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.

Answer:
Small intestine, liver, bile and lipase.
Explanation:
Digestion of fat occurs in the small intestine. Its digestion occurs with the help of bile, that is made in the liver. Bile breaks the fat into small drops that are easier for the lipase enzymes to change it. Lipase enzymes is a type of enzymes that works only on lipids and lipids are broken down into fatty acids and glycerol. These substances are absorbed by our body and used it for producing ATP for the body.
Looking at chemical reaction given in the question above, it can be seen that the chemical reaction needs heat to proceed. If the temperature of this reaction is increased, the rate of chemical reaction will also increase. That is, if the temperature of the reaction is increase, the product of the reaction that is formed per time will also increases.<span />
