Answer:
Connect the centromere to microtubules. (Option A)
Explanation:
The kinetochore is known as the complex of protein which is disc shape in structure. The structure of kinetochore is divided into three parts: inner region, outer region, and fibrous corona. Each part of the kinetochore works in its own way in the separation of the sister chromatids.
During the process of cell division (mitosis, and meiosis) kinetochore collects on the centromere and allows the chromosome to link with microtubules.
The membrane structures that function in active transport are proteins and lipids. Proteins function in active transport as pumps.
Answer:
The term gene expression means the process by which the information encoded in our DNA is used to synthesize a functional product, such as a protein molecule or other cell structures.
Explanation:
<span>Rough ER is called rough because it has ribosomes attached to its surface. The double membranes of smooth and rough ER form sacs called cisternae. Protein molecules are synthesized and collected in the cisternal space/lumen. When enough proteins have been synthesized, they collect and are pinched off in vesicles.</span>
