Explanation:
Answer:
<em>Both the parents are carriers of sickle cell anaemia.</em> A carrier can be described as a person who carries a diseased causing allele but the allele is not functional in the body of the person due to the dominant allele suppressing its activity. Such kind of people might produce children actually having the disease.
In the above scenario, <em>there is a 25% chance that the children born will be normal. </em>
<em>There is a 50 percent chance that the children born will be carriers, like the parents.</em>
<em>There is a 25% chance that the child born from these parents might have sickle cell anaemia.</em>
Answer:Isocitrate is oxidized and decarboxylation occurs with a carbon dioxide molecule released.
Explanation:
The right answer is the promoter.
• The promoter is a nucleotide sequence that allows the transcription of the gene into mRNA. It is recognized by the RNA polymerase that initiates transcription. During the synthesis of the RNA, the promoter indicates which gene must be expressed and therefore which proteins the cell must produce. In an operon it is common to all genes.
• The operator is a segment of DNA and / or messenger RNA to which a chemical signal (a regulatory molecule) binds. It can be either a repressor signal or a transcription activating signal (DNA operator) or translation (RNA operator) of the genes of the operon. The RNA polymerase does not recognize this structure.
