Based on structure, in what way do dna molecules differ from rna molecules?

Unlike DNA, RNA is almost always a single-stranded molecule and has a much shorter chain of nucleotides. RNA contains ribose, rather than the deoxyribose found in DNA (there is a hydroxyl group attached to the pentose ring in the 2' position whereas RNA has two hydroxyl groups). These hydroxyl groups make RNA less stable than DNA because it is more prone to hydrolysis. Several types of RNA (tRNA, rRNA) contain a great deal of secondary structure, which help promote stability.

Explanation:

What is a RNA molecule?

Well, RNA consist of aminoacids. An aminoacid is built up of three bases, which is a micture of a nucleoside (organic molecule), phosphatgroup and the base (A,T,G,C). This package is also called nucleic acid.

So RNA is built up the same way as DNA, but it's just a helix and not a duople-helix (DNA) and has got the base U instead of the base T. You can see that RNA is a molecule because its built up of molecules.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
