Answer:
Labeled ddNTPs
Explanation:
The chain termination method or sanger method consist in 4 synthetis reaction at the same time. Each of them with a different labeled ddNTPs (ddATP, ddCTP, ddGTP and ddTTP) as part of it sythesis sustract. As the reaction goes on, if a ddNTP is added to the new DNA chain, it will stop the elongation becouse DNA polymerase activity depends on the presence of -OH extremes which are miss on ddNTPs.
Ans.
Diffusion, osmosis, and active transport are mechanism of cellular transport that involves movement of molecules through plasma membrane. Diffusion shows movement of small, hydrophobic particles without the help of protein molecules through cell membrane along the concentration gradient.
Osmosis involves movement of water molecules against concentration gradient (from an area of high solvent concentration to an area of low solvent concentration) through cell membrane.
Active transport shows movement of particles, against the concentration gradient, means from a region of higher to lower concentration of molecules through cell membrane. It involves transport through membrane proteins.
Thus, the part of cell, which is affected by the movement of molecules through osmosis, diffusion, and active transport is cell membrane or plasma membrane.
Explanation:
Molecular biology is a branch of biology that concerns the molecular basis of biological activity between biomolecules in the various systems of a cell, including the interactions between DNA, RNA, proteins and their biosynthesis, as well as the regulation of these interactions.
