Because different restriction sites are used by different restriction enzymes to cleave DNA.
<h3>What is restriction sites?</h3>
- A restriction site is a segment of DNA with a base pair count between 6 and 8 that binds to a certain restriction enzyme. There are numerous restriction enzymes that have been identified from bacteria. By cleaving the viral DNA, they naturally render invasive viruses inactive.
- Restriction enzymes are beneficial in a variety of contexts. Each organism has a unique DNA sequence, so each one will have a unique arrangement of restriction sites.

Answer:
28% Thymine
Explanation:
DNA molecule is made up of four nucleotides namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). These nucleotides make up the DNA molecule unevenly, however, according to Chargaff in his rule, he stated that the amount of Adenine&Thymine, Guanine& Cytosine in a DNA must be equal, which must all equate to 100% i.e. (A = T) + (G = C) = 100%
Based on this Chargaff's rule, if a DNA sample is analyzed and found to contain 22% of cytosine. This means that the amount of Guanine in that DNA sample must also be 22%.
Therefore; 22% C + 22% G = 44%
100 - 44 = 56%. This means that Adenine and Thymine will share this 56% among each other i.e. 56/2 = 28% Adenine and 28% Thymine.
Explanation:
destroy the RNA polymerase altogether
B. use antibiotics to destroy the RNA polymerase before initiation
C. stop the RNA polymerase from moving along the DNA strand.
Ehlers-Danlos syndrome affects the connective tissue such as the skin and the joints, so the answer would be A. Hope this helps:)

Answer:
Nitrogen
Explanation:
Legume roots produce their own nitrogen, which is a major fertilizer nutrient needed by all plants for growth. Nitrogen is produced in nodules that form on the roots of legumes, which contain Rhizobium bacteria. The bacteria take nitrogen from the air and convert it into a form the plants can use.
