Answer:
D. MicroRNA-1/206 targets c-Met mRNA for destruction via RISC.
Explanation:
microRNA's are non-coding RNA's, that is, they are not translated to proteins. MicroRNA-1/206 leads to gene silencing by 'tagging' the c-Met mRNA for cleavage by RISC proteins.
RISC: RNA-induced silencing complex is a ribonucleoprotein complex that leads to the incorporation of a single strand of micro RNA (or siRNA) that will bind to the targeted mRNA. The microRNA or siRNA strand will tag the targeted RNA for cleavage by proteins from the ribonucleoprotein. No translation will occur.
Answer:
D. Enzymes only break down large molecules.
Explanation:
Enzymes are the substances which helps in the broken down of large food molecules into small molecules. It is because our body is not able to absorb large food molecules, these large molecules are broken down into small molecules with the help of enzymes. Carbohydrate is broken down into glucose by amylase and protein is broken down into amino acids by protease. Enzyme is non-living in nature and used as a catalyst in order to speed up the chemical reaction.
When the rates of the forward and reverse reactions are equal. The system is dynamic because individual molecules react continuously. It is at equilibrium because no net change occurs.
Mutation is needed for evolution to occur to ensure that strong species will dwell within the environment. Though this has little effect on allele frequencies, mutations still ensure the biodiversity of species. The theory of natural selection in a way proves this.
