Answer:
restriction enzymes are enzymatic proteins which cleave DNA at specific sites. these proteins are contained inside the bacteria to cleave the foreign DNA particles from Bacteriophages. these enzymes can be isolated from the bacteria and can be used in vitro for DNA manipulation.
Explanation:
restriction enzymes cut DNA creating smaller segments.
Also name restriction endonucleases
examples:
HIND3, BAMH1, ECOR1, etc
The correct answer to this question is D. models can be used to describe
all of the environments listed here. Creating models is a great way to
gain a more practical understanding of how the complicated scientific
processes in these environments work, and as many people are
kinaesthetic learners it can aid them in learning.
The chickenpox virus is a highly contagious disease that can cause itchiness and produces a blister-like rash. It is caused by the varicella-zoster virus (VZV).
1. Varicella-zoster virus has the ability to switch from a latent lysogenic cycle to an active lytic cycle that reactivates after dormancy.
2. Varicella-zoster virus infects human cells. Basically, it infects and replicates the cutaneous fibroblast and epidermal cells and the several types of immune cells.
3. The person typically contracts this virus through inhalation. It enters the host's respiratory tract where it replicates in the nasopharynx as well as the regional lymph nodes.
4. This virus is characterized by red itchy blisters that can spread over the entire body.
