What is the flow of information in a cell? (Otherwise known as the central Dogma) |
DNA (transcription) RNA (translation) Polypeptide |
|
|
What steps are involved in protein synthesis? |
1. Transcription 2. Translation |
|
|
What is transcription? |
The synthesis of RNA from DNA template - uses mRNA |
|
|
What is translation? |
Synthesis of polypeptides according to the strand created in transcription |
|
|
What are the differences in protein synthesis in cell types? |
prokaryotes: transcription and translation may occur simultaneously
eukaryotes: transcription occurs in the nucleus. Translation occurs in the cytoplasm |
|
|
What is the start codon? |
AUG - signals translation starts |
|
|
What are the three stop codons? |
UAA, UAG, UGA - signals translation to stop |
|
|
What are the steps involved in transcription? |
1. RNA polymerase binding and initiation of transcription 2. Elongation of the RNA strand 3. Termination of transcription |
|
|
What are the components involved in translation? |
mRNA, tRNA, and ribosomes |
|
|
What are the steps involved in translation? |
1. Initiation 2. Elongation 3. Termination |
|
|
What are the three steps involved elongation? |
1. Codon recognition (mRNA moved into A site after mRNA bonds to anticodon) 2. Peptide bond formation 3. Translocation |
