Protein Synthesis: Transcription and Translation

What is the order of the steps in protein synthesis?

• Translation, then Transcription

• Transcription, then Replication

• Transcription, then Translation

• Translation, then Replication

Put the steps the cells take using DNA to create proteins synthesis in the correct order

• Transcription

  -->

• Protein

• RNA

• Translation

  -->

• DNA

During transcription, a sequence of ​ (a)   is copied onto a strand of ​ (b)   so that it can leave the ​ (c)   to find a ​ (d)   .

• DNA
• mRNA
• nucleus
• ribosome

During translation, the code from ​ (a)   is read by the ​ (b)   and translated into a sequence of ​ (c)   .

• mRNA
• ribosome
• amino acids

What is the job of tRNA?

• Carry amino acids to the ribosome during protein synthesis
• Facilitate cell division
• Store genetic information
• Transcribe DNA into RNA
