protein synthesis

• what are the three types of RNA in protein synthesis

  rrna ,trna and mrna
• what are the two stages of proteins synthesis in order

  transcription and translation
• What is transcription?


  the synthesis of an RNA molecule from a DNA template
• what is the first stage of transcription in protein synthesis

  the genetic code for a specific protein is copied
• where does transcription take place

  inside the nucleus
• what happens in transcription after the genetic code for a specific protein is copied

  a complementary strand of mrna is formed from one template strand
• what happens in transcription when a complementary stand of mrna is formed

  the mrna leaves the nucleus via the nuclear pore and travels to the ribosome
• what happens in translation

  the mRNA is decoded and protein is made
• Where does translation take place?

  at the ribosome
• what is the first stage of translation

  the genetic code is translated into a polypeptide
• what happens in translation when the genetic code is translated into a polypeptide

  amino acids that correspond to the codons on the mrna are brought to the ribosome by trna
• what happens in transcription when the trna has transferred the amino acids

  the amino acids join together to form a polypeptide chain
