1. Objective: to understand RNA and transcription and translation 12.3

2. To decode DNA it needs to be changed into RNA The purpose of DNA is to instruct the cell to make amino acids which connect to make proteins RNA- ribonucleic acid

3. 3 differences: The sugar is ribose (not deoxyribose) Normally single stranded (not double) Contains Uracil (not Thymine)

4. 3 types of RNA Messenger RNA- carry copies of instructions from DNA to the rest of the cell Ribosomal RNA- at the ribosome (where proteins are formed) Transfer RNA- transfers amino acids to ribosome as it is coded by the mRNA

5. Transcription- copying DNA into RNA Genetic Code- each 3 letters of RNA is a codon which can be translated into a specific amino acid
