Answer Key
What occurs first, transcription or translation? Transcription
The main goal of transcription is to turn DNA into RNA.
Transcription occurs in the nucleus
Transcription consists of four parts: initiation, elongation, termination, and RNA
processing.
Bacteria use operons to decide what segment of DNA needs to be transcribed
while eukaryotes use transcription factors
RNA polymerase and the transcription factors bind to the DNA at the promoter
which has three parts. Draw it below.

How many strands of DNA are used for transcription? One One is called the
template strand because it’s used as a template to make the mRNA
and the other is called the coding strand because it’s sequence is similar to the
mRNA except U replaces the T.
A terminator sequence determines where in the DNA to stop transcription.
In what types of cells does RNA processing occur? Eukaryotes
What is added to the 5’ end of the mRNA? Cap
What is added to the 3’ end of the mRNA? Poly A Tail
How many snurps make up a splicesome? 4 What are the two components of a
snurp? Ribozymes and other proteins.
Introns are noncoding segments and are thus removed while exons are the mRNA
that is expressed.
