• storing amino acids used for protein synthesis
• storing information used for protein synthesis
• storing electrical charge for protein synthesis

What is seen in this picture?

• A strand of DNA
• A strand of RNA
• A lipid
• A carbohydrate

What is the main importance of DNA replication?

• to ensure daughter cells have a complete copy of DNA
• to create genetic variation
• to produce sex cells that are haploid
• to allow prokaryotic cells to divide

Which enzyme is responsible for breaking hydrogen bonds between nitrogen bases during DNA replication?

• DNA Polymerase
• Ligase
• Helicase
• RNA Polymerase

If you take a drug that prevents tumor growth by blocking DNA replication, what other cells will the drug affect?

• None, just the tumor cells
• Only the cells near the tumor cells
• Just your stomach cells, where the drug is digested
• All other cells that need to divide

According to the chart, what amino acids are coded for by the mRNA strand AUGGGUACA

What is the function of DNA in protein synthesis?

• provides genetic material for offspring
• provides a template
• carries the genetic message to the ribosome
• directly regulates what enters and leaves the cells

In what stage of protein synthesis are DNA and RNA most closely interacting?

• Translation
• Transcription

What type of gene relationship controls traits that are affected by many different proteins?

• Polygenic
