DNA And RNA
Deoxyribose Nucleic Acid
DNA is made up of units called nucleotides. They are made up of three parts sugar, phosphate, and a nitrogen base.
Chargaff Rule: # of A=T + #of G=C
A=T G=C
30=30 40=40
Base pairing sequence: CTGCTA
GACGAT
AGATTCG
TCTAAGC
RNA= Ribonuclecic Acid
SIngled strand
4 bases
Adenine (a) A bounds U
Guanine (g) G bounds C
Cytosine (c)
Uracil (u)
RNA comes from DNA
If DNA is GCATCAGT
Then RNA CGUAGUCA
​
If DNA is AGTCCAATG
then RNA is UCAGGUAC
RNA creats protein
DNA is housed in nucleus 'RNA is housed in nucleus , cytoplasm, ribosomes.
Shape= Double Helix
​
A specific section of DNA that codes for a trait is called a gene
A chromosome a threadlike structure that contains genetic information that controls traits
