What is the significance of a recombinant plasmid?
drek231 [11]

Answer:

recombinant DNA

A strand of DNA formed by splicing DNA from 2 different organisms is called recombinant DNA

Explanation:

Using the techniques of recombinant DNA technology, certain enzymes known as restriction enzymes capable of cleaving double stranded DNA in the plasmid of bacteria genomes (other organisms like eukaryotes can also be used) are used to obtain specific sequences of DNA bearing desirable traits in the both organisms.

Once the two DNA fragments have been obtained, another enzyme known as DNA ligase is used to seal the point of splicing, thereby constructing a single DNA from the two organisms.

This single DNA is known as Recombinant DNA

Which macromolecule forms a double layer as the primary structure of cell membranes?
OlgaM077 [116]
Answer;
Phospholipid.

Phospholipid forms a double layer as the primary structure of cell membranes.

Explanation; 
Cell membranes contains of lipids (phospholipids and cholesterol), proteins and carbohydrates groups that are attached to some of the lipids and proteins. 
Phospholipids are composed of a polar head and non-polar (hydrophobic) tail. They line up such that the heads and the tail groups are side by side to form a single layer due to the interactions between the head groups and the tail groups. Two of these layers line up with the hydrophobic tail groups facing each other to prevent the hydrophobic groups away from the polar head groups of other phospholipids and from the water in the surrounding environment.
