The correct answer is B.
The cell membrane is a two-layer lipid membrane that surrounds and protects the cell. It allows only certain molecules to enter and leave the cell, that's why we call it semi-permeable. The membrane is permeable only for small,uncharged molecules which enter and leave in the process of osmosis. All other types of molecules require a special transport protein or a channel in order to be transported trough the cell membrane.
A benefit of genetic engineering is the production of valuable proteins that have helped in managing of illness in human beings. Bacteria were genetically engineered to produce proteins of medical importance. One example of such a protein is human insulin which is given the name humulin and is made using E. coli bacteria.Earlier, insulin from pig cells was used to treat patients with diabetes but many of them could not tolerate it because it has a slightly different arrangement of amino acids from that of humans and so the human body rejects it. Humulin is tolerated by the human body and so many patients are now using it to lead normal lives.
Answer:
By forming chromatin and in the condensed form of chromosomes
Explanation:
The human genome contains around 3 billion base pairs which are located in the nucleus of all cells. In order to accomodate such large genomic information, DNA is maximally supercoiled during mitosis and meiosis processes to form condensed structures called chromosomes. Humans have 23 pairs of chromosomes per somatic cell. The supercoiling process is assisted by a family of proteins called histones, which interact with DNA and regulate its conformation. The complex between DNA and histones within the nucleus is called chromatin. When chromatin is supercoiled it form chromosomes (in eukaryotic cells).
