This electron microscopy image shows the posterior pole of a Drosophila oocyte, and superimposed on it is a projection of the movement of oskar mRNA in this region, recorded from a different oocyte at the same developmental stage.

What are the bare essentials of life, the indispensable ingredients required to produce a cell that can survive on its own? Can we describe the molecular anatomy of a cell, and understand how an entire organism functions as a system? These are just some of the questions that scientists in a partnership between the European Molecular Biology ...

Abstract The reference human genome provides an adequate basis for biological researchers to study the relationship between genotype and the associated phenotypes, but a large push is underway to sequence many more genomes to determine the role of various specificities among different individuals that control these relationships and to enable the ...

Genetic Programming : An Introduction : On the Automatic Evolution of Computer Programs and Its Applications Export Abstract Imagine a world in which computers program other computers based on strategies borrowed from biology and natural selection.

Abstract Understanding gene regulation has been and remains one of the major challenges for the molecular biology community.

Abstract Antibodies represent the end product of an exquisitely complex biological process including recombination, somatic hypermutation, affinity maturation, and self-tolerance, culminating in binding reagents directed against a vast repertoire of antigens.

Bacteria don't have easy lives. In addition to mammalian immune systems that besiege the bugs, they have natural enemies called bacteriophages, viruses that kill half the bacteria on Earth every two days.

When cells are confronted with an invading virus or bacteria or exposed to an irritating chemical, they protect themselves by going off their DNA recipe and inserting the wrong amino acid into new proteins to defend them against damage, scientists have discovered.

Main Category: Blood / Hematology Also Included In: Lymphoma / Leukemia / Myeloma Article Date: 25 Nov 2009 UK scientists have generated the first mouse model of 5q- syndrome, a human blood disorder, demonstrating the feasibility of creating chromosomal deletions in mice in order to study the genetic origins of such conditions.

Abstract A central issue in molecular biology is understanding the regulatory mechanisms that control gene expression.

We've looked before at the work of MIT biology research affiliate Joe Davis, whose passion is the melding of science and art.

Appearing in the Nov. 27, 2009, issue of JBC A key question in the origin of biological molecules like RNA and DNA is how they first came together billions of years ago from simple precursors.

A team led by Penn State's Ross Hardison, T. Ming Chu Professor of Biochemistry and Molecular Biology, has taken a large step toward unraveling how regulatory proteins control the production of gene products during development and growth.

Viruses are well known for attacking humans and animals, but some viruses instead attack bacteria.
