A: ' 5’ GGATCC 3’ ' is a DNA sequence with one strand of a restriction enzyme recognition sequence.
A restriction enzyme refers to a DNA-cutting enzyme that recognizes particular sites in DNA. Various restriction enzymes create staggered cuts at or near their recognition sites, making ends with a single-stranded overhang. In case when two DNA molecules have matching ends, the enzyme DNA ligase can be used to join them. The restriction endonuclease enzyme (EcoRI) recognizes the 5'-GAATTC'-3 sequence of DNA and develops a single-strand cut between the G & A nucleotides.

#SPJ4
A protein molecule is made from a long chain of these amino acids, each linked to its neighbor through a covalent peptide bond (Figure 3-1). Proteins are therefore also known as polypeptides. Each type of protein has a unique sequence of amino acids, exactly the same from one molecule to the next.
The answer is B. The reason is because in an RNA strand, A turns into U.

Answer:D. c, a, b, d
Explanation:humans can synthesis vitamin D as cholecalciferol in the skin when the skin is exposed to ultraviolet-B from the sun.this cholecalciferol is modified to calcidiol in the liver.this calcidiol is then modified to calcitrol in the kidney.parathyroid hormone activates the vit D
