Blog 7: Glycolysis

Glycolysis is the fundamental stage of cellular respiration because it is the most fastest energy maker to every living organism. They are anaerobic and they do not require oxygen which is a good thing so they don't need the need to do their stuff. The first part of cellular respiration is glycolysis. Glycolysis is anaerobic and they occur in the cytoplasm. It breaks down glucose into 3 carbon molecules called pyruvic acid. It produces 2 NADPH and 2 ATP. Why it takes place in the cytoplasm? It takes place in the cytoplasm because is where all the chemical reaction takes place.

Blog 6: GMOs

Why is GMO bad for us?

Well, GMO is really bad for us because of what it can do. It is unhealthy. It can leave a certain material and can cause long-term problems. These things are bacteria that can do harmful stuff to us. GMOs can cross pollinate and their seeds can travel forever. It is impossible to clean up and will be contaminated forever. The side effects on the GMO is unpredictable. It can produce new toxins and other such sort of harmful things. GMO can also harm living things and ruin crops. It can harm the environment really badly.

Why is GMO good for us?

They increase the need of food production for the starving countries. They reduce the pesticides and herbicides. The manipulate the foods so they can carry more good nutrients. Lastly they produce no oil at all.

Blog 5: How has DNA fingerprinting changed forensics?

DNA - means deoxyribonucleic acid. It is a molecule that encodes the genetic instructions used in the development of functioning organisms and other viruses.

How has DNA changed forensics?

DNA has changed forensics overtime because of its unique genetic signature. While using that we can read its genetic code and use it to identify the suspect and put him behind bars. The way we can use DNA fingerprinting is if the suspect leaves its DNA around. If we find his/her prints we can identify it. DNA fingerprinting began in the 1980's.

How do we use it?

We can use DNA to pick up the suspect's information. Scientists can pick up the information from the DNA and find the suspect's information. To use this you have to get bodily objects such as blood, skin, or hair.

Blog 4: Three Advantages of PCR

Three Advantages of PCR

PCR is a cloning process that can begin with a tiny amount of DNA and low MW fragments. The three advantages of PCR are:

  • can amplify STR in an amount needed to be successfully profiled
  • it is safe to prepare separate electrophoresis gels for ash process
  • can load onto the gel in equal amounts for each probe
