Answer:
ABC transporter protein
Explanation:
ABC transporter protein refers to the ATP binding cassette protein which utilizes the AT energy to transport the substrates from one side to another side. The ABC proteins are one of the oldest proteins known in the organisms.
The CFTR protein which acts as a chloride channel in the membrane which transports the chloride ions across the membrane utilizes the ATP energy in the transport.
Thus, ABC transporter protein is correct
first, third, fourth, second
RNA has Uracil instead of Thymine. All the other three bases also occurs in RNA, adenine, guanine and cytosine. Therefore a ATA DNA codon will be transcript to UAU by RNA. Both Thymine and Uracil have the same role in however have minor chemical differences.
Answer:
d. all of the above are true.
The hydrolysis of triglycerides on a spirit blue agar plate most closely resembles that of beta hemolysis on a blood agar plate.
The hydrolysis of triglycerides on a spirit blue agar plate is used for identifying bacteria based on what organic compounds they can break down, in this case lipids. Spirit blue agar is a medium that contains a supply of lipids. If bacteria have lipase, the enzyme capable of breaking down lipids spirit blue agar will be digested and it will appear as a halos around colonies of bacteria that make lipase.
The ability of bacterial colonies to induce hemolysis (the breakage of red blood cells) when grown on blood agar is used to identify microorganisms. Beta hemolysis is a complete lysis of red blood cells and in the blood agar, that area under the colonies that do the hemolysis appears lightened and transparent.
