RNA Use this power point to help you complete notes for interactive notebook
2
RNA Name: Ribonucleic acid
Nitrogen bases: A-U-C-G (adenine, uracil, cytosine, guanine) Structure: single - strand of nucleotides Sugar: ribose (5-carbon sugar) Function: to carry the DNA code to the ribosomes Number of types: 3 Names of the types: mRNA, tRNA, and rRNA Codon: 3 nitrogen bases that code for an amino acid Transcription; transferring DNA code onto mRNA Why is RNA important? Without RNA there would not be instructions for making proteins at the ribosomes in cells.

List the differences DNA RNA 1. Single RNA/double DNA 2. Uracil (RNA)
1. Single RNA/double DNA 2. Uracil (RNA) Thymine (DNA) 3. Ribose = RNA sugar Deoxyribose = DNA sugar 4. GAUC = RNA bases GATC = DNA bases
4
List the similarities DNA RNA 1. PHOSPHATE/SUGAR SIDES
1. PHOSPHATE/SUGAR SIDES 2. MADE OF NUCLEOTIDES 3. 5-CARBON SUGAR 4. NUCLEIC ACIDS
5
3 NITROGEN BASES on mRNA THAT CODE FOR AN AMINO ACID
Nucleic Acid Single-stranded Made in nucleus as a result of transcription Travels to ribosome with transcribed DNA code Called messenger RNA What is codon? 3 NITROGEN BASES on mRNA THAT CODE FOR AN AMINO ACID
6
rRNA Made of a large and a small unit that come
together for protein synthesis Found in the cytoplasm Translates the mRNA code to amino acid code in making proteins Called ribosomal RNA
7
tRNA Found in the cytoplasm Carries amino acid to ribosome
Small coiled RNA with three unmatched bases Found in the cytoplasm Carries amino acid to ribosome Called transfer RNA AMINO ACID tRNA ANTICODON
8
Use proper base pairing to complete DNA and mRNA
11
Summary for making proteins
TRANSCRIPTION → mRNA →TRANSLATION → PROTEIN
12
CHECK OUT THESE LINKS TO BETTER UNDERSTAND THE PROCESSES INVOLVED IN MAKING PROTEINS.
