Kutayuddha or kuta-yuddha (Sanskrit: कूटयुद्ध ISO: kūṭayuddha/ kūṭa-yuddha, also spelt Kootayudha) is a Sanskrit word made up of two roots: kuta (कूट) commonly explained as evil genius, crooked, devious, unjust or unrighteousness, and yuddha (युद्ध) meaning warfare.
An overlapping gene (or OLG) [1] [2] is a gene whose expressible nucleotide sequence partially overlaps with the expressible nucleotide sequence of another gene. [3] In this way, a nucleotide sequence may make a contribution to the function of one or more gene products.
DNA transposons, LTR retrotransposons, SINEs, and LINEs make up a majority of the human genome. Mobile genetic elements (MGEs), sometimes called selfish genetic elements, [1] are a type of genetic material that can move around within a genome, or that can be transferred from one species or replicon to another.
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
An inversion is a chromosome rearrangement in which a segment of a chromosome becomes inverted within its original position. An inversion occurs when a chromosome undergoes a two breaks within the chromosomal arm, and the segment between the two breaks inserts itself in the opposite direction in the same chromosome arm.
An open reading frame (ORF) is a reading frame that has the potential to be transcribed into RNA and translated into protein. It requires a continuous sequence of DNA which may include a start codon, through a subsequent region which has a length that is a multiple of 3 nucleotides, to a stop codon in the same reading frame.
The point of sperm entry defines the dorso-ventral axis - cells opposite the region of sperm entry will eventually form the dorsal portion of the body. [1] [3] In the frog Xenopus laevis, the animal pole is heavily pigmented while the vegetal pole remains unpigmented. [4]
Gene silencing is the regulation of gene expression in a cell to prevent the expression of a certain gene. [1] [2] Gene silencing can occur during either transcription or translation and is often used in research.
