21/11/14  We have our class today with Dr Wan at 2.2 Biotech 2.We learn about virus.Virus is not living organism until take over host.Virus is major causes of disease.  Acellular Agents Viruses-protein and nucleic acid Viroids-only RNA Satellites-only nucleic acid Prions-protein only Example of disease cause by Prion is Kuru. Kuru occured in Papua New Guinea because of tradition to eat dead family member brain. Most virus is in hydrosphere Mostly in marine and sea. The virus can be grow in embryonated egg. pic from: http://www.virology.ws/wp-content/uploads/2009/12/viruses_in_eggs.jpg Virus is important in evolution.One of the evolution of virus is ebola virus.During 2008 the host is monkey but now the host is bat. Bacteriophages,bacterial virus kill only bad bacteria. It kill pathogenic bacteria in poultry. Before this I thought that virus only cause disease but now I know that virus also can also kill bad bacteria.ow I also know that virus have many

18/11/14     Today we learn about Mutation.Mutation is any inheritable change in the base sequence of DNA. A strain carrying such a change is mutant.Differ from parental strain in genotype and phenotype.Mutation can be spontaneous or induced. Spontaneous mutation-occurs without mutagens                                     -alters the structure of bases in DNA Induced mutation-chemical and physical agents to induced the mutation There are many types of mutations Base substitution-single base at one point in DNA sequence replace with different base Missence mutation Silent Mutations http://i0.wp.com/www.namrata.co/wp-content/uploads/2013/04/Point-mutations.png?resize=384%2C177 Nonsense Mutations http://www7.0zz0.com/2011/08/05/01/948870633.gif Frameshift mutatio Before learning about mutation in this class I thought that when a mutation a change always occur in term of product produce.After this class I got to know there a mutation happen but the

14/11/14  In the  morning we went to National University Carnival on E-learning at SACC, Shah Alam. We went there for supporting our friends who involve in the Carnival.We went there by bus. I get to see many booth from UPM and other university take part in the carnival in many field such as medicine, earth science, communication and many more.There are many new information that I get when visiting the booth. I also get to see many different way of learning during the carnival. I enjoys myself at the carnival. Thank to Dr Wan who bring we here and also congrats to our friends who manage to get Silver in the competition. In the evening we have class with Datin Khadijah at 1.3. We learn about Regulation of Gene Expression. Modes of Gene Expression -constitutive expression expressed at same rate all time -inducible expression gene expression changes in response to condition. Regulation of enzyme activity Feedback inhibition Allosteric inhibition

11/11/14             Today is our first class with Datin Khatijah. Class is at 1.4. We learn about Strucutre and Function Of Genetic Material.  Genome: genetic information in cell   Chromosomes:structures containing DNA that containing genetic information pic from: http://www.writework.com/uploads/7/74478/human-genome-genes.png Genes: segments of DNA that code functional product. DNA deoxyribonucleic acid made of nucleotides: -nitrogenous base , sugars and phosphate group Nucleic Acid pic from :http://images.tutorvista.com/cms/images/101/purines-and-pyrimidines.png We also learn about replication of Bacterial DNA In today class there are some information that has been study before this and there also a new information about genetics that have been learn through genetics.It helps me to recall back my memory on genetics learn before this and I was quite shock that actually the poress in replication of DNA is quite complicated than I thought before t

7/11/2014     Today class start at 8.15 am at 1.2.We are ask to make a game about eukaryotic structure that whole class can play.We we given time 1 hour.We start the game at 1.4 when Dr Wan come back from the meeting.There all 10 group that have divided among us.Each team get different organelle .This activity has make the classroom more fun.During the games,there are some questions I can answer and some question that I do not remember the answer.but we able to do all the games as a team.These games also make me know the fact about eukaryotic structure that I do not now and help to recall what had been learn before this.As for our group, we get the rough endoplasmic reticulum.We decide to do Wheel Decide.This game start with a few stationery is given to the student in class and a music is played.When the music stop the student with a stationery have to come to to roll the wheel and answer the question been ask.When do the game it also help me to recall about rough endoplasmic reticulu
