2. Homology (biology) - Wikipedia

   en.wikipedia.org/wiki/Homology_(biology)

   The term "homology" was first used in biology by the anatomist Richard Owen in 1843 when studying the similarities of vertebrate fins and limbs, defining it as the "same organ in different animals under every variety of form and function", [6] and contrasting it with the matching term "analogy" which he used to describe different structures ...

3. Sequence homology - Wikipedia

   en.wikipedia.org/wiki/Sequence_homology

   Sequence homology is the biological homology between DNA, RNA, or protein sequences, defined in terms of shared ancestry in the evolutionary history of life. Two segments of DNA can have shared ancestry because of three phenomena: either a speciation event (orthologs), or a duplication event (paralogs), or else a horizontal (or lateral) gene ...

4. Deep homology - Wikipedia

   en.wikipedia.org/wiki/Deep_homology

   In modern day biology, the depth of understanding deep homology has evolved into focusing on the molecular and genetic mechanisms and functions rather than simple morphology. Cancer stem cells (CSCs) are a population of cells within a tumor that have the ability to self-renew and differentiate into different cell types, similar to normal stem ...

5. Homology - Wikipedia

   en.wikipedia.org/wiki/Homology

   Homology (biology), any characteristic of biological organisms that is derived from a common ancestor Sequence homology , biological homology between DNA, RNA, or protein sequences Homologous chromosomes , chromosomes in a biological cell that pair up (synapse) during meiosis

6. Cellular homology - Wikipedia

   en.wikipedia.org/wiki/Cellular_homology

   Cellular homology can also be used to calculate the homology of the genus g surface. The fundamental polygon of Σ g {\displaystyle \Sigma _{g}} is a 4 n {\displaystyle 4n} -gon which gives Σ g {\displaystyle \Sigma _{g}} a CW-structure with one 2-cell, 2 n {\displaystyle 2n} 1-cells, and one 0-cell.

7. Protein superfamily - Wikipedia

   en.wikipedia.org/wiki/Protein_superfamily

   Conversely, the individual families that make up a superfamily are defined on the basis of their sequence alignment, for example the C04 protease family within the PA clan. Nevertheless, sequence similarity is the most commonly used form of evidence to infer relatedness, since the number of known sequences vastly outnumbers the number of known ...

   By then, Saundrah had moved to Europe, and we were in Seattle, so we figured our kids' time together would be limited. We also thought the shared name would be a nice bond between our two children ...

9. Comparative anatomy - Wikipedia

   en.wikipedia.org/wiki/Comparative_anatomy

   An example of a 20th-century comparative anatomist is Victor Negus, who worked on the structure and evolution of the larynx. Until the advent of genetic techniques like DNA sequencing , comparative anatomy together with embryology were the primary tools for understanding phylogeny , as exemplified by the work of Alfred Romer .
