Answer:
Main Difference – Mutation vs Variation
Mutation and variation are two simultaneous events involved in the process of evolution. The main difference between mutation and variation is that mutation is an alteration in the nucleotide sequence of a gene whereas variation is any difference between individuals of a particular species. Mutations may arise due to environmental factors such as chemicals and UV. Germline mutations are inherited by the offspring. Somatic mutations occur in the ordinary body cells. Variation can occur due to mutations, genetic recombination, gene flow, genetic drift, random mating, random fertilization, and environmental factors. Variation may also cause evolution through natural selection.
Answer: consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder).
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.
