TRANSCRIPTION Flashcards
is the turning on or activation of a
gene.
GENE EXPRESSION
The process in which information encoded in a DNA molecule is copied into an mRNA molecule.
TRANSCRIPTION
Where does transcription take place?
NUCLEUS
When does Transcription starts?
WHEN DNA DOUBLE HELIX BEGINS TO UNWIND NEAR THE GENE TO BE TRANSCRIBED
How many strands of the DNA is transcribed?
ONE
________ assemble along the unwound DNA strand in a complementary sequence.
RIBONUCLEOTIDES
What enzyme catlyzes TRANSCRIPTION?
POLYMERASES
Which enzyme catlyzes the formation of rRNA?
POLYMERASE I
Which enzyme catylzes the formation of mRNA?
POLYMERASE II
Which enzyme catalyzes the formation of tRNA as well as one ribosomal subunit?
POLYMERASE III
