Answer:
<u><em>They take nutrients needed by healthy cells, and as they grow they interfere with the function of normal cells and organs.</em></u>
Explanation:
Many mutations can lead to the formation of cancer. Cancer can be described as an abnormal type of cell division of the cells of the body. As cancer cells are the cells of the body dividing abnormally, the immune cells fail to fight them. These cells keep on dividing and also disturb the functioning of the neighbouring cells and tissues. They even take up most of the nutrients required by normal body cells hence, being very toxic for the normal cells.
The proteins exhibit four levels of organization:
1. Primary structure: It refers to a sequence of amino acids join together by the peptide bonds to produce a polypeptide chain.
2. Secondary structure: It is a localized twisting of the polypeptide chain by producing a hydrogen bond. Two types are formed, that is, the alpha helix and beta pleated sheet.
3. Tertiary structure: It refers to the three-dimensional composition of a polypeptide chain. The folding is not regular as it is in secondary composition. It produces ionic bonds, hydrophobic interactions, disulfide bond, and hydrogen bond amongst the polypeptide chains.
4. Quaternary structure: It comprises an amalgamation of two or more polypeptide chains that functions as a single functional unit. The bonds are identical as in tertiary composition.
Thus, the levels of secondary, tertiary, and quaternary protein structure would get affected if all the hydrogen bonding associations were inhibited.
Need a picture of the diagram pls
Answer:
The smallest size tube that will hold the entire reaction is 0.5ml
Explanation:
25ul (DNA sample) + 25ul (enzyme) + 50ul (buffer) + 400ul (water) = 500ul total
since 1000ul=1ml, then 500ul = 0.5ml
Answer:
The device that mostlikely would not be used P20
Explanation:
P20 is a pipette used to measure and sample volumes of 20ul maximum.
Answer:
The reaction mix will have 400 units of the enzyme.
The working dilution will be 0.8 Units/ul.
Explanation:
The mix has 20ul of the enzyme which is 20Units/ul. Then we have 20ulx20Units/ul= 400 Units of enzyme in the mix.
Since the final volume is 500ul, the final concentration 400Units/500ul=0.8 Units/ul.
