Chapter 12, Problem 3TYK
Summary Introduction
To review:
On the basis of the data for the genotype, the types of gametes formed and their proportion, for the following pairs:
a. AABB
b. AaBB
c. Aabb
d. AaBb
One gene has the alleles A and a whereas another gene has the alleles B and b. A and B represent the dominant alleles while a and b represent the recessive alleles.
Introduction:
When a homozygous allelic pair divides, it forms the same genes with both coding either for dominant genes or for recessive genes. When a heterozygous allelic pair divides, it forms two genes that code for dominant genes and recessive genes. In the case of independent assortment, each characteristic separate into gametes independently when there are two or more characteristics to be inherited.

QUESTION 9
An animal cell has been wounded and has a small rupture in its plasma membrane. Which of the following is more likely to happen next?
OA. The cell rapidly cleaves by cytokinesis.
OB. The rate of receptor-mediati endocytosis is increased.
OC. The rate of exocytosis is increased.
OD. The rate of pinocytosis is increased.
For the a subunit of a trimeric G protein,
A. a G-protein-coupled receptor GPCR) acts as a guanine nucleotide exchange factor (GEF), whereas a regulator of G protein signaling (RGS) can act as a GTPase-activating protein
(GAP).
B. a GPCR acts as a GAP, whereas an RGS can act as a GEF.
C. both a GPCR and an RGS can act as a GEF.
O D. both a GPCR and an RGS can act as a GAP
OE. None of the above.
A cell expresses a transmembrane protein that is cleaved at the plasma membrane to release an extracellular fragment. The fragment binds to receptor proteins on nearby cells and
activates signaling pathways resulting in altered gene expression patterns in the cells. What form of intercellular signaling does this represent?
OA. Contact-dependent signaling
B. Paracrine signaling
OC. Synaptic signaling
D. Endocrine signaling
E. Autocrine signaling
