Since guanine - cytosine and adenine - thymine are are always paired in the DNA, the amount of cytosine is approximately the same as guanine and the amount of thymine is approximately the same as adenine
DNA is a double helix composed of nitrogenous bases, which form hydrogen bonds with each other. It also contains a deoxyribose sugar and phosphate backbone.
Answer:
Facilitate diffusion by using a transporter
Explanation:
Facilitate diffusion is a type of transport in which a transporter protein is used to transport the molecule across the cell membrane along its concentration gradient. As the movement is along the concentration gradient and does not require energy so it is a type of diffusion.
Glucose travels in the cell by facilitating diffusion because it requires transporter to move across the cell along the concentration gradient. In facilitating diffusion the rate of transport in high than simple diffusion.
