CBAS LOL UTC - DNA replication, protein synthesis, meiosis

Which statement best describes what happens during DNA replication?

• DNA is copied.

• DNA synthesizes a protein.

• DNA is used to create mRNA.

• DNA transports genetic information to the cell.

Which term refers to different types of RNA working together to make a protein?

• translation

• replication

• expression

• transcription

Which is best indicated by #6?

• replication

• translation

• transcription

• protein synthesis

Which is best indicated by #3?

• replication

• translation

• transcription

• protein synthesis

Which is best identifies #2?

• DNA

• rRNA

• mRNA

• tRNA

Which process is happening at #3?

• Codons are being decoded.

• Amino acids are being sequenced to form proteins.

• DNA is being copied into RNA.

• The cell is dividing into two daughter cells.

A step in DNA replication is the breaking of hydrogen bonds between bases of the connected strands of DNA. (Unzipping the DNA)

What is the next step in DNA replication?

• New hydrogen bonds form between the bases.

• The cell uses the bases for energy.

• An RNA primer is added to each strand.

• The DNA splits into thousands of pieces.

Which statement about translation is true?

• DNA determines mRNA's base sequence in the process of translation.

• Translation requires mRNA, tRNA, and rRNA to perform protein synthesis.

• Translation combines ribosomes and amino acids during RNA synthesis.

• DNA polymerase links together amino acids and completes translation.

What is the function of interphase in cellular reproduction?

• pinching the membrane in half to form two identical cells

• allowing the cell to grow and prepare for division

• moving chromosomes to opposite sides of the cell

• shrinking the cell to allow room for newly created cells

Which is true of mitosis?

• Mitosis consists of three phases.

• Mitosis is responsible for the formation of sex cells.

• Mitosis causes cells to swell to ten times their normal size.

• Mitosis results in two identical daughter cells.
