If you start with 5ng of template dna. how much would you have
after 10 cycles?

5.12μg of DNA

Explanation:

PCR is a method use to amplify DNA. It often require primers ( short sequence) nucleotides, heat stable polymerase enzymes, and thermocycler.

DNA strands are double by every cycle of PCR and it denoted by the formula 2^n  where n is the number of  cycle.

starting with 5ng,

the amount after 10 cycles = 2¹⁰ × 5 ng = 5.12μg of DNA

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?
