Question 1

Amniocentesis is preferred over chorionic villus sampling because recombinant DNA screening can be achieved with amniocentesis but not with chorionic villus sampling.

Accepted Answer

The statement is false. Recombinant DNA screening can actually be achieved with chorionic villus sampling (CVS) as well as amniocentesis. The choice between the two procedures is usually based on factors such as the timing of the procedure, the risk of miscarriage, and the specific medical condition being screened for.

Question 2

Drosophila is a unique candidate for genetic engineering because it is the one prokaryote about which we have a great deal of genetic information.

Accepted Answer

Drosophila is actually a eukaryote (not a prokaryote) and it is not unique in terms of genetic information available. There are many other species, including humans, that have extensive genetic information available for genetic engineering.

Question 3

Alleles that differ by as little as a single nucleotide can be distinguished by synthetic probes known as ________.

Accepted Answer

The answer of Alleles that differ by as little as...

Question 4

Can human genes be patented?

Accepted Answer

The answer of Can human genes be patented?...

Question 5

It is likely that new methods of delivering vaccines will be developed so that traditional injection will be less frequent.

Accepted Answer

Many researchers are working on developing alternative methods for delivering vaccines such as nasal sprays, microneedles, and edible vaccines. These methods can be more convenient and less invasive for patients.

Question 6

Describe,in general terms,the aims of gene therapy.

Accepted Answer

The answer of Describe,in general terms,the aims of gene therapy....

Question 7

Biotechnology has yet to produce a single useful product for a human health condition.

Accepted Answer

Biotechnology has produced numerous useful products for human health conditions, including insulin for diabetes, antiviral drugs for HIV/AIDS, and cancer treatments such as Herceptin and Avastin.

Question 8

Genes in their natural state cannot be patented.This policy allows research and use of natural products for the common good.What argument might be presented in favor of patenting genes or gene products?

Accepted Answer

The answer of Genes in their natural state cannot be...

Question 9

Direct-to-consumer provides an accurate assessment of physiological and behavioral circumstances within patients that will eventually replace the need for routine visits to the doctor.

Accepted Answer

While direct-to-consumer technologies may provide insights into an individual's physiology and behavior, they cannot completely replace routine visits to a doctor for proper diagnosis and treatment of medical conditions. Physicians are trained to interpret multiple factors beyond just physiological measurements to provide a comprehensive, personalized approach to patient care.

Question 10

Rational drug design involves the synthesis of specific chemical substances that affect specific gene products.

Accepted Answer

Rational drug design uses an understanding of the molecular structure and function of a target protein or gene product to design drugs that interact with and modulate its activity. Synthesizing specific chemical substances that affect specific gene products is a key aspect of this process.

Question 11

In the past decades,direct-to-consumer (DTC)genetic tests have become widespread.Are such tests approved by the Food and Drug Administration?

Accepted Answer

The answer of In the past decades,direct-to-consumer (DTC)genetic tests have...

Question 12

There is a fear that preconception genetic testing may lead to "designer babies." What historical practice comes to mind regarding the production of such babies?

Accepted Answer

The answer of There is a fear that preconception genetic...

Question 13

One of the problems associated with the generation of transgenic plants is that the ecological parameters of many plants are not completely understood.

Accepted Answer

Despite the extensive research that has been conducted on transgenic plants, there are still ecological parameters that are not fully understood. This lack of understanding can result in unintended consequences and potential ecological risks associated with the release of transgenic plants into the environment.

Question 14

The Genetic Testing Registry is designed to restrict public access to a variety of genetic processes.

Accepted Answer

The Genetic Testing Registry is actually designed to provide public access to information on genetic tests and related processes. Its purpose is to promote transparency and facilitate research and clinical decision-making.

Question 15

The Human Genome Project seeks to rid the human population of genetic disease.

Accepted Answer

The Human Genome Project aimed to map and understand all the genes of human beings, not specifically to rid the population of genetic diseases, although understanding genetic diseases better was one of the potential applications of the research.

Question 16

A restriction fragment is generated by the action of a restriction enzyme (endonuclease).

Accepted Answer

A restriction fragment is indeed generated by the action of a restriction enzyme. The restriction enzyme cleaves DNA at specific recognition sequences, generating fragments that can be separated by gel electrophoresis.
