Protein Synthesus Flashcards
Protein synthesis
Transcription
Translation
Transcription
Relevant gene in DNA in nucleus, copied into mRNA
DNA unzips with DNA helicase
Sense strand=template, free RNA nucleotides complementary base pair to expose bases on strand, form hydrogen bonds.
RNA polymerase forms phosphodiester bonds between nucleotides
MRNA detaches from sense strand
2 DNA strands join together, back into helix
Spliceosomes remove introns
Transcription to translation
mRNA moves out through nuclear pore, attaches to ribosomes
Translation
tRNA with specific codon brings specific amino acid, complementary to triplet in ribosome
Empty tRNA leaves to pick up another specific amino acid, ribosome moves along 1 codon
Process repeated until ribosome reads stop codon
