viruses and last lecture of microbial genetics ~~

21^st November 2014

8.00-10.00 am

Today I learnt about Viruses with Dr Wan.

We have no game for today.

Acellular agents are :

·         Viruses

·         Viroids

·         Satellites

·         Prions

Viruses are the major cause of disease. There are some important of viruses :

·         Important members of aquatic world

·         Important in evolution

·         Important model system in molecular biology

There are two type of viruses :

·         Envelope viruses

·         Non-envelope viruses

There are three types of capsids :

·         Helical

·         Icosahedral

·         Complex

Viral multiplication involve several steps :

·         Attachment to host cell

·         Entry and

·         uncoating (degrading cell membrane)

·         synthesis protein

·         assembly

·         release

10.00am-12.00 pm

Today is the forth lecture with Prof Khatty on Microbial Genetic. The more we studied this topic the more difficult I found it. HUH L

Today I learnt about genetic transfer and recombinant.

Genetic recombinant refers to the rearrangement of DNA from separate groups of genes.

Genetic transfer in prokaryotes involve :

·         transformation

·         transduction

·         conjugation

Types of plasmid :

·         dissimilation plasmid

·         conjugative plasmid

·         R factors

There are three distinct types of transposons :

·         Class II Transposons consisiting only of DNA that moves directly from place to place.

·         Class III Transposons also known as Miniature Inverted-repeats Transposable

·         Class I : Retrotransposons that

ü  First transcribe the DNA into RNA

ü  Use reverse transcriptase to make a DNA copy of the RNA to insert in a new location.

End our class today with steady and sleepy. Wehuuuu HAHA, BYE! J

third day with Proff Khaty~~

18^th November 2014

Today is the third lecture with Prof Khatty on Microbial Genetic. The more we studied this topic the more difficult I found it. HUH L

Today I learnt about Mutation.

Mutation is any inheritable change in the base sequence of DNA.

There are two types of mutation :

1.       Base substitution

·         Silent

·         Missense

·         Nonsense

2.       Frameshift mutation

·         Insertion or deletion

·         Shift in the reading frame

Mutation rate is the probability that a gene will be mutated in a single generation

Mutation frequency is the frequency at which a specific kind of mutation (or mutant) is found in a population of individuals.

There are types of mutagen such as :

·         Base analogues

·         Chemical mutagen

·         Radiation

·         Intercalating agents

That’s all from me, till we meet again. Assalamualaikum

Prof. Katthy second lecture's ~~

14^th November 2014

Today is our second lecture with Prof. Khatty.  Today our class went to SACC for the NUCEL.  Alhamdulillah, they won silver!! I’m very proud of them.

There are two modes of Gene Expression:

1.       Constitutive expression

2.       Inducible expression

There are three possible places in the production of an active gene :

1.       As transcriptional regulation

2.       As translation regulation

3.       Post-transcriptional or post-translational regulation mechanism

In this lecture Prof teach us on how the mechanism of repression works. Yet, I miss you Dr Wan. J

Till we meet again….. Bye!

Prof Katthy first lecture's ~~

10^th November 2014

Today is our first lecture with Prof. Khatty. HEHE unusually no one of our class voice out when Prof. asking about the microbial genetics, all of us silence as silence as we can. HAHA

Today class was so bored because we just straight away learning, no more chatting no more cakes no more foods no more games and no more Dr Wan, hmmmmm L

From this lecture, I know that :

·         Genome :  genetic information in cell

·         Chromosomes : structures containing DNA that carry genetic information

·         Genes : segments of DNA that code for functional product.

·         Genetic information :  coded in the sequence of bases

·         Genotype : genetic composition of an organism

·         Phenotype :actual expressed properties of an organism

Functions of DNA :

·         Storage of genetic information

·         Self-duplication and inheritance

·         Expression of genetic

And we also learnt about the mechanism of the Transcription and Translation  J

So, till meet again! XOXO

Eleventh lecture of Microbes ~

Assalamualaikum w.b.t

Today is the 11^th lecture! Our class starts on 8.15 a.m at 1.2. Today Dr. Wan have to attend meeting and give us task on eukaryotes.

My group has to do game on cell membrane of eukaryotes. So we decided to do it in role-play. After discussing we move to 1.4 and start our game.

1.       Poison box-(flagella, cilia, cytoplasm)

2.       Role-play -(cell membrane)

3.       Spin your ribosomes -(ribosomes)

4.       Dart quizzes – (Nucleus)

5.       Jump lysosome jump! –(lysosome)

6.       Bingo- (vacuole)

7.       Lucky bottle-(Smooth Endoplasmic Recticulum)

8.       Wheel decide – (rough Endoplasmic Recticulum)

9.       Golgi penalty (Golgi apparatus)

10.   Quiz oh Quiz (mitochondria)

Those games have to involve all group members. We enjoyed that day damn much! Instead of playing games we also get the information about the structure of eukaryotes.

That’s all from me, till we meet again. XOXO J

Tenth day of lecture~~

31^st October 2014

Today is our tenth day of lecture. We have to study first about fungi and algae.

What I’ve learnt about algae. The classifications of algae are:

• Chrysophyta
• Euglenophyta
• Pyrrhophyta
• Charophyta
• Chlorophyta
• Phaeophyta
• Rhodophyta

There are five types of fungi that are :

• chytrids (Chytridiomycota) 
• zygote (Zygomycota)
• sac (Ascomycomycota)
• club (Basidiomycota)
• Microsporidia

As Dr.Wan said, our class wants to celebrate October’s birthday boy and girl, today she brought us homemade cakes! His husband bakes the cakes by himself. So WOW! HEEHEE

And today also we've submitted two crossword that are Crossword of Algae and Crossword of Fungi!

Till we meet again, Bye!

Thank a Microbes~~

27^th October 2014

Today is our presentations’ day. We’re all nervous but happy too because all the hard works comes to final.

Me, myself was too excited when the augmented reality can well run.

After all the presentation ended, I get too much information about microbes. As I know bacteria is harmful to human. After the presentation I know that not all of the bacteria were harmful to human, there also beneficial that they give us.

We also had been judged by others lecturer. And it come to climax, I feel very nervous to present our microbe to all the judges. When it come to the`` lecturer have to ask us question’’ about the microbes, it was the hardest and most scary part for me and my group members.

I think this is a good beginner for us as first year students. And I really hope that my group would not win this competition. HAHA. It just because we’re afraid and worry when we have to present it in front of the judges.

This is our lovely microbe! Bacillus megaterium  XD

                            

                                                      Bacillus megaterium

Till we meet again, Bye!
