How is genetic continuity (variation) ensured through meiosis in sexually reproducing organisms?

• By the random fertilization of gametes

• Through mitotic cell division

• Two divisions of the cell and the exchange of genetic material during crossing over

• Through uniform distribution of chromosomes

What genetic processes during meiosis contribute to diversity in gametes?

• Crossing over leading to the genetic diversity of gametes

• DNA replication and transcription

• Mitosis and cytokinesis

• Translation and protein folding

Identify common causes of mutations in cells.

• Insertion of a nucleotide into DNA, which changes the base sequence

• Ribosomes moving around the ER more

• More chlorophyll being produced as a result of more sunlight

• None of the above

• Only UVA increase mutation rates significantly

• Have no impact on mutation rates

• UVB decreases mutation rates

• Both

  increase rates

If one strand of DNA is "ATG CTG", what is its complementary strand (think about base pairing rules)?

• TAC GAC

• CAT GAC

• TAC CAG

• TAC GAT

What is the impact of X-rays on cellular DNA sequences (base-pairing)?

• They have no impact on the DNA sequence

• They could cause change in DNA sequence/

  mutations

• They enhance DNA replication

• They are essential for DNA repair
