Bio A- Quiz 1: Protein Synthesis

What is the function of mRNA?

• provide energy for the duplication of cells
• stores food material for keeping cells alive
• preventing mutations
• carrying the gentic message

What part of protein synthesis does this diagram represent, notice it is carrying something at the end?

• mRNA

• tRNA

• rRNA

• RNA

Why can genes from one organism like a bacteria be inserted into a human genome?

• both organisms are classifies in the same kingdom
• the genome of both organisms is identical
• the genetic code is universal to all living things
• microorganisms are typically lower level prokaryotes while humans are higher level eukaryotes

The DNA sequence ATCAGCGCTGGC is part of a gene. how many amino acids are coded for by this message?

• 4
• 8
• 12
• 20

Which describes a role that ribosomes assume in the production of proteins?

• transports nutrients into and out of the cell
• produces ATP for the cell to use
• translates mRNA into specific amino acid chain
• rids the cell of leftover amino acids once proteins have been synthesized

What is the purpose of this process?

• to create polypeptides and, eventually proteins for gene expression
• to copy original DNA strands into complimentary strands
• to generate and release ATP
• to regulate the internal environment of the cell

Which type of nucleic acid is like a protein synthesis factory?

• mRNA
• tRNA
• rRNA
• RNA

The process of making an mRNA strand from a DNA template is called

• Replication
• Transcription
• Translation
• Protein Synthesis

The process of using an mRNA to make a protein is called

• Replication
• Transcription
• Translation
• Cell Division

Transcription takes place in the 

• cytoplasm
• chloroplast
• nucleus
• mitochondria
