BIO. Exam 3 1403 TTU Questions &
Answers (Grade A+)
Transcription Stages -
correct answer ✅initiation, elongation, termination
Initiation -
correct answer ✅requires binding of RNA Polymerase to a region
called the promoter, starts when the double-stranded DNA
template is separated, through the breaking of hydrogen bonds, to
form the transcription bubbleThis step commits the RNA
polymerase to move down the DNA template and add nucleotides
to the growing RNA chain
How many distinct RNA polymerases does Eukaryotic cells require?
What is the name of the proteins they need? -
correct answer ✅3, Transcription Factors initiate transcription at
the promoter
Promoter -
correct answer ✅initiation requires binding the RNA polymerase
to this region
RNA polymerase II -
correct answer ✅responsible for transcribing the overwhelming
, BIO. Exam 3 1403 TTU Questions &
Answers (Grade A+)
majority of eukaryotic genes, This enzyme is located in the nucleus
and synthesizes all protein-coding nuclear pre-mRNAs
RNA polymerase I -
correct answer ✅is located in the nucleolus, a specialized nuclear
substructure in which ribosomal RNA (rRNA) is transcribed,
processed, and assembled into ribosomes, The rRNA molecules are
considered structural RNAs because they have a cellular role but
are not translated into protein. The rRNAs are components of the
ribosome and are essential to the process of translation.
RNA polymerase III -
correct answer ✅located in the nucleus. This polymerase
transcribes a variety of structural RNAs that includes the 5S pre-
rRNA, transfer pre-RNAs (pre-tRNAs), and small nuclear pre-RNAs
tRNA's -
correct answer ✅have a critical role in translation; they serve as
the "adaptor molecules" between the mRNA template and the
growing polypeptide chain. Small nuclear RNAs have a variety of
functions, including splicing pre-mRNAs and regulating transcription
factors.
