cell survive, cell grow and division, cell differentiation, and apoptosis - answers✔✔Which of the
following is/are a global response(s) to signaling (or lack of signaling in some case(s) discussed
in lecture? Select the best single answer.Incorrect cell differentiation
i is FALSE, and ii is TRUE. - answers✔✔Which of the following is correct with regard to the two
statements below?
i = Adult stem cells are pluripotent.
ii = When a stem cell divides one of the two resulting cells is a stem cell.
All of the above (regulated cell division, signaling between cells, and apoptosis) - answers✔✔In
Xenopus laevis, proper tissue development requires which of the following?
Signaling in normal development and cellular damage, especially DNA damage - answers✔✔As
discussed in lecture, apoptosis can occur in response to what? Select the best single answer.
210 - answers✔✔As discussed in lecture, approximately how many cell types are there in
human cells, at least for our comparative purposes this semester? Choose the best single
answer.
10^14 - answers✔✔Approximately how many cells are there in the human body?
The shape of the cytoskeleton - answers✔✔What determines the shape of a eukaryotic cell?
Ectoderm - answers✔✔From which germ layer does the neural tube form during Xenopus
development?
, i is TRUE, and ii is FALSE. - answers✔✔Which of the two statements below is/are TRUE, and
which is/are FALSE?
i = Exon shuffling occurs at the level of DNA in the genome; whereas, splicing occurs at the level
of RNA.
ii = In lecture, we discussed the modular construction of some genes and the evolution of genes
(and proteins) by the addition of domains. As described in lecture, this process occurs in
prokaryotes and eukaryotes
That enhancers can act over long distances - answers✔✔Which property of eukaryotic gene
regulatory regions, as discussed in lecture, allowed for the evolution complex regulatory
regions?
When properly folded, the N- and C- termini often point in opposite directions. -
answers✔✔Which of the following is/are often properties of protein domains?
i is FALSE, and ii is TRUE. - answers✔✔A version of the figure below was discussed in lecture.
Which of the two statements below is/are TRUE, and which is/are FALSE?
i = α-globin gene A3 is more closely related to myoglobin gene M1 than it is to β-globin gene
B1.ii = β-globin gene B5 is more closely related to β-globin gene B1 than it is to α-globin gene
A1.
Both i and ii are TRUE. - answers✔✔Which of the following statements is/are TRUE, and which
is/are FALSE?
i = As described in lecture, a polyclonal antibody contains many different antibodies, each of
which recognizes a distinct epitope on the surface of an antigen.
ii = As described in lecture, when purifying a protein of interest one needs an assay that is
specific for that particular protein.
