DNA ProcessesSlide2

Objectives

Be able to explain the processes of DNA replication, transcription and translation

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

Translation
