Sticky ends are produced by cutting the DNA in a staggered manner within the recognition site producing single-stranded DNA ends. These ends have identical nucleotide sequence and are sticky because they can hydrogen-bond to complementary tails of other DNA fragments cut by the same restriction enzyme
Answer:
The complete breakdown of glucose in the presence of oxygen occurs in two stages: glycolysis and citric acid cycle. The first of these stages occur in the cytoplasm of the cell, and the second stage occurs in organelles called Mitochondria.
Explanation:
The breakdown of glucose occurs in two stages. The first stage occurs inside the cytoplasm, it is called glycolysis. when a molecule of glucose undergoes glycolysis, the following are produced:
2 ATP (Adenosine triphosphate) molecules;
2 water molecules;
2 pyruvate molecules and;
2 NADH (Nicotinamide Adenine dinucleotide) molecules
The second stage occurs in an organelle called Mitochondria, it is called citric acid cycle or tricarboxylic acid or Kreb's cycle. In this stage, the two pyruvate molecules from the glycolytic cycle are reduced to carbon(iv)oxide. The following are produced:
2 ATP molecules;
6 NADH molecules;
2 FADH2 (flavine adenine dinucleotide) and;
4 molecules of carbon(iv) oxide.
The NADH and FADH2 molecules are used in the electron transport chain generates as much as 28 ATP molecules.
Unlike arteries, veins contain valves that ensure blood flows in only one direction. (Arteries don't require valves because pressure from the heart is so strong that blood is only able to flow in one direction.) Valves also help blood travel back to the heart against the force of gravity.
When a doctor refuses to care for a certain patient. This can be for numerous reasons, maybe they are not fit to undergo a surgery of some sort, or are being problematic. Either or the doctor nor the patient benefit form this. Doctor misses out on someone to help (i assume that’s the attitude of one working for the greater good) and the patient misses the opportunity to possibly get the help they need.
