D) RNA

QUESTION 16 What is true about the relationship of DNA and chromosomes? A) Chromosomes manufacture the proteins that build the DNA molecule. B)Chromosomes unwind the DNA molecule so that sections can be made into genes by RNA.
C) Various nucleotide sequences of DNA code for different chromosomes. D) Each chromosome contains a single, tightly wound DNA.

QUESTION 18
What role does mRNA play in the delivery of genetic code information? A) mRNA reads the code from one gene on a chromosome and then delivers that message to rRNA.
B) mRNA copies the code from one segment of DNA that represents one gene and then carries it out of the nucleus to a ribosome.
C) mRNA transports a gene segment to tRNA where the code is read and an amino acid is made.
D) mRNA collects the DNA from all of the chromosome and duplicates it using nucleotide base pairs.

QUESTION 22
Which statement describes the chromosomes by the end of anaphase of mitosis? A) The chromosomes reach opposite sides of the cell and begin to be incorporated into two new nuclei.
B) The chromosomes have coiled and become more compact.
C) The chromosome pairs collect in a line across the middle of the cell. D) The chromosomes separate at the centromere and begin to move apart.

B) anaphase II
C) telophase I
D) telophase II

QUESTION 24

What determines the similarities in anatomical features among organisms?

D) Genes and chromosomes

QUESTION 14

What controls the cell's ultimate production of proteins?

B) DNA

QUESTION 16

What is true about the relationship of DNA and chromosomes?

A) Chromosomes manufacture the proteins that build the DNA molecule.

Chromosomes carry genetic information in a molecule called DNA

QUESTION 18

What role does mRNA play in the delivery of genetic code information?

B) mRNA copies the code from one segment of DNA that represents one gene and then carries it out of the nucleus to a ribosome.

Messenger RNA (mRNA) carries the genetic information copied from DNA in the form of a series of three-basecode “words,” each of which specifies a particular amino acid.

QUESTION 19

A snapping turtle has 52 chromosomes. Which statement correctly compares the number of chromosomes in a body cell with that in a sex cell of a snapping turtle?

A) The body cell has 2n; the sex cell has 1n.

QUESTION 20

Which of these statements is true?

C) Meiosis involves two cycles of cell division.

QUESTION 21

Which phase of cell division includes the pinching off or cleaving of the cell into two new cells?

D) telophase

Telophase refers to the last stage of the mitosis in which the cellular content of the parent cell is divided equally into the two daughter cells.

QUESTION 22

Which statement describes the chromosomes by the end of anaphase of mitosis?

A) The chromosomes reach opposite sides of the cell and begin to be incorporated into two new nuclei.

QUESTION 23

Which phase of cell division results in the formation of four new haploid cells?

D) telophase II

QUESTION 24

Which statement describes the chromosomes by the end of telophase II of meiosis?

D) The chromosomes of each of two diploid cells reach opposite sides of the cell, incorporating into two haploid nuclei.
