The breakdown of telomerase when DNA is replicated from a parent (old) cell to a daughter (new) cell. Telomerase is a protein that serves as a protector to the information in the DNA molecule, and is also responsible for the maintenance of cell health.
The upside is, people don't start to age until this protein begins to fail at protecting its DNA molecule, and faulty DNA is replicated. This is why babies do not have poor skin or faulty complexions, and why they do not suffer such superficial things as WRINKLES. (This is not including genetic abnormalities, which can't be compensated for unless damaged DNA actually fixes the problem....)
The downside is that cancer cells use this poor, defenseless protein as a power source, and why cancer cells are, literally, immortal.
if you want the study island answer it is (the unique sequence of nucleotides)
Their arrangement of the DNA bases makes them different.
the chromosomes that are in the DNA makes it different from the other DNA.
protein
histone proteins envelope DNA molecules inside the cell.
mRNA makes a complimentary copy of the DNA molecule according to the base-pairing rule.
DNA is a molecule so no.
the chromosomes that are in the DNA makes it different from the other DNA.
they break apart and they find other DNA strands and form more DNA strands.
a DNA molecule has two paired strands. ~
protein
Heck No!
The sides (uprights) of the DNA molecule are composed of alternating deoxyribose sugar molecules and phosphate molecules.
histone proteins envelope DNA molecules inside the cell.
Deoxyribose sugars and phosphates make up the backbone of DNA.
mRNA makes a complimentary copy of the DNA molecule according to the base-pairing rule.
DNA (Dioxyribonucleic Acid)
DNA is a molecule so no.
A characteristic of a DNA molecule that is not characteristic of a protein molecule is that the DNA molecule can replicate itself.
