After the gel sets, DNA is loaded into each of the 96 lanes that run the length of the 30 cm gel. 

As the DNA pieces move through the gel, the sequencing machine reads the order of DNA bases and stores this information in its computer memory.]]> 2022-01-04 21:40:00 UTC https://padlet.com/1039720/cm1b7xtg9it8eesa/wish/1975183772 1039720 https://padlet.com/1039720/cm1b7xtg9it8eesa/wish/1975186400 There are 3 main steps to PCR

1. Denaturation: In this step the two strands of DNA are heated up causing the strands to separate.

2:Annealing: Primer (which is a short sequence of DNA) binds to the DNA strand and causes Polymerisation, in this process free nucleotide form to make a strand of DNA.   

3:Extension: The original strands are used as templates for new strands. Firstly DNA polymease joins the free DNA nucleotide together. Order is determined by the original strands sequence of nucleotide. The result of PCR are two double stranded sequences of the DNA, both containing 1 strand of the original strand and 1 new strand. 

This process is then repeated many times and in 2-3 hours a billion copies can be made. ]]> 2022-01-04 21:42:31 UTC https://padlet.com/1039720/cm1b7xtg9it8eesa/wish/1975186400 1041875 https://padlet.com/1039720/cm1b7xtg9it8eesa/wish/1975186841 Gel Electrophoresis is a technique used to separate DNA fragments through utilizing its size and its charge.

- Single Gene sequencing: sequencing all exons of a gene, including the non coding zones to check for the mutations of certain genes that has over 1000 mutations such as FBN1 gene]]> 2022-01-04 21:48:55 UTC https://padlet.com/1039720/cm1b7xtg9it8eesa/wish/1975193167 1046590 https://padlet.com/1039720/cm1b7xtg9it8eesa/wish/1975203474 maintains lab equipment and supplies, collecting and processing biological specimens for analysis, preparing solutions, conducting experiments, and research data collection and entry.

The gel is made out of a polysaccharide called agarose. The gel allows the DNA molecules to travel within in. At one end of the electrophoresis tank there are well, where the DNA will be placed. 
Once the gel has been loaded into the gel box, the DNA samples are loaded into the wells. Next the power is turned on and the fragments travel through the gel. 
By the end, the fragments should now be separated by size. The fragments that traveled the farthest are the small fragments and the large fragments will remain close to the wells.
Once the fragments have been separated, the gel can be examined and compare the size of the bands. Bands is a defined line of DNA on gel. Bands contain several DNA fragments. The gel can be stained with dye and put under a UV light, indicating the DNA present along the gel. The single fragment DNA will not appear on the gel. 
By utilizing a DNA ladder, we can compare the bands to determine its approximate size.]]> 2022-01-04 22:03:45 UTC https://padlet.com/1039720/cm1b7xtg9it8eesa/wish/1975208667 1046590 https://padlet.com/1039720/cm1b7xtg9it8eesa/wish/1975210307 interact with these agencies on behalf of their company, for example, by preparing reports and hosting regulatory reviews.

"Fragments of interest" are created by the enzymatic restriction, which can be cloned.

DNA is then isolated and purified from RNA, proteins, and structures such as cell membranes. DNA is retrieved from the nucleus and is known as Genomic DNA. Restriction enzymes are then used to cut up specific DNA sequences in order to create a new sequence from DNA fragments.

DNA fragments are then ligated to create a recombinant plasmid DNA molecule. Restriction enzymes also help with the adhesion process within the fragments
