Bio-Electronic Engineering....

Assalamualaikum and hello to all the readers. We meet again this week because this week , we have to update another lecture that have we learned in this week class. This week all section 1 and section 2 students have been combined because there is no more workshop after this. So En Ridzuan doesn't conducted our class for this week and his place taken by DrAzran. This is our first class with him and we were very excited to start the class. For our first half of the class which started at 9.00 am, Dr Azran briefed to us the introduction of bioelectronic. 

This is the definition of bioelectronics.

• Bioelectronic is a recently coined term for a field of research that works to establish a synergy between electronics and biology.                                                                                                                        

Before that, Dr Azran did some revise on the topic that we have learned before this which is 

  

         1.Electric component.

             

                 2.Electric symbol.

   

                     3.Resistor

 

                         4.Impedance

            5.Series and Parallel circuit

                          6.Voltage divider.

    

After finished revised, Dr Azranbriefed to us the introduction of bioelectronics.

The picture below showed the eukaryotes cell.

After that, we also have learned about DNA.

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria 

The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.

DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.

An important property of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell.

This is the structure of DNA.

After 90 minutes , the lecture finished and Prof Kamal took the class.Dr Kamal lecture is just he wanna brief on the next assignment we have to do which is making a poster about the chapter we get.There are three types of area we have to do which is Industrial Automation System, Bioelectronic System and Embedded System. The dateline of this assignment is 27th November and it takes only 3 weeks to finish this assignment. Nevermind, we confident that we can finish it successfully.

I think that's all I wanna post for this week and until we meet again for another interesting lecture. I promise that I will share with all of the readers what we going to learn. That's all. Assalamualaikum.
