DNA Replication
Texte du Storyboard
- Hello
- Hello, what is your name?
- Matthew Messelson
- Aren't you the Matthew Messelson that suggested that DNA replicates?
- You said DNA replication is the process by which DNA makes a copy of itself during cell division.
- Yes, that is me.
- I can't remeber the steps to replication again, what are they?
- The first step is that the DNA "unzips", the second step is when little pieces of RNA come in and start replicating the DNA.
- the bases match with the free floating nucleotides present inside the cell following the nucleotide base pairing rules to establish the hydrogen bonding between a separated strand and a new matching strand. Step 4 is Termination process, no more DNA replication can happen at the end of the strand so the DNA looks through and checks for mistakes made through the DNA and RNA.
- Why is that all important to anyone but scientists?
- DNA replication is very important to everyone, it's how you grow! the DNA multiplies since you were just on single cell and now look you've grown into an adult human.
- What is the result to DNA replication?
- The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides.
