Answer: 1- a(cofactor)
2.-c(apoenzyme)
3-b(coenzyme)
Explanation:
Cofactor are non -protein molecules that catalyzes reaction,they increase the rate of chemical reaction. They can be organic or inorganic.
Coenzyme can be derived from vitamins,organic molecules, they facilitate chemical reaction and can be bounded strongly to protein while others are bounded loosely to protein.
Apoenzyme are inactive enzymes that cannot catalyze reaction they lacks cofactor.
Answer:
Persistent infection
Explanation:
Viruses have the ability to remain in the host cell in a dormant state or latent state for many years. This is a part of reproduction cycle of a virus called the lysogenic cycle. This causes persistent infection in the host because the virus remains in the host cell and cause infection.
This persistent infection can cause cancer in the host because the viral genome incorporates in the host cell genome and take controls on its gene machinery. For example, HPV can incorporate itself in the host genome and can alter it which can cause cancer. So the correct answer is persistent infection.
Answer:
Explanation:
Insertion/deletion of 3 base which is a condon will be less fathal because only one amino acid will be missing from the protein of which the gene codes for.
If one codon is deleted it will still be the same but might cause a disease for example in cystic fibrosis one amino acid, 508th Phenly alanine is missing in the CFTR protein. They severity of diseases caused by Insertion or deletion is increased as the number of condon are more.
However, if only one or two is deleted/inserted then all the codons will shift causing them to be in different groups which may form a totally different amino acids as seen in frameshift mutation. This is more dangerous.
Answer: B
Explanation: Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids.
The correct answer is C) only some survive because variation exists
