What are restriction enzymes and how are they used to cut DNA?
Colt1911 [192]

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 bicoid mRNA is injected at the anterior end of an egg from a bicoid mutant mother, what would the phenotype of the resulting
JulijaS [17]

If the larva had one head at the posterior pole, it would be normal. The larva would have two heads, one at the front of its body and the other in the center.

What is bicoid mRNA?

When translated, bicoid protein forms a morphogen gradient that shapes the embryo's head and thorax if bicoid mRNA localizes to the anterior of the Drosophila egg.

How does the egg's bicoid RNA influence development?

According to recent research, Bicoid specifies the anterior of the Drosophila embryo in two different ways. It initially suppresses posterior development. It accomplishes this by attaching to and preventing caudal RNA, which is distributed throughout the egg and early embryo, from being translated.
