A. DNA polymerase IB.. A. DNA polymerase IB.. DNA ligaseD.. DNA transformation occurs when an organism incorporates DNA from the environmentD.. DNA polymerase III can only add to the 3´ end of a strandC.. The single DNA strands could not be held open. The two DNA strands are oriented in parallel (5'-to-3')C. Purines bind to pyrimidinesD.. DNA primaseD.. DNA ligase. DNA primase.d.. DNA ligase.. Telomeres are composed of specific DNA sequences, but they are not made by the replication complex. During replication of a linear DNA molecule, the leading strand can be completely replicated, but when the last RNA primer is removed from the lagging strand, DNA polymerases cannot replace it with DNA. In DNA, adenine always pairs with thymine and guanine always pairs with cyrosine, we refer to this pattern of base-pairing as complementary, which means that although the strands are not identical, they each can be used to specify the other by base-pairing if the sequence of one strand is ATGC, then the complementary strand sequence must be TACG.

Genetics is the scientific study of inherited variation. Human genetics, then, is the scientific study of inherited human variation.

But our interest in human genetics does not stop at the boundaries of the species, for what we learn about human genetic variation and its sources and transmission inevitably contributes to our understanding of genetics in general, just as the study of variation in other species informs our understanding of our own.. One benefit of studying human genetic variation is the discovery and description of the genetic contribution to many human diseases.. For example, the development of recombinant DNA techniques () rapidly transformed the study of human genetics, ultimately allowing scientists to study the detailed structure and functions of individual human genes, as well as to manipulate these genes in a variety of previously unimaginable ways.. Key among these techniques are restriction analysis and molecular recombination, which allow researchers to cut and rejoin DNA molecules in highly specific and predictable ways; amplification techniques, such as the polymerase chain reaction (PCR), which make it possible to make unlimited copies of any fragment of DNA; hybridization techniques, such as fluorescence in situ hybridization, which allow scientists to compare DNA samples from different sources and to locate specific base sequences within samples; and the automated sequencing techniques that today are allowing workers to sequence the human genome at an unprecedented rate.. To determine whether an individual possesses a mutation in the gene, a scientist first obtains a sample of DNA from the person's blood, as well as a sample of DNA that does not contain a mutation in that gene.. The human genome comprises about 3 × 10 9 base pairs of DNA, and the extent of human genetic variation is such that no two humans, save identical twins, ever have been or will be genetically identical.. As shows, modern genetic analysis of a human disease begins with mapping and cloning the associated gene or genes.. Mapping and cloning a gene can lead to strategies that reduce the risk of disease (preventive medicine); guidelines for prescribing drugs based on a person's genotype (pharmacogenomics); procedures that alter the affected gene (gene therapy); or drugs (more...). As indicates, the Human Genome Project (HGP) has significantly accelerated the pace of both the discovery of human genes and the development of new health care strategies based on a knowledge of a gene's structure and function.. The last few years of research into human genetic variation also have seen a gradual transition from a primary focus on genes associated with single-gene disorders, which are relatively rare in the human population, to an increasing focus on genes associated with multifactorial diseases.. candidate gene Gene, located in a chromosome region suspected of being involved in a disease, whose protein product suggests that it could be the disease gene in question.. Human Genome Project (HGP) International research project to map each human gene and to completely sequence human DNA.

An elevated CRP test in an otherwise normal person without evidence of an infection predicts an increased long-term risk of cardiovascular disease by identifying the inflammatory changes associated with accumulation of macrophages and other inflammatory cells in an unstable atheromatous coronary artery plaque.. Many blood coagulation factors are produced in the liver, and their concentrations in the blood are reduced in patients with liver disease.. B. Clumps of sickled red cells block blood vessels when blood oxygen content is reduced, which impedes blood flow to vital organs.. Because of the serious complications that can occur in some infected persons, the Centers for Disease Control and Prevention recommends that certain groups of high-risk individuals be tested for asymptomatic HCV infection.
