Consider the following statement and mark the wrong -a)Most cancers ar...
Explanation:
To mark the wrong statement, we need to evaluate each option and determine if it is true or false. Let's analyze each statement:
a) Most cancers are treated by combinations of surgery, radiotherapy, and chemotherapy:
This statement is true. In many cases, the treatment of cancer involves a combination of these three approaches. Surgery is used to remove the tumor, while radiotherapy and chemotherapy are employed to kill any remaining cancer cells and prevent their spread.
b) Cocaine interferes with the transport of neurotransmitter dopamine:
This statement is true. Cocaine acts as a dopamine reuptake inhibitor, meaning it prevents the reabsorption of dopamine by the nerve cells that release it. This leads to an accumulation of dopamine in the synaptic cleft, resulting in increased stimulation of the postsynaptic receptors and producing the characteristic effects of cocaine.
c) Reverse transcriptase enzyme is active in the cytoplasm of virus-infected cells:
This statement is true. Reverse transcriptase is an enzyme that catalyzes the synthesis of DNA from an RNA template. It is commonly found in retroviruses, such as HIV, and is active in the cytoplasm of virus-infected cells. This enzyme plays a crucial role in the replication of retroviruses by converting their RNA genome into DNA.
d) There is no time lag between infection and the appearance of AIDS symptoms:
This statement is false. There is a significant time lag between HIV infection and the development of AIDS symptoms. HIV (Human Immunodeficiency Virus) is the virus that causes AIDS (Acquired Immunodeficiency Syndrome). After HIV infection, it can take several years for the virus to replicate and damage the immune system enough to lead to the development of AIDS symptoms. This period is known as the asymptomatic stage or latency period. During this time, individuals may not experience any symptoms or may only have mild, non-specific symptoms. It is important to note that the duration of this latency period can vary among individuals.
Therefore, the correct answer is option 'D' as there is a time lag between HIV infection and the appearance of AIDS symptoms.
