Answer:

The polymerase chain reaction is a method used to produce millions of copies of particular DNA.

DNA sequences are amplified to generate many copies of a specific DNA segment.

Explanation:

polymerase chain reaction is used to produce a million copies of DNA by amplifying the  DNA sequences exponentially.

PCR method was developed in 1983 by Kary Mullis.

A polymerase chain reaction occurs in three main steps.

  • Denaturing: In this step, double-strand template DNA is separated into two single strands by heating.
  • Annealing: DNA primers get attach to the DNA template when the temperature is lower.
  • Extending: with the help of the Taq polymerase new strand is synthesis which is complementary to the template DNA.

thus polymerase chain reaction is used to produce many copies of DNA of specific region of DNA.

Explain why scientirsts concluded that the instructions for species characteristics were carried in DNA.
siniylev [52]

Answer:

Explanation:

Deoxyribonucleic acid is said to contain instruction for species characteristics because it carries the information that characterize an individual.

DNA are made up of Nitrogenous bases that are unique codes specify by an individual and no two person has the same the DNA.

Genes are genetic information or instruction that specify an individual. it is located in the chromosome in the nucleus. DNA contains gene which helps to make molecules called proteins. It is the basis of all inheritance and the expression of the gene is what produces the phenotype that is visible.
