Biology Honors: RNA Test – Advanced Assessment on RNA Structure, Function,
and Gene Expression


Operon - ANS ✔✔group of genes operating together



Off - ANS ✔✔Active repressors turn ___ (on or off) the process of transcription when Lactose is
not present.



active repressor - ANS ✔✔These bind to the operator; they block operator and prevent
transcription



promotor - ANS ✔✔specific region of a gene where RNA polymerase can bind and begin
transcription



operator - ANS ✔✔region where active repressors may bind and stop the process of
transcription



ribose - ANS ✔✔DNA contains DEOXYRIBOSE as a sugar, whereas RNA contains __________ as a
sugar.



Uracil - ANS ✔✔Which RNA base replaces the DNA base, Thymine?



single stranded - ANS ✔✔Is RNA single-stranded or double stranded?



RNA is single stranded, contains Uracil instead of Thymine, and contains Ribose instead of
deoxyribose - ANS ✔✔What are three differences between DNA and RNA?
