Answer: without photosynthesis, there would not be any glucose or oxygen and those are what start off the respiration reaction. without respiration plants would use up all CO2 and starve to death. photosynthesis requires the products from respiration and vise-versa.
The correct answer for 1st part (
A) Smaller Interfering RNA (siRNA) and 2nd part is mRNA
During the whole procedure of RNA interference the long dsRNA is cut down into smaller fragments (nucleotides) by an enzyme called Dicer. These smaller fragments are called as Smaller Interfering RNA (siRNA) to bind to proteins. This Smaller Interfering RNA forms complex with RISC and helps in degradation of mRNA.
