Explanation / Answer

14 ans-Vector origin

cloning site contain may unique restriction site,selectable markers are a type of reporter gene and they are mostly antibiotic resistance,it also contain atleast one replication of origin.

15 ans- expression vector

produce a protein through translation of mRNA,it contain regulatory sequence thatacts as a enhancer and promoter.

16 ans-b- they are lacking a 3' hydroxyl group

for prevention of the nucleotide chin elonation and forming a phosphodiester bond.

17 ans-Nucleic acid and protein

microarray is a multiplex lab-on-a-chip. which is used in data DNA, RNA and protein.
