A mutation occurs in human skin cell. What would make this mutation a cause of concern?

• This type of mutation will change cell type

• The individual's offspring will inherit the mutation

• It can cause overproduction of abnormal cells within the individual's body

• It can prevent the organism from producing normal muscle cell

Which amino acid would result from CUC-AAG-UGC-UUC?

• Leucine-Leucine-Cysteine-Leucine

• Leucine-Lysine-Cysteine-Phenylalanine

• Glutamic acid-Phenylalanine-Threonine-Lysine

• Leucine-Arginine-Serine-Phenylalanine

Which statement best explains the process?

• Process X result in cell that have more genetic variation than those produced in Process Z

• Process Z result in cell that have more genetic variation than those produced in Process X

• Process X result in 1 cell that has the exact same DNA as the parent cell, Process Z result in 2 cells that has the exact same DNA as the parent cell

• Process X result in 1 cell that has the exact same DNA as the parent cell, Process Z result in 2 cells that have different DNA from the parent cell

A nuclear membrane with pores surround a cell's nucleus. How would a nucleus that lacks pores affect its function in the cell?

• mRNA would not be able to leave the nucleus to provide the code to make proteins

• mRNA would not be able to leave the nucleus to make carbohydrates

• DNA would not be able to leave the nucleus to provide the code to make proteins

• DNA would not be able to replicate or leave the nucleus
