A few biology questions.. please please help!?

8. The G2 checkpoint prevents the cell cycle from continuing until ____.
A. DNA is completely replicated
B. damage to DNA can be repaired
C. replicated DNA is separated
D. orgnaelles have been duplicated.
E. DNA is completely replicated AND damage to DNA can be repaired.

11. How do the daughter cells at the end of mitosis and cytokinesis compare to their parent cell when it was in G1 of the cell cycle.
A. the daughter cells have half the amount of cytoplasm and half the amount of DNA
B. the daughter cells have half the number of chormosomes and half the amount of DNA
C. the daughter cells have the same number of chormosomes and half the amount of DNA
D. the daughter cells have the same number of chormosomes and the same amount of DNA
E. the daughter cells have half the same number chormosomes and twice the amount of DNA

30. Which of the following is not a fucntion of meiosis?
A. Cause an organism to grow
B. create genetic variability.
C. reduce the chromosome number in gametes
D. keep chromosome number constant from one generation to the next.
E. produce gametes.

32. A tetrad consists of four homologous chromosomes with one chromatid each.
A. True
B. False.

35. The filled-in squares of a Punnett square represent
A. the nubmers of individuals with each version of a trait.
B. All possible combinations of gametes based on a cross between the two parents.
C. An exact ratio that must always occur when the same parents have four offspring.
D. examples of some of the offspring that can arise from a one-trait cross.
E. the gametes from one parent.

36. Parents with the dominant phenotype cannot have offspring with the recessive phenotype.
A. true because hte dominant gene must be passed down from each parent.
B. True because at lease one dominant gene will be passed down from each parent.
C. False because one parent could carry the recessive allele.
D. False bveause both parents could carry the recessive allele.
E. True because both parents have the dominant allele.

38. Alleles are
A. dominant traits
B. Recessive traits
C. 2 versions of the same trait
D. alternate versions of the same trait.
E. Exact copies of the same trait.

55. DNA replication is called semiconservative because
A. one of the two resulting DNA molecules is new.
B. the two resulting DNA molecules each have one new DNA strand and one old strand from the original DNA molecule
C. both of the resulting DNA molecules are composed of new strands of nucleotides.
D. no extra nucleotides are incoporated into the replicated DNA molecules.
E. The sequence of nucleotides in one strand is conserved, whereas the new DNA molecule consists of a unique sequence of nucleotides.

58. Which process requries the aprticaption of all three types of RNA
A. transcription
B. Translation
C. RNA processing
D. Replication
E. complementary base pairing

61. DNA replciation makes a(n) ____ copy of the DNa, while transcription makes a(n) ____ copy of the DNA.
A. mRNA; DNA
B. DNA; mRNA
C. DNA; tRNA
D. mRNA; tRNA
E. mRNA; rRNA

63. the two DNA strands must be separated before DNA replication or transcription can occur.
A. True.
B. False

Thanks for all your help, I just could not find out the answers for these questions!!
