Answer:
C) are sequence-specific DNA endonucleases
B) degrade foreign DNA that enters a bacterium.
Explanation:
Restriction enzymes are the proteins that cut the DNA at a specific sequence.
<u>Restriction enzymes are also known as restriction endonuclease produced by bacteria that recognizes a specific sequence on DNA and split it by catalyzing the hydrolysis or addition of water molecule. </u>So, Restriction enzymes are sequence-specific DNA endonucleases.
The biological role of restriction enzymes is to restrict the entry of foreign DNA into the bacterium. <u>Restriction enzymes have the ability to restrict the number of bacteriophage strains that affect bacteria.</u>
Hence, the correct options are "C and B"
Under extreme temperatures Enzymes become inactivated or denatured. due to this reason there will be no change in Photosynthesis despite a change in Light intensity.
Answer:
b) Travel quickly, allowing rapid transmission of signals:
Explanation
nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body very rapidly.
Answer:
Epithelium
Explanation:
Epithelium are tissue massage found mostly in the skin and serve as protective covering for the internal and external parts of the body.
A major characteristic of the epithelium is that its layers do not contain any blood vessels such as the artery or vein. The surface of the cells is also usually open to the internal cavity of the organ.
