Which general formula can be used to identify carbohydrates? A. Cx(H2O)y B .Cx(HO2)y C. C2(HxO)y D. Cx(HyO)2

 A.  Cx(H2O)y

Explanation:

There  are  three  major  types  of  carbohydrates.  Monosaccharides,polysaccharides  and  disaccharides  and  the   the  main  fomula  of  Cabohydrates  is Cx(H2O)y

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
