1 Word of the Day Mutation Quiz RNA notes Video

2 RNA Differences from DNA: One-stranded Instead of Thymine, RNA has Uracil Three types of RNA: mRNA –carries copies of DNA from nucleus to the cytoplasm.(messenger RNA) tRNA – folded RNA that connects to mRNA to connect amino acids. (transport)

3 More RNA rRNA-(ribosomal RNA)takes the ribosome's where proteins are made Transcription – the process by which genetic material is copied from DNA to RNA.

4 Transcription(in the nucleus) RNA polymerase unzips DNA and copies it into RNA. A’s connect with U’s and G’s connect with C’s. The starting point of transcription is known as the Promoter, the end is known as the terminal signal. After transcription the mRNA moves into the cytosol for protein synthesis.

5 Protein synthesis: From DNA to You Proteins are made from chains of amino acids, the order of these AA’s determines the structure of a protein. The genetic code is a way of reading the sequence of amino acids. A codon is a combination of three nitrogen containing bases in a row. Each codon codes for a different amino-acid.

6 Translation(in the cytoplasm) A start codon tells a ribosome to start translating the mRNA. A stop codon tells it to stop. Anti-codons on tRNA match up with codons to start connecting amino acids to make proteins. A to U, G to C.
