DNA and Genetics

Annotations:

  • Chapter 1 - Science Dimensions  10
1 Deoxyribonucleic Acid (DNA)
1.1 Molecule Structure

Annotations:

  • Refer to Figures 1.1.1 to 1.1.5
1.1.1 The same structure in all living things
1.1.2 Twisted ladder shape

Annotations:

  • Figure 1.1.2
1.1.3 Made up of nucleotides
1.1.3.1 Nucleotide structure

Annotations:

  • Nucleotides are made up of a deoxyribose sugar component, phosphate component and a base component (adenine, thymine, guanine or cytosine).
  • Figure 1.1.1
1.1.4 Rung details

Annotations:

  • The rungs (really called complementary base pairs) are pairs of nitrogen rich bases. There are four types of bases: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).
  • Of the four bases, only two pairs can be made - AT is one, and CG is the other.
1.1.4.1 Only sugar components can connect to rungs
1.1.4.2 Genetic code is the order of the bases
