The DNA is found in the nucleus of the cell
1. D 2. A 3. C 4. B tell me if I’m right
Answer:
adsorption, penetration, biosynthesis, maturation, release
Explanation:
The virus after infecting the cell produces several progenies which after reaching a certain number cause the lysis of the cell and are then released out from it. This process of entering the host by the virus and then lysing the cells to be released is termed as a lytic cycle.
There are 5 stages involved in this lytic cycle:
1. Adsorption - when the virus finds its attachment site on the bacteria it gets attached to the viral receptor and then is adsorbed on the bacteria, this is the first step required to gain entry into the host.
2. Penetration - once the virus is attached to the host the next step is to penetrate it and enter inside the cell. For this, the virus secretes lysozyme and then inserts its genetic material inside the cell.
3. Biosynthesis - this stage involves the utilization of the enzymes and nucleotides of the host to make up the DNA of the phage.
4. Maturation - once the phage DNA is made the next stage is to assemble the phage DNA with the capsid and this is termed as maturation.
5. Release - this step involves the breakage of the plasma membrane of the host cell and the release fo the phage particles.
1.This is a point mutation where thymine(T) has been replaced with adenine(A) in the DNA.
2.In the messenger RNA the codon will be changed Adenine(A) is replaced with uracil(U)
3.The changed codon will cause a different amino acid to be placed. Glutamic acid is replaced with valine. This replacement will cause the protein to be deformed and have an altered function.
