Cancer-death on your doorstep ! | Health For You

The DNA is inserted into the host DNA where it may stay and be replicated for generation of cells. HIV is a harmful reterovirus and other reteroviruses cause cancer. These contain a gene which alters host cell division genes, switching them on and causing the cell to become malignant. ->DNA viruses contain DNA as their hereditary material. Some contain their own oncogenes which can cause uncontrolled cell division of host cells. ->Hereditary predisposition. About 5% of human cancers show a strong genetic predisposition. More than 40 types of cancer, including breast, ovary and colon cancers [more...]

New Paper Shows Enzyme-Controlled Movement of DNA Polymer Through ...

This paper addresses a key challenge for DNA strand sequencing: fine control of the translocation of the DNA strand through the nanopore, at a rate that is consistent and slow enough to enable accurate identification of individual DNA bases. The Nature Nanotechnology work shows for the first time that the motion of a strand can be controlled using electronic feedback and that an enzyme can move a strand against a field while located on top of the nanopore. "The techniques described in this paper are an advance towards electronic, single molecule DNA sequencing of DNA strands" said [more...]

Structure and mechanism of human DNA polymerase eta.

Structure and mechanism of human DNA polymerase eta. Nature. 2010 Jun 24;465(7301):1044-8 Authors: Biertümpfel C, Zhao Y, Kondo Y, Ramón-Maiques S, Gregory M, Lee JY, Masutani C, Lehmann AR, Hanaoka F, Yang W The variant form of the human syndrome xeroderma pigmentosum (XPV) is caused by a deficiency in DNA polymerase eta (Poleta), a DNA polymerase that enables replication through ultraviolet-induced pyrimidine dimers.

The Science: Gene Mutation

Gene Mutation In general mutation may be defined as a sudden change in the genetic material. In recent years the term mutation has generally been restricted to processes that result in a direct alteration of gene contents unrelated to observable chromosome changes. Thus, mutation at the level of nitrogenous base sequences of DNA, i.e., at the genetic level is called gene mutation or point mutation. According to strickberger, ‘point mutation or gene mutation has come to mean the process by which new alleles of gene are produced’. Gene mutation can arise spontaneously or they may be [more...]

Biology Animations: animation of DNA replication

The chain elongation reaction catalyzed by DNA polymerases is a nucleophilic attack by the 3’-OH group of the primer on the innermost phosphorus atom of the deoxynucleoside triphosphate. A phosphodiester bridge forms with the concomitant release of pyrophosphate. The subsequent release of pyrophosphate by pyrophosphatase helps drive the polymerization forward. ***Elongation of DNA chain proceeds 5’-to-3’ direction. ***Template directed enzyme also have nuclease activity.

Do you want to live forever? Scientist may have figured out how…

The ends of the chromosomes are capped by telomeres, long thought to have a protective function. Without them, the chromosomes would be shortened during each cell division, because DNA polymerase is unable to copy to the very end of one of the two DNA strands it is replicating.       In the early 1980s, after their fortuitous meeting at a Gordon Research Conference in 1980, Blackburn and Szostak discovered that telo­meres include a specific DNA sequence. Fired up by the novelty of each other's work, they devised experiments that seemed crazy at the time, even to themselves. Szostak took [more...]

How the Most Influential Scientists Alive Today Unraveled the ...

DNA has been extensively researched by scientists wishing to further understand the complex way in which life is biochemically formed. DNA contains the genetic information that composes nearly all living organisms. In the early 1950s, molecular biologist James D. Watson led his team of researchers to the ground breaking discovery that DNA is a double-stranded chain, also referred to as a double helix. Using models, he showed how matching nucleotide base pairs from the two DNA strands interlocked to form a double helix. He then showed how the strands separate during replication, and how each [more...]

Autism and schizophrenia: Scientists measure gene mutation rate ...

Mutations are alterations of the cell’s DNA that can occur because of errors in the DNA replication, which happen prior to cell division. Once DNA is changed, this mutation is passed down to a next generation. A mutation that is newly formed and therefore not inherited from either parent is called a de novo mutation. More information: The paper, “Direct Measure of the de novo Mutation Rate in Autism and Schizophrenia cohorts,” published in the American Journal of Human Genetics, was authored by Philip Awadalla, et al. http://www.cell.com/AJHG Source: [more...]

DNA Polymerase and other factors

DNA polymerase can add free nucleotides to only the 3’ end of the newly-forming strand. This results in elongation of the new strand in a 5'-3' direction. No known DNA polymerase is able to begin a new chain (de novo). DNA polymerase can add a nucleotide onto only a preexisting 3'-OH group, and, therefore, needs a primer at which it can add the first nucleotide. Primers consist of RNA and DNA bases with the first two bases always being RNA, and are synthesized by another enzyme called primase. An enzyme known as a helicase is required to unwind DNA from a double-strand structure to a [more...]

Importantly, we show that in the absence of the TP N-terminal domain the efficiency of ϕ29 DNA replication is severely affected. Moreover, the TP recruits the phage DNA polymerase to the bacterial nucleoid, and both proteins later are redistributed to enlarged helix-like structures in an MreB cytoskeleton-dependent way. These data disclose a key function for the TP in vivo: organizing the early viral DNA replication machinery at the cell nucleoid.

Dynamic DNA Helicase-DNA Polymerase Interactions Assure Processive ...

A single copy of bacteriophage T7 DNA polymerase and DNA helicase advance the replication fork with a processivity greater than 17,000 nucleotides. Nonetheless, the polymerase transiently dissociates from the DNA without leaving the replisome. Ensemble and single-molecule techniques demonstrate that this dynamic processivity is made possible by two modes of DNA polymerase-helicase interaction. During DNA synthesis the polymerase and the helicase interact at a high-affinity site. In this polymerizing mode, the polymerase dissociates from the DNA approximately every 5000 bases. The polymerase, [more...]

DNA replication is the process by which one double helix of DNA is duplicated into two identical double helices which are also identical to the mother DNA. Translation is taking the RNA just made and using it to make a protein. Translation takes place after transcription of the genetic code into mRNA has been started. Translation refers to protein synthesis, in which proteins are made by reading the sequence information after the mature and processed mRNA by a ribosome. To me, transcription still refers to transcribing from a recording. But I thought you might want to find out why you’re [more...]

What Does DNA Stand For in Science | Intelligent Mag

Before cells are divided, the chromosomes duplicate first; this is what we call replication of DNA. This is the division of cells which results in two cells that have to contain the same information like their mother-cell. There are four nitrogenous bases within the DNA molecule. Those are: Adenine, Cytosine, Thymine and Guanine. Genes are composed of bases. In case of DNA damaging, the sequence of DNA will be changed. This happens when there is mutagen factor involved. These mutagens are highly radioactive. The damage that occurs as a result of the radiation is determined by the mutagen [more...]

Protein Synthesis, DNA Replication - DNA Station

Protein Synthesis, DNA Replication DNA replication is the process of copying a double-stranded DNA molecule to form two double-stranded molecules. The process of DNA replication is a fundamental process used by all living organisms as it is the basis for biological inheritance. As each DNA strand holds the same genetic information, both strands can serve as templates for the reproduction of the opposite strand. The template strand is preserved in its entirety and the new strand is assembled from nucleotides — this process is called “semiconservative replication”. The resulting [more...]
