Answer:
It ensures that sexually reproduced offspring have the correct amount of chromosomes when born, this ensures that disorders such as down syndrome don't occur. It also makes genetic variation possible, by way of genetic recombination, this is so that siblings don't look exactly the same, disregarding twins.
Explanation:
<span> answer: poor regulation of the brain's locus </span><span>ceruleus may lead to panic attacks</span>.
Locus ceruleus is a nucleus in the pons involved with physiological responses to stress and panic. When there is stress he responds by increasing norepinephrine (NE) secretion, which is a critical
regulator of numerous activities from stress response. Panic attacks result from alterations to NE.
siRNA prevent gene expression by binding to the product of transcription because <u>they bind to mRNA</u>
Explanation:
siRNA are short-sequence RNA strands, about 20 bp long, that bind to complementary regions on transcribed mRNA. This causes the formation of regions of dsRNA on the mRNA. This subsequently result in recruitment of enzymes such as Diver enzyme to cleave the mRNA and hence rendering it ineffective for translation into proteins. This is how siRNA negatively regulate genes, a process that has also been identified in research as a window to remedy genetic diseases.
