protein synthesis notes
- ribonucleic acid = rna
- rna is a single spiral
- rna contains genetic code like dna
- dna uses rna to give instructions to the rest of the cell usually to make proteins
- proteins are complex cells that do a lot of things
- one proteins only job is to let food into the cell membrane
- proteins are the basis for most cell functions
- in order to make a protein dna has to give rna the instructions, and then a protein can be made
- mRNA or messender rna
- the ribosomes can't read the recipes encoded in the mRNA, so they need tRNA or transfer RNA to decode the instructions
- ribosomes are partly made up of rRNA or ribosomal RNA (the most common type of RNA in a cell)
- RNA can also be in viruses like HIV, where RNA does the same job as DNA
- first life on earth was based on RNA instead of DNA
- early life = RNA world
- forms evolved from RNA into DNA
- protein synthesis is the production of protein
- Urasill is in RNA instead of Thymine
- translation is when messenger RNA is decoded by transfer RNA
- transcription is when messenger RNA copies the code from DNA
