A. peer reviewed research articles on disease and the environment
B. the complete genome from a new species
C. bits of DNA from numerous species
D. many copies of cloning vector with different inserts

F. some DNA representing genes that are similar but differ in exact sequence
Some critics have warned that the use of gene therapy to correct genetic disorders will affect the course of human evolution. Evaluate this criticism in light of what you know about population genetics and evolution, distinguishing between somatic gene therapy and germ-line gene therapy.

- Bioinformatics is the science of using computational methods (specialized software) to decipher the biological meaning of information contained within an organismal system. If you have to identify a gene, for example from the fruit fly, that is of interest to you, and you would like to know whether the human genome contains a homolog (related gene) of the fruit fly gene, one tool you could use is a program called Group of answer choices RefSeq (species reference sequence) Excel BLAST (Basic Local Alignment Search Tool) GenBankarrow_forwardHumans and chimpanzees share about 98% of their DNA. What is DNA? What might be the role of regulatory genes in producing the anatomical differences between these two lineages? Give two examples of how the field of genetics has revolutionized biological science. What is polymerase chain reaction (PCR) and why is it important in genetics?arrow_forwardNow that cloning is possible, should it be used to clone animals that are near extinction? What are the possible ramifications of this when it comes to genetic diversity and size of the gene pool?arrow_forward
- Briefly describe two scientific problems that can be addressed using the data from DNA barcoding experiments.arrow_forwardMost scientists consider the Human Genome Project (HGP) to be the most significant scientific project of the 21st century. Choose the statements that describe the key findings of the Human Genome Project. A. There are 23 pairs of chromosomes that make up the human genome. B. DNA exists in a double helical form. C. There are approximately three billion base pairs in the human genome. D. The human genome contains approximately 25000 genes. E. The genetic information of a cell is stored in the form of DNA.arrow_forwardTo create genetically modified organisms (often called GMOS) scientists directly manipulate the genes of an organism, often by inserting or deleting one or more genes. The inserted gene is usually from another species. The purpose of this manipulation is to give the target organism and its offspring a new trait that improves it in some way. The improvement might, for example, give the organism higher vitamin content. The process is called genetic engineering. 1. What are genetically modified organisms? 2.

- A researcher used polymerase chain reaction (PCR) to test four individual nematodes for the presence of a mutation in Gene Y. When amplified, the fragments of DNA containing the mutated gene alleles were 250 base pairs long and the normal (wild type) alleles were 350 base pairs long. To identify the genotypes of the individual nematodes, the researcher used gel electrophoresis to visualize the PCR results. 1.000 bp 500 bp 300 bp 200 bp 100 bp Remember that these nematodes are diploid organisms and as such, inherited two copies of Gene Y. Which of the following statements is a correct analysis of these results a) Nematode As homozygous for this gene and has two copies of the mutated allele. O b) Nematode C is heterozygous for this gene and has one copy of the mutated allele and one copy of the normal (wild type) allele. O) Nematode D is heterozygous for this gene and has one copy of the mutated allele and one copy of the normal (wild type) allele. ) d) Nematode B is homozygous for this…arrow_forwardGive detailed Solution with explanation neededarrow_forwardA genetics research group has determined the sequence of a rat gene thought to be involved in controlling the fertilising ability of rat sperm. They believe a similar gene may control fertility in humans. Describe how what is known about the rat gene can be applied in PCR to clone the complementary human gene. You should explain the experimental approach taken and how it could confirm that the human gene in question does indeed correspond to the rat gene.arrow_forward
- What is a transgenic organism? a. an organism that has had its entire genome sequenced b. an organism that has genes from another species c. an organism that does not use DNA to specify proteins d. an organism with multiple copies of the same gene e. an organism that has been DNA profiledarrow_forwardA researcher examines genes for several proteins that are quite similar in both structure and function. He is interested in determining whether the genes form a multigene family and in working out which of the proteins arose first evolutionarily. What would be the BEST approach to take to address this question? Be careful to look for the best approach; some other approaches could also provide useful information while being less definitive. A. The researcher should sequence the genes and compare their sequences. The most similar genes are likely the most closely related, while those that have more base differences probably diverged earlier. B. The researcher should examine the functions of the proteins. Those with the most similar functions are the most closely related. C. The researcher should induce mutations in the genes to see how these affect the function. The most mutations needed to cause changes in the function of the protein, the older the gene. D.
