A mutation may result in:

• a stop codon before the protein is complete, making an incomplete protein
• no change in the protein
• a benefit to the organism
• all of the above
• none of the above

Why are scientists interested in using HeLa Cells?

• Scientists only need a few cells of any living thing to conduct research
• Scientists need a large supply of cells from anywhere to conduct research
• Scientists need a large supply of identical cells to be able to repeat experiments
• Scientists need cells that ignore mutations to conduct research

Which one of the following best describes a silent mutation?

• A mutation that changes the amino acid sequence, but so slightly that the protein still works.
• A mutation that doesn’t change the amino acid sequence of the resulting protein.
• A mutation that produces a completely nonfunctional protein
• All of the above
• None of the above

What are the structures in the nucleus of all cells that contain the genetic info?

• Chromatin
• Chromosomes
• Nucleotides
• Daughter cells

What is the end result of a frameshift mutation?

• the amino acids (protein) will only be different by one amino acid in the protein after the mutation.
• the amino acids (protein) will completely differ from the original protein after the mutation
• the amino acids (protein) will be exactly the same as the original protein after the mutation.

Transcribe DNA to mRNA and use the Codon Chart to determine the type of mutation and how it affects the amino acid sequence. Original DNA sequence: TAC GGA AGG AGA Mutated DNA sequence: TAC GGA GAG AGA

• Substitution mutation/ 3rd amino acid changes from Arg to Glu acid
• Substitution mutation/3rd amino acid changes from Ser to Leu
• Deletion mutation/3rd amino acid changes from Met to Pro
• None of the above

The main phase of the cell cycle that is where the cell spends most of its life span. It is mainly growing in size, the DNA is replicated and new organelles are formed.

• Mitosis
• Cytokinesis
• Interphase
• Cell Cycle

During G1 (Gap 1) phase, what is most likely happening to the cell?

• Growth and routine function
• Organelles copied, prepare for cell division
• DNA replication (DNA is copied)
