Day by Day, Microbes are Interesting :*

NOVEMBER 18, 2014; TUESDAY; 10.00a.m.-12.00p.m.; ta BS 1.4

Hi and Assalamualaikum:) :)

I came to class late at 10.20a.m. Actually at 9.30 I'd ready to go to class but a felt sleepy because last night I sleep quite late then I fall a sleep at 9.30a.m. HUHU. Lucky Prof didn't ask me anything.HUH

Lecture 3

1. We have to be able to define mutation : any inheritable change in the base sequence of DNA. 
2. We have to be able to classify mutation by type :

• Base Substitutions (Point Mutation)

a) Silent

b)Missense

c) Nonsense

• Frameshift Mutation

a)Insertion or deletion

b) Shift in the reading frame

Watch this video to more understand about type of mutations

     3. We have to be able to define mutagens : Biological, chemcial, or physical agent, process or substance that cause permanent genetic change (mutation) in a cell due to genetic alterations or loss of genes or chromosomes.

NOVEMBER 21, 2014; FRIDAY; 8.00 a.m.-10.00a.m.

At morning, we have class at BioTech2 with Dr. Wan.. Waa,, miss her so much!

Continued for topic on Viruses and Other Acellular Infectious Agents

Scrible I

Scrible II

Acellular agents : Not a living cell until it take over their metabolism of host.

1. We have to be able to defines the terms of virology : is the study of viruses - submicroscopic, parasitic particles of genetic material contained in a protein coat and virus-like agents. Bacteriophages : A virulent virus that kill phatogenic bacteria that harmful to human. Phages : Short for bacteriophage, a virus that lives within a bacteria. A virus for which the natural host is a bacterial cell.

Lecture 4

 by Prof.

On subtopic : Genetic Transfer and Recombination

Its all about

1. Transformation : Gene transfer from one bacterium to another as 'naked' DNA in solution

• Griffith's experiment

2. Transduction : Donor DNA transfer is madiated by a virus

• Generalized -->

• Specialized -->

3. Conjugation :
                                    -Transfer involve cell to cell contact
                                    -Conjugative plasmid is the donor cell
