Definition: Epigenetics are the changes in the gene expression which are not caused by changes in the DNA sequences‚ meaning it a change in the phenotype but not the genotype. It is the study of the genes that are possibly inheritable. The environment you live in plays a key role in epigenetics and how your genes are expressed. How does epigenetics have anything to do with digestion? A chemical tag is something that can alter a gene expression. It attaches onto the DNA and blocks transcription.

MARKETING DEFINITION Market is managing profitable costumer relationship. The goal of marketing is to attract new costumers by promising superior value and to keep and grow current costumers by delivering satisfaction. Marketin is a social process by which individuals or groups obtain what they want and need through creating and exchanging product s and value with others. In a business context Marketing is the process by which companies create value for costumers and build strong relationship

of an individual. e.g. tanning makes skin darker‚ exercise alters build‚ nutrition influences height. Genotype is associated with a range of phenotypic possibilities due to environmental influences. Norm of reaction – the phenotypic range of a genotype influenced by the environment. (generally the broadest range is seen for polygenic characters) e.g. hydrangea flowers of the same genotype can range from blue-violet to pink depending on the acidity and aluminum content of the soil. e.g. temperature

Neurofibromatosis is an autosomal dominant genetic disorder that causes tumors to form in and on the brain‚ spinal cord‚ and nerves. This disorder is diagnosed by a number of tests‚ such as physical examinations‚ CT scans‚ MRI’s‚ and genetic testing. Researching medical and family histories can also be helpful. Neurofibromatosis cannot be cured; however‚ treatments may help. Treatments can include chemotherapy‚ radiation therapy‚ or surgeries‚ such as laminectomies and spinal fusions. Some people

Epigentics is a natural process that occurs within the body that activates and deactivates certain parts of a person’s genome expressing different genes. This process occurs during early human development for purposes of cell differentiation while still in the embryonic state‚ but scientists have also found that this cycle continues throughout a person’s life. Epigenetics helps to explain the balance between nature and nurture in phenotypic expression. Methyl groups are attached to certain base pairs
Premium DNA Genetics Gene
A gene is a long sequence of nucleotides on a DNA molecule. A mutation is a change in the amount of an organism’s genetic material and when a change in genotype produces a change in phenotype‚ the individual affected is said to be a mutant. A gene mutation involves a change in one or more of the nucleotides in a strand of DNA. The sequence of nucleotides in a gene controls the order in which amino acids are made into a protein‚ therefore if the sequence of nucleotides in a gene is altered by a mutation
