RNA Discovery

The discovery of RNA began with the discovery of nucleic acids by Friedrich Miescher in 1868 who called the material 'nuclein' since it was found in the nucleus.

RNA is usually synthesized from DNA. The synthesis usually requires one or more enzymes like RNA polymerase. The DNA strand is used as a template or guide on which the RNA is formed. Since RNA forms the proteins, this is the way the DNA maintains the blue print for all proteins without leaving the nucleus.

RNA Structure

RNA is a single stranded molecule containing a ribose sugar. It has a distinctive structure and, unlike DNA, there are variations and various types of RNA structures.

Anti-VEGF Therapies

Vascular endothelial growth factor (VEGF) contributes to several pathological processes and is therefore a popular target in the research and development of therapies for certain illnesses.

VEGF Clinical Significance

Vascular endothelial growth factor (VEGF) is a signal protein required for the formation of new blood vessels. Proteins from this family play important roles in various bodily process such as inflammation and wound healing, as well as contributing to disease processes when they are overexpressed.

VEGF Production

VEGF or vascular endothelial growth factor is a signalling molecule that promotes the formation of new blood vessels.

VEGF Mechanism

VEGF or vascular endothelial growth factor is a signalling protein made by cells that stimulates the formation of new blood vessels. There are several different classes of VEGF that play different roles in the body, both in normal bodily process and pathological processes.

VEGF Classification

VEGF (vascular endothelial growth factor) is a signal protein that promotes the growth of new blood vessels. VEGF forms part of the system that restores the blood supply to cells and tissues when they are deprived of oxygenated blood due to compromised blood circulation.

DNA Polymerase Families

The DNA polymerases are divided into seven families based on their sequence homology and crystal structure analysis. These include families A, B, C, D, X, Y and RT.

What is DNA Polymerase?

The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from one original DNA molecule. During this process, DNA polymerase “reads” the existing DNA strands to create two new strands that match the existing ones.

Stem Cell Patents

Three human embryonic stem cell patents are held by the Wisconsin Alumni Research Foundation (WARF) in the United States. These are based on University of Wisconsin scientist James Thomson’s pioneering research. The US Patent and Trademark Office (USPTO) had granted these patents in 1998 and 2001 (due to expire in 2015 and 2018).

DNA Evolution

DNA carries the genetic information of species and has been evolving over millions of years. Earlier studies of prehistoric and historical migrations of human populations were possible only by research on uncovered skeletal remains and fossils.

DNA Interactions with Proteins

DNA is a polymer that lies within the nucleus of all cells. DNA interacts with numerous proteins that perform their functions in conjunction with DNA.

DNA Biological Functions

DNA is vital for all living beings – even plants. It is important for inheritance, coding for proteins and the genetic instruction guide for life and its processes. DNA holds the instructions for an organism's or each cell’s development and reproduction and ultimately death.

DNA Chemical Modifications

DNA is the basic building block of the genes that form the instructions to the cells on their birth, maturity, functions and eventually death.

DNA Properties

DNA or deoxyribonucleic acid is the basic hereditary material present in all the cells of an organism and basically provides a blue print for the cell’s functions, growth, reproduction and death. The structure of the DNA called the double-stranded helical structure was first described by Watson and Crick in 1953.

What is DNA?

DNA is deoxyribonucleic acid. It is located in the nuclei of cells, which make up the body. Consequently, DNA can be considered as one of the building blocks of the body.
