HCS_21-22_Biology_Unit 4 Question 11 <> Q Q Review / ✓ Finish Test ABG Question 11 Bacteriophages are a type of virus that infects bacteria. Scientists have started to use these bacteriophages to move genetic information from one bacterium to another. Which characteristic of a virus is an advantage and why? A The ability to integrate its own DNA into the host's DNA makes it possible to transfer the integrated DNA to another organism. B The ability to utilize the hosts' protein synthesis machinery where copies of synthesized proteins remain stored. C The ability to only infect a limited range of hosts helps to transfer genetic material more efficiently. D The ability to assemble itself inside the host cell makes the transfer more efficient and independent ©2021 Illuminate EducationTM, Inc.
Question 8 6 pts Match the genetic medicine technique with its description. Crispr-Cas9 Choose) Gene Therapy Choose) low molecular weight compounds that can interact directly with disease-causing proteins to block the negative effects of disease-causing proteins, or to restore their proper functioning Gene switches technology that uses an enzyme to cut the DNA and then edit the defective gene at a precise location, RNA Interference technology that involves using small RNA segments to target mRNAs for destruction to reduce expression of a specific gene Small-molecule therapies technology that works by regulating the non-coding sequence to either prevent genes linked to diseases from being turned on, or by keeping beneficial genes turned off Exon skipping technology that uses a viral vector to provide functioning copies of a gene into a cell to produce a functional protein technology that changes the primary RNA transcript of a gene by causing the splicing machinery to 'skip over a segment to remove the mutation
Question 1 Which statement best describes gene expression? O The process where genes are transcribed into RNA and then translated to make proteins. O The shape of a protein determines its function. O The process that converts the information in the mRNA into proteins. O The flow of genetic information from RNA to DNA to protein.
efpod wsela Explain how the field of science can attract many different types of people with varying interests. Consider the following: o People who prefer to work alone or people who enjoy working with others o People who prefer quiet work or people who prefer adventure and excitement o People who want to travel or people who don't o People who want to work creatively or people who prefer logical, analytical thinking o People who enjoy math or people who don't This tool needs to be loaded in a new browser window Load Careers in Science in a new window
In Bradford Protein Assay, the underlying mechanism for the dye Coomassie Blue G-250 being used to measure protein concentration is O 1. The dye can bind to the backbone of the peptide in proportion to the size of a protein O 2. The acidic dye can bind to basic amino acid residues in a protein, and the binding causes a change in color from red to blue which can be measured spectroscopically 3. The dye can bind to the side chain of a protein in proportion to the number of the amino acid residues in a protein 04. All of the answers are correct

Question 1 1 pts If heat shocking works--and there's some evidence that it does not--it works by doing which of the following things? O It causes cells' membranes to cycle faster, bringing DNA bound to the outer surface into the cell. O It causes DNA to linearize, which is required for internalization. O It causes DNA to become methylated, which is required for internalization. O All of these are correct.

All changes saved 1. In a discussion on whether genetically modified foods (GMO's) are better for people, Simone's perspective is "I believe organic, or non-GMO, foods are healthier." Which point below is a point of disagreement? GMO foods support science rather than agriculture. Genetic modification allows plants to be hardier and healthier. Genetically modified foods have less diversity and less variety. Plants grown naturally have more nutrients.
