During which phase of the cell cycle is the cell growing and preparing for cellular division?

• prophase

• interphase

• metaphase

• anaphase

Upon completion of the stage in the figure, what step will happen next?

• The homologous chromosomes will separate.

• The nuclear envelopes will reform and nucleoli will reappear.

• Bivalents will become aligned in the center of the cell.

• Spindle fibers will attach to homologous chromosomes.

What is the function of tRNA?

• Carries the correct amino acid to its correct codon.

• Makes amino acids needed at the ribosome.

• Coverts DNA to RNA>

• Links together the amino acids carried to the ribosome by mRNA.

Which best describes the interaction between DNA and RNA during protein synthesis?

• RNA carries the code to the nucleus where DNA translates the code into a protein.

• DNA travels to the cytoplasm while RNA remains in the nucleus.

• DNA travels to the ribosome where RNA translates the code into protein.

• RNA carries the code from DNA in the nucleus to the ribosome for protein synthesis.
