Answer: The correct answer is skin,eyes, mouth, stomach.
Answer:
C
Explanation:
The DNA in all the cells of an organism are the same. The reason there are different types of cells in the organism even through their DNA is the same is because genes are deferentially expressed in the cell types. The genes that are expressed in the brain cells are different from those expressed in the liver. The rest of the genes that are not being expressed are silenced through folding by histones – so they are not exposed to DNA polymerase.
Answer:
D) The virus has entered the genome of the bacterial cell and is in the lysogenic stage.
Explanation:
Virus have two reproductive cycle lytic and lysogenic cycles. In the lytic cycle, the viral genome is expressed using the host molecular machinery and make capsid proteins. These capsid proteins surround the viral genome and make new phages which lyse the host cell and gets released.
After the release, they enter their genome in other host and that genome first incorporates in the host genome and replicates with the host genome. This cycle is called the lysogenic cycle and in this cycle lysis of cell does take place because no new phages are produced in it.
