Thrombin catalyzes the activation of these molecules present in plasma. 2. : Makes up most of plasma protein. 3. : The major contributor to plasma osmotic pressure. 4. : Forms the structural framework of a blood clot.

1. when there is a cut, the surface area of the skin becomes rough which activates the Thrombin, that catalyzes the activation of fibrinogen present in plasma.

2. albumin contributes mostly of making plasma protein

3. albumin contributes the major portion to the osmotic pressure of plasma.

4. fibrinogen mainly forms the structural framework of a blood clot during blood coagulation.

ans.

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.'
