Concept explainers
The figure that follows shows part of a modified screen shot of part of the human genome as displayed on the UCSC Genome Browser. A through G map the sequences within individual cDNA clones to the genome sequence. Refer to the key in Fig. 10.3 if you need help in interpreting this diagram. Pay close attention to the vertical widths of the icons indicating exons.
How many annotated genes do you think are present in this region of the human genome?
For all annotated genes in this region, indicate whether they are transcribed in the direction from centromere to telomere or from telomere to centromere.
How many promoters are suggested by the data? Approximately where are these promoters located?
How many different proteins are encoded by the DNA sequences in this region?
What is unusual about this region of the human genome?

He gathered a group ofthe same species of plants, gave them the same amount of water, anddid the test for the same amount of time. Only the color of light waschanged.

OA. TIM22 OB. TIM23 C. OXA OD. Mia40 OE SAMarrow_forwardQUESTION 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.arrow_forwardFor 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.arrow_forward
