Epigenetics and Chromosome

Oncology is a branch of medicine that deals with the prevention, diagnosis, and treatment of cancer. A medical professional who practices oncology is an oncologist Cancer survival has improved due to three main components: improved prevention efforts to reduce exposure to risk factors improved screening of several cancer and improvements in treatment.The three main divisions:

A brain tumor occurs when abnormal cells form within the brain There are two main types of tumors cancerous (malignant) tumors and benign (non-cancerous) tumors Cancerous tumors can be divided into primary tumors, which start within the brain, and secondary tumors, which most commonly have spread from tumors located outside the brain, known as brain metastasis tumors All types of brain tumors may produce symptoms that vary depending on the part of the brain involveds. The most common primary brain tumors are

The recent development of high-throughput technologies has led to an explosion of biological data and has enabled mining biomarkers and drug targets in a more systematic way. Bioinformatic and biostatistical approaches are skilled at dealing with large data sets and therefore widely used in mining disease biomarkers and drug targets in this “omic” era

By the tip of the last century, it absolutely was known that DNA by itself doesn't determine all characteristics of an organism, including humans. The environment, stress one perceives, and nutrition, to call some, play a big part in determining the response of an organism, the utmost amount because the DNA itself. Thus, it's known now that both nature and nurture play equally important roles within the responses observed both at the cellular and organism levels.

Gene mapping describes the methods used to identify the locus of a gene and the distances between genes Gene mapping can also describe the distances between different sites within a gene. The essence of all genome mapping is to place a collection of molecular markers onto their respective positions on the genome.

Ranges of epigenetic idea affect our genetic programme. The inter-generational transmission of epigenetic marks is supposed to manage via four principal means dramatically differ in their information content: DNA methylation, histone modifications, microRNAs and nucleosome positioning.

Although brain tumours are rare compared with other malignancies, they are responsible, in many cases, for severe physical and cognitive disability and have a high case fatality rate. The diagnosis is made by a combination of imaging and histological examination of tumour specimen. Contrast-enhanced MRI is the gold standard imaging modality and provides highly sensitive anatomical information about the tumour.

Genome editing is a method that lets scientists change the DNA of many organisms, including plants, bacteria, and animals. Editing DNA can lead to changes in physical traits, like eye color, and disease risk. Scientists use different technologies to do this. The first genome editing technologies were developed in the late 1900s. More recently, a new genome editing tool called CRISPR, invented in 2009,

A primary transcript is the single-stranded ribonucleic acid (RNA) product synthesized by transcription of DNA, and processed to yield various mature RNA products such as mRNAs, tRNAs, and rRNAs.

Structural inheritance is an often-neglected form of nongenetic inheritance. This is in contrast to the transmission of digital information such as is found in DNA sequences, which accounts for the vast majority of known genetic variation. Structural inheritance was discovered by Tracy Sonneborn, and other researchers, during his study on protozoa in the late 1930.                                   .

nucleosome positioning” broadly to indicate where nucleosomes are located with respect to the genomic DNA sequence. Although nucleosome positioning is a dynamic process, sequencing-based mapping approaches identify the positions of individual nucleosomes in a single cell at a specific time.
