As an example, telomere length is rebuilt in cloned cattle. When donor nuclei from either cultured adult cells or fetal cells were used, in both cases telomerase activity was reprogrammed at the blastocyst stage, resulting in telomeres similar in length to age-matched controls. Applications of cloning by nuclear transfer The impetus behind cloning, like other developments in basic science, was to seek new fundamental knowledge, not to make legions of clones. However, there are a number of commercial and medical interests in cloning by nuclear transfer. These include the cloning of transgenic animals, cloning prize farm animals or race horses, cloning pets Focus box The transgene carried in the donor nucleus was designed to express human clotting factor IX in sheep milk. The disease hemophilia B is caused by low levels or a complete absence of this blood protein, which is essential for clotting. Neor was included for the selection of cells with the transgene stably integrated in their genome. The promoter sequence directs tissue-specific expression in the mammary gland. As noted in Section Other researchers are interested in the cloning of agriculturally important animals that are transgenic for a particular trait of interest. Another application is xenotransplantation — the use of genetically modified pigs as a source of organs suitable for transfer to humans. Cloning of prize animals Animal cloning has the potential to overcome the limitations of the normal breeding cycle. Animal breeders have an interest in maintaining and rapidly propagating elite herds of animals with superior traits, such as cows with high milk production or a champion racehorse. A prize animal is not generally identified until it matures, so differentiated adult cells must be used for cloning.

However, Weaver's text is almost too rich in experimental detail for many undergraduate audiences. Enter Lizabeth Allison's text, Fundamental Molecular Biology, which nicely brings students up to date in the core ideas and findings of molecular biology with a solid infusion of real experimental data to help students appreciate how knowledge is obtained in molecular biology. Although Fundamental Molecular Biology is not as detailed and exhaustive in presenting important experiments as Weaver's text, many instructors will appreciate the balance between experimental discussions and factual information.

The strengths of Fundamental Molecular Biology also include comprehensive tables, interesting boxes discussing the molecular basis of several diseases, and relatively short chapters. Even though each chapter is broken up into many subsections, it maintains an easy readability not found in many other texts.

Fundamental Molecular Biology

Fundamental Molecular Biology is divided into 17 chapters covering the typical areas of molecular biology. The first five chapters review basic genetics, the tenets of molecular genetics, and provide a solid overview of nucleic acid structure. The meat of the text begins in the next two chapters with the presentation of DNA replication, repair, and recombination, followed by two chapters on recombinant DNA technologies and other tools for analyzing gene expression.

Particular nice in Chapter 11 is the integration of fundamental mechanisms of eukaryotic transcription with nuclear structure and in Chapter 15, a thorough introduction to genetically modified higher animals only three of 33 pages cover plants.

All the other chapters of the text are solid, though it is in these that one sees the personal biases of the author in content coverage.

Also, the section of the range of cellular processes in which RNA participates is too terse. Fundamental Molecular Biology's principle weakness is its selectivity of topics that is inevitable in a book of this modest size.

Selectivity inevitably leads to omissions; so, it is also important to point out what is missing in this book.

Quantitative analysis in molecular biology is almost completely absent, which is unfortunate since quantitative approaches are becoming increasingly important to understand basic molecular phenomena such as thermodynamics of DNA—DNA or DNA—protein interactions, kinetics of binding of transcription factors and RNA processing factors, topological considerations of DNA replication, as well as systems approaches to combinatorial control of gene expression.

Indeed, Chapter 3 is archaic, focusing on observations about genome organization one might have seen in a textbook 20 years ago.

Molecular biology is the study of molecular underpinnings of biological activity. It studies the structure, function, processing, regulation, interactions and evolution of biomolecules. Its most famous subfield, molecular genetics , studies the processes of replication , transcription , translation , and genetic mechanisms of cell function.

The central dogma of molecular biology where genetic material is transcribed into RNA and then translated into protein , despite being oversimplified, still provides a good starting point for understanding the field.

The picture has been revised in light of emerging novel roles for RNA.

In the early s, the study of gene structure and function, molecular genetics , has been among the most prominent sub-fields of molecular biology. Increasingly many other areas of biology focus on molecules, either directly studying interactions in their own right such as in cell biology and developmental biology , or indirectly, where molecular techniques are used to infer historical attributes of populations or species , as in fields in evolutionary biology such as population genetics and phylogenetics.

There is also a long tradition of studying biomolecules "from the ground up" in biophysics.

For more extensive list on nucleic acid methods, see nucleic acid methods. Main article: Molecular cloning Transduction image One of the most basic techniques of molecular biology to study protein function is molecular cloning. A vector has 3 distinctive features: an origin of replication, a multiple cloning site MCS , and a selective marker usually antibiotic resistance.

Located upstream of the multiple cloning site are the promoter regions and the transcription start site which regulate the expression of cloned gene.

This plasmid can be inserted into either bacterial or animal cells. Introducing DNA into bacterial cells can be done by transformation via uptake of naked DNA, conjugation via cell-cell contact or by transduction via viral vector.

Introducing DNA into eukaryotic cells, such as animal cells, by physical or chemical means is called transfection. Several different transfection techniques are available, such as calcium phosphate transfection, electroporation , microinjection and liposome transfection. The plasmid may be integrated into the genome , resulting in a stable transfection, or may remain independent of the genome, called transient transfection.
