Answer and Explanation:
A restriction enzyme is a type of endonuclease enzyme that recognizes a specific short nucleotide sequences on the DNA and cuts the DNA only at palindromic sites. There are different types of restriction enzymes:
1. Type I restriction enzyme – It cuts at sites far from the recognition site and requires both ATP and S-adenosyl- L-methionine as cofactor to function.
2. Type II restriction enzymes – It cleaves at short-specific distances from the recognition site and mostly requires magnesium to function.
3. Type III restriction enzymes – It recognizes two separate non-palindromic sites and cleaves at 20–30 base pairs away from a recognition site. It requires both ATP and S-adenosyl-L-methionine .
The restriction enzymes cleave DNA sequences producing either sticky or blunt ends that can be ligated with other sequences.
Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing.

Cow’s milk contains low quantity
of some vitamins such as vitamin C, D and A than human breast milk. Also, Cow's
milk contains high amount of protein, and low amount of carbohydrates. One of
the proteins present in cow's milk is difficult for infants to digest and may
cause an allergic response making cow’s milk unsuitable for infants.
