More than 40% of the world's Catholics live in Latin America-but Africa has seen the biggest growth in Catholic congregations in recent years. Latin America accounts for 483 million Catholics, or 41.3% of the total Catholic population. Of the 10 countries in the world with the most Catholics, four are in Latin America.
DNA cloning is the process of making multiple, identical copies of a particular piece of DNA. In a typical DNA cloning procedure, the gene or other DNA fragment of interest (perhaps a gene for a medically important human protein) is first inserted into a circular piece of DNA called a plasmid.
Molecular cloning generally uses DNA sequences from two different organisms: the species that is the source of the DNA to be cloned, and the species that will serve as the living host for replication of the recombinant DNA.Molecular cloning methods are central to many contemporary areas of modern biology and medicine.In a conventional molecular cloning experiment, the DNA to be cloned is obtained from an organism of interest, then treated with enzymes in the test tube to generate smaller DNA fragments.olecular cloning methods are central to many contemporary areas of modern biology and medicine.
