Answer:
The correct answer is B. the two strands of DNA must separate.
Explanation:
DNA is a double-stranded structure. The two strands are joined together by the formation of hydrogen bonds between complementary nucleotides. So before the replication takes place these two strands must be separated.
The separation of DNA strand is accomplished by the action of a helicase enzyme which breaks the hydrogen bond between complementary nucleotides and separated the two DNA strands.
After separation, the DNA polymerase binds to separated DNA and replicating the DNA. So the right answer is B.
Answer:
The correct order would be
- Glucose
- ATP→ADP
- H₂O
- Pyruvate
- CO₂
Explanation:
Following reactions occur in Glycolysis and Kreb's Cycle
- Phosphorylation of Glucose- In the first step of glycolysis, Glucose is converted into Glucose-6-Phosphate using 1 ATP molecule by Hexokinase enzyme. One phosphate group from ATP is attached to glucose by the enzyme, thus forming ADP.
- Dehydration- In the ninth step of Glycolysis, each of two molecules of 2-Phosphoglycerate are converted to Phosphoenol Pyruvate, by Enolase enzyme, releasing two H₂O molecules.
- Formation of Pyruvate- In the last or tenth step of Glycolysis, each of two molecules of Phosphoenol Pyruvate are converted to Pyrutave using an ATP by the enzyme Pyruvate Kinase.
- Oxidation Of Pyruvate to Acetyl-CoA- Before the Kreb's Cycle starts, the Pyruvate molecule obtained from the Glycolysis undergoes oxidative decarboxylation producing Acetyl-CoA and release of CO₂ and NADH.
Answer:
An adequate sample of a population for studies of natural selection should
be large enough to:
represent the genetic variation in the population
Explanation:
Because it can cause some very bad cramps in the stomach
