Bio homework is the pits!
i hope i dont get Bio homework tomorrow! i HATE it:headache:
 
:wave:

I still haven't done the homework :p It's only 1 question I don't understand...

BIOLOGY HOMEWORK! A presentation -_- Maybe I can just use what I wrote about mononucleotides in my last homework, if I rewrite it, kinda...

mono...wah?
 

Mononucleotides are what DNA and RNA is made up of.
 
Yup, A Level stuff. Here's the full description (from my homework)

1. Mononucleotides are made up of 3 parts. A 5-Carbon (or Pentose sugar), a nitrogen-containing base and phosphoric acid. The pentose sugar in RNA is ribose, and in DNA, deoxyribose. Deoxyribose has one less oxygen atom then ribose. There are two types of nitrogen-containing bases in mononucleotides. There is the purine base, which have two nitrogen-containing rings, and there is the pyrimidine base, which only has one. The rings have the chemical property of being bases because of the nitrogen atoms they contain. DNA contains combinations of four different bases with equal numbers of pyrimidines and purines. The purines are adenine (A) and guanine (G). The pyrimidines are cytosine (C) and thymine (T). In RNA, the thymine is replaced with uracil (U). A phosphate group (PO43−) is the third component of a nucleotide. Inorganic phosphate ions are present in the cytoplasm of every cell. This phosphate group makes the mononucleotides. The sugar, base and phosphate group are joined together by condesation reactions to form the nucleotide.
