Elements and Compounds

103.7K
Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.
Elements
Elements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...

Periodic Classification of the Elements

58.8K
The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

Key Elements for Plant Nutrition

24.1K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Elements: Chemical Symbols and Isotopes

125.5K
A chemical symbol is an abbreviation used to indicate an element or an atom of an element. For example, the symbol for mercury is Hg. The same symbol is used to indicate one atom of mercury (microscopic domain) or to label a container of many atoms of the element mercury (macroscopic domain).
Some symbols are derived from the common English name of the element; others are abbreviations of the name in another language — Latin, Greek or German. For example, the symbol for aluminum (common name)...

Area of Science:

  • Genomics
  • Epigenetics
  • Molecular Biology

Background:

  • Eukaryotic genomes contain abundant repetitive sequences, including transposable elements (TEs).
  • TEs are mobile genetic elements influencing genome evolution and gene function, requiring strict control mechanisms like epigenetic silencing.
  • Epigenetic regulation of TEs can indirectly affect nearby genes, potentially driving rapid phenotypic adaptation.

Purpose of the Study:

  • To highlight the importance of considering repetitive genomic sequences, particularly TEs, in the context of epigenetic modifications.
  • To emphasize the role of TEs in genome evolution and their interplay with epigenetic regulation.
  • To discuss the implications of TE-mediated epigenetic changes for organismal adaptation.

Main Methods:

  • Review of existing literature on transposable elements and epigenetic regulation.
  • Analysis of the impact of TE mobilization on epigenetic landscapes.
  • Discussion of bioinformatic tools for studying TEs and their epigenetic effects.

Main Results:

  • TEs are a significant component of eukaryotic genomes, impacting genome evolution and gene expression.
  • Epigenetic silencing is a primary mechanism for controlling TE activity.
  • Epigenetic regulation of TEs can lead to the epigenetic modification of nearby genes, influencing phenotypic adaptation.

Conclusions:

  • Repetitive genomic sequences, especially TEs, must be considered when assessing the global impact of epigenetic modifications.
  • TEs play a critical role in shaping epigenetic landscapes and facilitating rapid adaptation.
  • Bioinformatic tools are essential for investigating the complex interactions between TEs and epigenetic regulation.
