How is homologous recombination for DNA repair different from recombination in meiosis? Choose all correct answers.
a. HR in DNA repair requires a double-strand break, but meiotic recombination does not.
b. HR in DNA repair requires strand invasion, but meiotic recombination does not.
c. HR in DNA repair results in identical chromosomes. Meiotic recombination results in changes to the DNA sequence of the "repaired" chromosomes.
d. HR in DNA repair uses a newly synthesized identical chromosome as a template. Meiotic recombination uses a homologous chromosome as a template.

Which types of mutations cause (1 word)
a. Increase amount of genetic material in particular chromosome
b increase amount of genetic material in all chromosomes
c decreased amount of generic material in particular chromsomes
d change to position of dna sequence in singular chromosome without changing the amount of genetic material
e move dna from one chromosome to non homologous chromosome
