essential gene उदाहरण वाक्य

Because the male specific region is very small and contains no essential genes, it is even possible to artificially induce XX males and YY females to no ill effect
To generate mutants of essential genes, the CORE cassette can be inserted downstream of the gene of interest, however this limits the regions of the gene available for mutation.
Frequent Seattle visitor John Sayles once said that he believed the Seattle character had some essential gene that loves movies " the way Brooklyn used to love baseball ."
When the colony is grown under ultraviolet light, say, the yeast strains that lack an essential gene for surviving ultraviolet light will show as absent from the chip's roll call.
During the 1990s, Ohsumi's group described the morphology of autophagy in yeast, and performed mutational screening on yeast cells that identified essential genes for cells to be capable of autophagy.

As a result, due to the prevalence of cytosine to thymine conversions, the most common SNP, would cause a gradual separation between the few essential genes within variable gene deserts.
Although the number is more difficult to measure in higher eukaryotes, mice and humans are estimated to have around 2000 essential genes ( ~ 10 % of their genes ).
Cells cannot function if DNA damage corrupts the integrity and accessibility of essential information in the genome ( but cells remain superficially functional when non-essential genes are missing or damaged ).
Essential genes include Housekeeping genes ( critical for basic cell functions ) as well as genes that are expressed at different times in the organisms constitutively expressed at a relatively constant level.
Now that they have synthetic cells growing in their laboratory, the JCVI group can focus on their ultimate goal of synthesizing a minimal cell containing just the essential genes necessary for life.
