NUCLEIC

1

• NUCLEIC
• ACIDS

2

• 2 Types DNA and RNA
• Makeup your genes
• blueprints for proteins sequence of a.a.s
• control the life and functioning of a cell
• Material of heredity
• DNA Deoxyribonucleic Acid
• RNA Ribonucleic Acid

3

• monomers nucleotides

• Each composed of a sugar, a phosphate, and a
  nitrogenous base

Nitrogenous base (A)
Phosphategroup
Deoxyribose sugar
5 carbon sugar
4
4 different nitrogenous bases

• ADENINE
• THYMINE

• GUANINE
• CYTOSINE

Order of bases in nucleotides spells out the
instructions for proteins
5

• sugar and phosphate form polymer backbone of the
  nucleic acid molecule

HOW MANY NUCLEOTIDES IN THIS DIAGRAM?
Sugar-phosphate backbone
6

• DNA two polynucleotides twisted around each
  other in a double helix

• The sequence of the four kinds of nitrogenous
  bases in DNA carries genetic information

Base pair
Complimentary Base Pairing- A bonds only with
T G bonds only with C
Nitrogenousbase (A)
7

• RNA - a single-stranded nucleic acid 1 side only
• RNA contains ribose sugar
• RNA Adenine, Guanine, Cytosine and Uracil
• A bonds to U and G bonds to C
• RNA is the instructions for one specific protein
• Tells the ribosomes what to make!

8

• DNA
• Inherited characteristics
• Controls and directs all cell activity
• Monomers are nucleotides
• DNA 2 sided chains/polymers of nucleotides
• Nucleotides contain deoxyribose sugar
• DNA Bases are
• adenine, guanine, cytosine and thymine

• RNA
• Not inherited synthesized in cell
• Messenger within the cell for DNA
• Monomers are nucleotides
• RNA 1 sided chain/polymer of nucleotides
• Nucleotides contain ribose sugar
• RNA Bases are
• adenine, guanine, cytosine and uracil
