Base Excision Repair01:54

Base Excision Repair

26.2K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

Lewis Acids and Bases

48.3K
In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond.
A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...

DNA Base Pairing

Weak Base Solutions

24.9K
Some compounds produce hydroxide ions when dissolved by chemically reacting with water molecules. In all cases, these compounds react only partially and so are classified as weak bases. These types of compounds are also abundant in nature and important commodities in various technologies. For example, global production of the weak base ammonia is typically well over 100 metric tons annually, being widely used as an agricultural fertilizer, a raw material for chemical synthesis of other...

Ions as Acids and Bases

Salts with Acidic Ions
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:

Acids, Bases and Neutralization Reactions

63.7K
An acid-base reaction is one in which a hydrogen ion, H+, is transferred from one chemical species to another. Such reactions are of central importance to numerous natural and technological processes, ranging from the chemical transformations within cells or lakes and oceans to the industrial-scale production of fertilizers, pharmaceuticals, and other substances essential to the society.

Area of Science:

  • Nutrition Science
  • Dietary Assessment Methods
  • Scientific Communication

Background:

  • Recent commentaries debated the utility of memory-based dietary assessment methods (M-BMs).
  • Conflicting viewpoints emerged, necessitating a clear examination of the arguments presented.
  • Understanding these debates is crucial for advancing dietary assessment research.

Purpose of the Study:

  • To clarify claims made in four commentaries regarding M-BMs.
  • To analyze the data and claims supporting each argument.
  • To identify reasons for disagreement and propose pathways for progress.

Main Methods:

  • Systematic analysis of four commentaries on M-BMs.
  • Decomposition of arguments into data and claim components.
  • Categorization of data types used to support claims.

Main Results:

  • Identified key arguments and their supporting data from each commentary.
  • Highlighted differences in data types and interpretation contributing to the debate.
  • Pinpointed potential sources of disagreement between opposing viewpoints.

Conclusions:

  • The controversy surrounding M-BMs stems from differing interpretations of evidence and methodologies.
  • Further research should focus on standardizing data collection and analysis for M-BMs.
  • Collaborative efforts are needed to reconcile divergent perspectives and advance the field.
