Answer:
Most genetic disease result from mutation that causes a gene to produce non functioning Protein.
Explanation:
Mutation deals with alteration of nucleotide sequence of the gene that encodes a functional protein product.
As a result of mutation the open reading frame of the mRNA sequence transcribed from that gene is being changed. Due to which the mutated gene can no longer form functional protein. This ultimately leads to production of non functional or truncated protein or disease causing protein.
For examle the Sickle cell anemia is caused due to the mutation in the beta chain of hemoglobin resulting in the accumulation of insoluble aggregates of HbS .
Answer:
none of the above
Explanation:
The options cited in the question do not influence water conservation. Attitudes that can promote water conservation are: tightly closing the taps, adjusting the discharge valves and eliminating water leaks, do not leave the shower turned on, brush your teeth with the tap closed, use the bucket and no hoses to wash the water. car and sidewalks, use the water that comes out of the washing machine to wash sidewalks, do not throw garbage in the river, do not throw garbage on the beach and publicize and participate in educational campaigns for water conservation.
Answer:
True
Explanation:
In Retrovirus such as HIV, when the virus enters the host's cell it releases enzyme reverse Transcriptase which generates a complementary DNA(cDNA) by the process called Reverse transcription.
By this process the positive single stranded RNA genome is liberated into a cDNA molecule.
Since the process of reverse transcription is prone to errors, it can cause mutation that lead to drug resistance or enable the virus evade the body's immune system.
