What functional group is found
on the 3’ end of DNA?
What functional group is found

What is meant by the term
coupled transcription/translation?
What is meant by the term
coupled transcription/translation?



Translation begins before transcription
has been completed
This only occurs in prokaryotes since
they do not contain a nucleus
In eukaryotes, transcription is
completed in the nucleus before
translation can take place in the
cytoplasm
What type of RNA contains
codons?
What type of RNA contain
codons?


Codons are found in messenger RNA
They are 3 base sequences that either
start translation, code for an amino
acid, or stop translation
What type of RNA contain
anticodons?
What type of RNA contain
anticodons?


tRNA
Anticodons
complementary base
pair to codons
What is the name of the enzyme
needed for transcription?
What is the name of the enzyme
needed for transcription?

RNA Polymerase
What is a promoter?
What is a promoter?

A specific DNA sequence that RNA
polymerase binds to, found at the
beginning of genes
