Genomics

35.5K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Epigenetic Regulation

3.5K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Pharmacogenetics and Pharmacogenomics: Overview

253
Pharmacogenetics and pharmacogenomics examine how genetic factors influence an individual's response to drugs. While pharmacogenetics focuses on the impact of specific genetic variants on drug effects, pharmacogenomics takes a broader approach, studying how genetic variation across populations contributes to differences in drug responses. These fields aim to explain why individuals may experience varying levels of efficacy or adverse reactions to the same medication.Variability in drug...

Gene-Environment Interactions01:20

Gene-Environment Interactions

1.4K
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

Summary
This summary is machine-generated.

Epigenetics definitions vary, causing confusion. Proposing "memigenetics" for inherited cell activity states clarifies the field and distinguishes it from broader epigenetic modifications.

Area of Science:

  • * Molecular Biology
  • * Genetics
  • * Cell Biology

Background:

  • * The field of epigenetics is rapidly expanding, but its definition remains unclear.
  • * Historically, epigenetics described forces influencing gene action in cell differentiation.
  • * Current definitions debate whether epigenetics solely encompasses inherited gene activity states.

Purpose of the Study:

  • * To address the definitional ambiguity in the field of epigenetics.
  • * To propose a new term, 'memigenetics', for inherited chromatin activity states.
  • * To differentiate between inherited and transient gene activity modifications.

Main Methods:

  • * Literature review of historical and current epigenetics definitions.
  • * Conceptual analysis of the term 'epigenetics' and its prefix 'epi-'.
  • * Proposal of a new term, 'memigenetics', based on etymological and functional considerations.

Main Results:

  • * Significant disagreement exists regarding whether epigenetics should exclusively refer to inherited activity states.
  • * The term 'memigenetics' is proposed to specifically denote inherited chromatin activity states, emphasizing cell memory.
  • * This distinction would allow 'epigenetics' to be used more broadly, encompassing all modifications 'over' DNA.

Conclusions:

  • * Adopting 'memigenetics' for inherited states would resolve definitional disputes in epigenetics.
  • * The proposed term highlights the crucial role of cell memory in inheritance.
  • * This semantic refinement would enhance clarity and precision in molecular biology and genetics research.
