Molecular biology (Zoo-342)
Aims of the Molecular Biology course To study the properties of genetic material. To understand the structure of DNA and its organization in chromatin. To understand the structure of RNA and its types. To understand the of DNA replication. To understand the key features of gene. To study the gene expression: Transcription in prokaryotic cells. To study the gene expression: Transcription in eukaryotic cells. To study the gene expression: Translation in prokaryotic cells. To study the gene expression: Translation in eukaryotic cells.

Required properties of a genetic material: It must contain information that control the synthesis of protein and function. 2) It must be able to self-replicate. 3) It must be located in the chromosomes, which had been found to carry traits from one generation to the next. 1) Types of genetic materials: DNA: is the genetic material in most organisms, such as humans, animals, plants, viruses, and bacteria. 2) RNA: in some viruses, RNA serves as the genetic material. 1)
Types of nucleic acids 1) DNA (deoxyribonuclic acid) 2) RNA (ribonuclic acid)
