the nucleus of eukaryotic cells and stays there to carry out its functions

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

Which process converts mRNA into a protein?

• Transcription

• Translation

• Replication

• Mutation

Which process converts mRNA into a sequence of amino acids?

• Replication

• Transcription

• Translation

• Mutation

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

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 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
