Transcript and Presenter's Notes

Title: 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
