Replication
DNA makes an exact copy of itself
Unzips
DNA polymerase unzips the DNA by breaking the weak hydrogen bonds that hold nitrogen bases together
Nucleotides added
In the middle of the unzipped DNA new nucleotides are added to each sideSlide4
Replication
Two molecules of DNA are formed
Each has 1 original DNA strand and 1 new strand (semi-conservative)Slide5
Practice and ExplainSlide6
Genes to Proteins
DNA contains all the genetic information for your body and every body cell has the same DNA
Cells look differently because they use different parts of DNA (genes) to make different proteins
List five different types of cells in your body and what you think they need to be able to doSlide7
Transcription
Writing and sending the “script”
DNA can’t leave the nucleus, sends a message
DNA transcribes
messengerRNA
(remember T is replaced with U)
Transcribe this message into text talk.
You are so smart. You make me smile. Laughter.Slide8
TranscriptionSlide9
Translation
Changing the script to the language of proteins
mRNA travels to the ribosome
Ribosome “reads” the mRNA by using codons (3RNA nucleotide that code for amino acids)
These codons match up with an anti-codon on a
transferRNA
Amino acids are assembled into proteins with peptide bondsSlide10
