The correct answer that would best complete the given statement above would be the first option: CONSERVATIONIST; SONOGRAPHER. A preference for working outdoors may be helpful if Lakeesha wants to become a conservationist, but not if she wants to become a sonographer. Conservationist is someone who is active in the protection and preservation of wildlife and the environment. A sonographer is someone who does a medical diagnostic procedure using ultrasound. Hope this answer helps.
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.
If a chromatographic column is not placed in a vertical position, the flow and the separation rate of the materials which are been separated may be negatively affected, that is, it may be slowed down, this is because the column is not inclined in the same direction as the flow of the separating substances. Also, collecting the products of the separation will be a bit difficult. If the column is placed in a vertical position, then a test tube can be placed at the end of the column for collecting the separated product
