A sample of DNA is taken from blood of saliva. PCR makes lots of copies, or amplifies the DNA. We then add restriction enzymes to cut the DNA at palindrome sequences. We then run the DNA through gel Elecrophoresis. Each person has unique short tandem repeats that cause a unique number of cuts by the restriction enzyme. These cuts are separated by size on gel electrophoresis, so no two people have the exact same pattern. We can compare individuals banding patterns to what is found at a crime scene, taken in previous samples, in a baby, and the sample that matches all the banding patterns will be the individual.
One result is that the ovaries would be unable to produce oocytes (eggs) for fertilization hence the woman would be unable to conceive. Another is that the woman would have an abnormal menstrual cycle due to abnormalities in the production of estrogen and progesterone by the ovary.
<span>Hemostasis is the process of the body that seals blood vessels that rupture. The process is basically starts with an injury, then vascular spasm, platelet plug formation and then coagulation.
During blood clot formation, blood is transformed into solid gel at site of damage, where plasma fibrinogen is converted into loose fibrin molecules, which bind together to form mesh. Platelets and blood cells get trapped here by the fibrin strands, which produces a clot. This part of the clot formation is called coagulation.

Answer:
The lectin pathway or lectin complement pathway is a type of cascade reaction in the complement system, similar in structure to the classical complement pathway, in that, after activation, it proceeds through the action of C4 and C2 to produce activated complement proteins further down the cascade.
Evolution is all about the
process of inheriting characteristics within a population change over
generation.
Only inherited traits
differences that can be passed on are acted upon evolution.
<span>In the study, the humans
select desirable traits that can be passed from one generation to another.</span>
