Length of PolyA tail is different in two cells
Explanation:
- Different lengths of Poly A tails are present for different mRNAs so when we compare two peptides translated in two different cells we have different lengths of PolyA tail
- PolyA tail is basically a long chain of nucleotides(adenine nucleotides) which are added to messenger RNA(mRNA) during processing of RNA
- It increases the stability of the molecule
- It protects the mRNA molecule from undergoing degradation in the cytoplasm
- It is involved in binding proteins which further initiates translation;introns are removed from pre mRNA before the final mRNA is exported into cytoplasm
Answer: Coastal areas have moderate temperature because the land absorbs and radiates heat much faster than sea. So, during the day cool air from sea rush towards the land and during night cool air from the land rush towards sea

Answer:
Density and density-independent factors for populations. Density-independent variables including geography and atmosphere affect city size independently of population density. The effects of density-dependent factors are, however, steadily increasing as the population grows.
