BIOL200 Simutext questions and Answers all
100% Correct
is RNA consumed (destroyed) as it is translated into a polypeptide? - ✔✔No, the
information in RNA is used, but the RNA molecule is not consumed
when does the polypeptide begin folding? - ✔✔during translation
what must be present in the hexokinase gene? - ✔✔a region that codes for the
hexokinase gene
an area that indicates where to start transcription
an area that indicates where to end transcription
which strand of DNA is used by RNA polymerase to make the RNA? - ✔✔template
strand
what happens to the DNA during transcription? - ✔✔one strand of DNA is copied into
RNA
which of the following statements about the RNA produced by transcription is true?
RNA is double stranded
RNA can base pair with DNA
RNA and DNA use the same bases - ✔✔RNA can base pair with DNA
is the transcription start site apart of the promoter? - ✔✔no
, what is true about promoters?
all promoter sequences for an organism are identical
promoters are the first part of the gene to be transcribed
promoters indicate where RNA polymerase attaches the DNA
promoters can be found at the 5' end of DNA strand - ✔✔promoters indicate where
RNA polymerase attaches the DNA
what molecule contains promoters? - ✔✔DNA
The DNA below represents a short sequence in the middle of a gene. What will the RNA
sequence be when this stretch of DNA is transcribed?
5′-ATGGC-3′ coding strand
3′-TACCG-5′ template strand - ✔✔5'-AUGGC-3'
in what direction does transcription proceed relative to the promoter? - ✔✔away
from it (downstream)
how are the RNA transcript, template strand and coding strand related? - ✔✔the
RNA sequence is most similar to the coding strand of DNA because they are both
complementary to the template strand
A single DNA molecule can contain thousands of genes, and each of these has its own
terminator. How are terminators helpful for the overall process of gene expression? -
✔✔without terminators, a huge amount of DNA would be transcribed at once,
resulting in a giant RNA transcript with too much information
where along the gene does RNA polymerase begin transcription? - ✔✔near the
promoter
