Peptide bond formation via dehydration reaction. When two amino acids form a dipeptide through a peptide bond, [1] it is a type of condensation reaction. [2] In this kind of condensation, two amino acids approach each other, with the non-side chain (C1) carboxylic acid moiety of one coming near the non-side chain (N2) amino moiety of the other.

Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction.Two genetic markers that are physically near to each other are unlikely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be more linked than markers that are far apart.
[5] Because there is a small probability of recombination at any location along a chromosome, the frequency of recombination between two locations depends on the distance separating them. [citation needed] Therefore, for genes sufficiently distant on the same chromosome, the amount of crossover is high enough to destroy the correlation between ...
An isopeptide bond is the linkage between the side chain amino or carboxyl group of one amino acid to the α-carboxyl, α-amino group, or the side chain of another amino acid. In a typical peptide bond, also known as eupeptide bond, the amide bond always forms between the α-carboxyl group of one amino acid and the α-amino group of the second ...
Peptoid. Peptoids (root from the Greek πεπτός, peptós "digested"; derived from πέσσειν, péssein "to digest" and the Greek-derived suffix -oid meaning "like, like that of, thing like a ______," ), or poly- N -substituted glycines, are a class of biochemicals known as biomimetics that replicate the behavior of biological molecules ...
Meiosis is ubiquitous among eukaryotes. It occurs in single-celled organisms such as yeast, as well as in multicellular organisms, such as humans. Eukaryotes arose from prokaryotes more than 2.2 billion years ago [ 1 ] and the earliest eukaryotes were likely single-celled organisms. To understand sex in eukaryotes, it is necessary to understand ...
The replication fork is a structure that forms within the long helical DNA during DNA replication. It is produced by enzymes called helicases that break the hydrogen bonds that hold the DNA strands together in a helix. The resulting structure has two branching "prongs", each one made up of a single strand of DNA.
