Required properties of a genetic material:
It must contain information that control the synthesis of protein and function.
It must be able to self-replicate.
It must be located in the chromosomes, which had been found to carry traits from one generation to the next.
1) 2)
Types of genetic materials:
DNA: is the genetic material in most organisms, such as humans, animals, plants, viruses, and bacteria.
RNA: in some viruses, RNA serves as the genetic material.
1) 2) Types of nucleic acids DNA (deoxyribonuclic acid) RNA (ribonuclic acid)
The structure of nucleoside and nucleotide Nucleoside= nitrogen base + sugar Nucleotide= nitrogen base + sugar + phosphte
The structure of the four nucleotides
A polymer of nucleotides
The Watson-Crick model
Hydrogen bonds
Polarity of the DNA strand
