Prof Katty :D

Today was our first class with Prof Datin Paduka Dr Khatijah. She will teach my class for four lectures- Microbial genetics. Our first lecture was on structure and function of genetic materials.

Genetics: is the science of heredity

Genome: genetic information in a cell

Chromosomes: structures containing DNA that carry genetic information

Genes: segments of DNA that code for functional products.

DNA – deoxyribonucleic acid. It is for storage of genetic information, self-duplication and inheritance and expression of genetic message.

RNA – ribonucleic acid

Nucleic acids- Adenine(A), Guanine(G), Cytosine(C), Thymine(T)[Uracil(U) in RNA]. The pair is AT/U(2 hydrogen bonds) and GC(3 hydrogen bonds).

Genotype is genetic composition of an organism, information that codes for all the characteristics.

Phenotype is actual expressed properties of an organism, which are observable characteristics and manifestation of genotype.

The process of producing protein from nucleic acid- DNA replication, transcription, translations. DNA replication always proceed from 5’ phosphate to 3’ hydroxyl.  It is proofreading by DNA polymerase. Transcription is synthesis of a complementary strand of RNA from a DNA template. Lastly, translation is a process in which information in the mRNA is used to dictate the amino acid sequence of a protein.

These are actually some of what we learned earlier today. The class was interesting of course. Because learning from someone who has so many experience and knowledge, we could listen to her story and became inspired. She shared some of her story, and I am looking forward to our next class!
