BIOL 250 Final Exam UPDATED ACTUAL Questions and
CORRECT Answers
, what types of biological molecules replicate DNA? proteins
what processes occur during interphase? DNA replication
organelle replication
RNA synthesis
protein synthesis
is DNA, RNA, or both produced by DNA polymerase? DNA
you observe that Gene X is highly expressed in neurons high levels of DNA methylation in intestinal cells
but is not expressed in intestinal cells. If you could assess
the chromatin surrounding Gene X in both cell types,
what would expect to observe?
Which of the following mutations would most likely pro-pro-asp-lys-lys-arg-lys-val
disrupt the nuclear localization of a protein?
Normal: Pro - Pro - Lys - Lys - Lys - Arg - Lys - Val
only ____ contains ribose RNA
molecules are made of _____ that are attached by isotopes / electrons
chemical bonds formed by sharing, gaining, or losing
_________.
how is M-phase rapidly triggered by M-Cdks? M-cyclin/cdk complex is held inactive by phosphorylation and is rapidly activated
by Cdc25
protein domains are sequences of amino acids that are exons are shuffled to new genes
similar in many different proteins and lead to different
proteins that are made of similar 'parts'. what is the most
likely explanation for the evolution of protein domains?
rNA in cells differs from DNA in that _____________ it is single-stranded and can fold into a variety of structures
where would you predict a protein to be localized if it ER
has a chain of hydrophobic amino acids at the N-
terminus?
which of the following amino acids would you expect to serine
find on the surface of a protein?
