RNA

RNA is very similar to DNA...it is also a polymer that is made up of nucleotides as the monomers.

The key concepts to remember with DNA are:
* Ribose is the sugar of the backbone
* Uracil is the base that replaces Thymine (only U, never a T)
* single stranded

Structure of DNA

DNA is found within the nucleus of all cells. DNA are our genes or our 'blue-print'.

DNA is a large polymer...made up of NUCELOTIDES. (take this time to review your organic macromolecules!!) Here is a sketch of a nucleotide...


The shape of DNA is a DOUBLE HELIX...which is simply just 2 strands twisted together...think of a spiraled staircase, twisted ladder or a zipper


The backbone of DNA is made up alternating of PHOSPHATE and DEOXYRIBOSE (a sugar).

The bases of DNA are: Adenine (A), Cytosine (C), Thymine (T) and Guanine (G). These are the only bases found in DNA. The bases will always, always, always pair up A-T and C-G...no ifs, ands or buts!!

History of DNA

DNA stands for Deoxyribonucleic Acid. DNA is a fairly new discovery in the world of science. It was first seen in the early 1920's, but the actual structure wasn't found until February 1953. Upon it's discovery DNA became known as "the secret of life".

Mitosis vs. Meiosis

MITOSIS is the division of somatic (body) cells...the stages are INTERPHASE, PROPHASE, METAPHASE, ANAPHASE & TELOPHASE followed by CYTOKINESIS

MEIOSIS is the division of sex cells...same stages x2 as mitosis
