Explanation:
Restriction enzymes are enzymes (endonucleases) that cut short DNA strands at specific sites. Hence, each restriction enzyme has it's own specific site (between two bases) it cuts at. There are two types of end that can be produced by this cut; the blunt end and the sticky end.
A restriction enzyme recognizes (palindromic sequence) and cut in it's own specific end.
For example, if a restriction enzyme cuts between a guanine (G) and an adenine (A), and it cuts a palindromic double stranded DNA in the manner below, it produces a sticky end.
G║AATTC
CTTAA║G
And if a restriction enzyme cuts between guanine (G) and cytosine (C) in the manner below, it produces a blunt end.
GGG║CCC
CCC║GGG
Hence, from the question, restriction enzymes (although chosen by the scientist based on desired sequence to be cut) recognize the sticky or blunt ends itself.
Answer:
The perceived economic impact of CO2 generated per year by lighting sstem is $8164.67.
Explanation:
The CO2 requirement for the plant is:
Amount of CO2 per year = (2.4 lb / KWh)(300,000 KWh)
Amount of CO2 per year = (720000 lb)(1 ton/ 2204.62 lb)
Amount of CO2 per year = 326.59 ton
The perceived economic impact of CO2 generated per year will then be:
Economic Impact = ($25 / ton)(326.59 ton)
<u>Economic Impact = $8164.67</u>
It is study of the relationships between heat, temprature, work and energy
