1. Transcription

2. Define the following Messenger RNA Ribosomal RNA Transfer RNA Transcription Codon

3. Morse Code

4. Genes and Proteins Read on pg. 294 what role proteins play How does DNA factor in?

5. RNA 3 chemical differences between DNA and RNA 1. Single strand 2. Sugar in RNA is ribose 3. Uracil (U) instead of thymine (T) “U R single”

6. Three types of RNA Messenger RNA (mRNA) Ribosomal RNA (rRNA) Transfer RNA (tRNA)

7. Messenger RNA (mRNA) RNA that transports information from DNA in the nucleus to the cell's cytoplasm

9. Ribosomal RNA (rRNA) RNA that makes up the ribosomes; Clamps onto mRNA and Uses it’s information to assemble amino acids in the correct order

11. Transfer RNA (tRNA) RNA that transports amino acids to the ribosomes to be assembled into proteins

13. Transcription Process in the cell nucleus where enzymes make an RNA copy of a DNA strand 1. Enzymes unzip the molecule of DNA 2. RNA nucleotides pair with complementary DNA nucleotides on a DNA strand

20. Amino Acids

21. The Genetic Code 4 nitrogen bases make up 20 amino acids (64 combos) This is the genetic code Separated into codons Set of three nitrogen bases that codes for an amino acid
