Answer:
The chemical basis of Chargaff"s rule is the bonding properties of the DNA bases.
Explanation:
According to the Chargaff"s rule in a DNA molecule the total number of purine bases are equal with the total number of pyrimidine bases that means
Adenine +Guanine=Thymine +Cytosine
In simple words the rule is based on the 1:1 ratio of both purine and pyrimidine bases.
Answer:
Explanation:
ATP can be described as the unit for energy. Cellular processes that can involve ATP/energy are
1) Respiration: This involves the cells obtaining ATP by means of combining oxygen and glucose.
2) Metabolism: This is the building up (anabolism) and breakdown down (catabolism) process. Generally, anabolism requires ATP while catabolism releases ATP.
3) Active transport: This requires ATP to move substances or molecules across the cell membrane from a region of lower concentration to a region of higher concentration.
4) DNA replication: ATP is required to sustain replication of DNA at the replication fork during.
5) processes in the cell cycle: ATP is required for the S phase and the mitotic phase of the cell cycle.
6) Ion transport: Ion transport also requires the use of ATP to transport ions across the membrane of cells
4.75 billion years ago, a large star near what is now the Solar System went supernova, sending heavy element debris outward into the galaxy. Some of the debris, after traveling long distances through space, collided with a Hydrogen cloud.
I believe it is D as it is a better answer than D because of the fact that the statement does not explein the age of her grandmother "old" is just drawing a conclusion off nothing, and it does not say that she does not like her at all , thus it is an incorrect statement . So the answer is D.
