MCAT BIO REVIEW
aldosterone does what - answer ✔✔-increase sodium reabsorption in D-tubule
mitotic spindle is composed of - answer ✔✔-microtubules
Which of the following do NOT have proteins with a nuclear localization signal?
I. E. coli
II. Homo sapiens
III. Fungi
IV. Archaea - answer ✔✔-C is correct. E. coli, a bacteria, and archaea do not have nuclei, and thus do not
have a need for nuclear localization signal on their proteins. Homo sapiens and fungi are eukaryotes
with nuclei.
Which of the following correctly lists a pair of analogous structures and a pair of homologous structures,
respectively?
A.
The wing of a bee and the wing of a bird; the wing of a bird and the leg of a bird
