A strain of bacteriophages was grown in BrdU. BrdU is a base analog, that when incorporated into DNA, causes the DNA to fluoresce yellow. Another culture of the bacteriophage strain was grown in media containing cysteine (an amino acid) linked to a red fluorescent molecule. Each strain of bacteriophage was allowed to infect unlabeled cells. Follow the patterns of fluorescence through infection. How would this experiment help prove that DNA is the genetic material

Twins are born minutes apart, not a year apart. fraternal twins are no more closely related genetically than ordinary siblings born a year apart. they just happen to be born at the same time. identical twins result from a single fertilized egg dividing and separating early in gestation. although identical twins are more similar to each other than other siblings, there is some research to suggest they are not 100% the same. you and your brother share very similar dna because you have the same parents, and you look the same. i'll bet you resemble one or both of your parents, and likely a grandparent or two as well.
