Explanation:
Each eukaryotic chromosome usually has repeated telomere sequences ranging from 2 to as many as 2000.
There is normally just one specialized DNA sequence called the centromere per eukaryotic chromosomal DNA molecule.
The origin of replication is the site where DNA duplication starts in S phase.
The centromere attaches the chromosome to the mitotic spindle via the kinetochore structure.
Teleomere contains repeateted sequences at the ends of the chromosomes.

Answer:
Radioactive labeling is a procedure used to monitor the path followed by a chemical element within a biological system to demonstrate the source.
Hypothesis:
The free oxygen produced during photosynthesis comes from water.
Procedure.
Single-celled algae were placed in four petri dishes containing carbon dioxide, glucose dissolved in Water.
In each box the oxygen was radioactively marked.
1 petri dish with CO2 marked. Experimental groups
2 petri dish with H2O marked. Experimental groups
3 petri dish with Glucose marked. Experimental groups (control)
4 petri dish with CO2 + H2O + Glucose, all marked. (control).
Adenosince Triphosphate is broken down into one molecule of inorganic phosphate and a molecule of adenosine diphosphate, the energy released from this bond is captured and use to drive most cellular processes. some form of carbohydrate or triglyceride is used to generate the ATP in the first place depending upon a particular species and needs at the time
