This week (9-13 Nov), we started the class on Monday by learning about new topic, which is DNA replication, translation and transcription. We start of with DNA replication. DNA replication is needed for reproduction and to provide heredity for the next generation. They replicate first before forming a code. The codes are later used to make protein. The replication process is helped with DNA polymerase, which is an enzyme that add extra bases to create 2 DNA strands for replication. DNA polymerase also add nucleotide to the new parent strand. They cannot read if there is no code. Helicase cut the hydrogen bond so that the DNA could separate for replication. The process is done on the replication fork. The gyrase enzyme make sure the DNA is not tangled back and keeps it open. DNA ligase make sure the bonding is correct. On Tuesday, we continue our topic and move on to DNA transcription and translation. Transcription and translation is a part of protein synthesis, and it is important since everything that we have in our body is made of protein. There are three types of RNA for protein synthesis which is mRNA that functions to carry message from nucleus to ribosome, tRNA that functions to bring amino acid to ribosome, and rRNA that functions to bring mRNA and tRNA together. Transcription process is to make mRNA from DNA code and it happens in nucleus. Translation later happens in ribosome, where the mRNA travels from nucleus to there through cytoplasm. In cytoplasm, the mRNA will meet tRNA. Later, in ribosome, the protein will be made. On Friday, Ms. Disty provide us a scavenger hunt workshop where we are given DNA codes and must translate it to mRNA in order to match it with the words spread around that will later form a sentence. Its a good and fun workshop since it allows us to move and not just sit around and listen. Sometimes, its good to be able to move around.
