Why do genes only make up a small percentage of DNA? We only use a small portion of DNA, because there aren't that many unique proteins.
It reduces the chances of genes being damaged.
It prevents cells from accidentally making the wrong protein.
The extra DNA will eventually be turned into genes as organisms evolve.

Which type of bacterial reproduction is depicted in the diagram?

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
