Chapter 11 11.2 From DNA to Protein
DNA can make RNA RNA = Ribonucleic Acid RNA Single strand that helps build protein
Differences DNA RNA Double stranded Sugar = Deoxyribose4 Nitrogen Bases Adenine Guanine Cytosine Thymine RNA Single stranded Sugar = Ribose 4 Nitrogen Bases Adenine Guanine Cytosine URACIL (attaches to adenine
3 Types of RNA Messenger RNA (mRNA)Brings information from the DNA in the nucleus to the cell’s cytoplasm
3 Types of RNA Ribosomal RNA (rRNA)Clamps onto mRNA to assemble amino acids in correct order
3 Types of RNA Transfer RNA (tRNA)Transfers amino acids to ribosomes to be assembled into proteins
Types of RNA
Steps in Protein Synthesis1. DNA sends out code 2. mRNA carries code to ribosome 3. tRNA pick up amino acids 4. tRNA carries amino acid to ribosome 5. force together to make protein
Transcription Results in the formation of one single stranded RNA (Transcription DNA makes RNA)
Codon Each set of three nitrogen bases in mRNA representing an amino acid is known as a codon.
Nitrogen base order in mRNA determines the type and order of amino acids in a protein. 64 possibilities
The DNA Connection.
RNA (Ribonucleic Acid) and Transcription Chapter 10.
Protein Synthesis Ordinary Level. Lesson Objectives At the end of this lesson you should be able to 1.Outline the steps in protein synthesis 2.Understand.
A. There are three key differences between RNA and DNA 1. RNA is single stranded : DNA is double stranded 2. RNA is made of the sugar Ribose – DNA is.
Nucleic Acids DNA vs. RNA
The Structure of RNA RiboNucleic Acid
RNA: Structure and Function. RNA FUNCTION Function: RNA reads blueprints (DNA) & makes protein.
From Gene to Protein. DNA Review n Is made of nucleotides. n Contains deoxyribose sugar n Thymine, Guanine, Cytosine, Adenine n Is a double stranded molecule.
Q2 WK8 D3 & 4. How does DNA’s message travel OUT of the nucleus and INTO THE CELL, where the message gets expressed as a protein??? This is known as…
RNA Use this power point to help you complete notes for interactive notebook.
Section 11-2 From DNA to Proteins. Enzymes control all the chemical reactions of an organism Thus, by encoding the instructions form making proteins,
RNA & Protein Synthesis.
DNA Chapter 12. DNA DeoxyriboNucleic Acid Sugar = deoxyribose Adenine + Thymine Guanine + Cytosine Double-stranded helix with alternating sugars and phosphate.
RNA and protein synthesis. RNA Single strand of nucleotides Sugar is ribose Uracil instead of thymine.
Chapter 12 – DNA and Proteins DNA Structure: DNA is made of many smaller subunits called nucleotides.
Chapter 12 Making Proteins. Differences between RNA and DNA DNA = double strand; RNA = single strand RNA contains Ribose instead of deoxyribose. RNA uses.
DNA RNA DNA Replication & Transcription Translation.
RNA and Protein Synthesis
RNARNA. PROTEIN SYNTHESIS The BIG Picture……. Objective: By the end of class today students will be able to change a DNA sequence into an PROTIEN sequence.
