Third generation sequencing technologies have the capability to produce substantially longer reads than second generation sequencing, also known as next-generation sequencing. [1] Such an advantage has critical implications for both genome science and the study of biology in general.
Advanced Placement (AP) Biology (also known as AP Bio) is an Advanced Placement biology course and exam offered by the College Board in the United States. For the 2012–2013 school year, the College Board unveiled a new curriculum with a greater focus on "scientific practices".
The inheritance of epigenetic marks in the immediate generation is referred to as intergenerational inheritance. [3] In male mice, the epigenetic signal is maintained through the F1 generation. [4] In female mice, the epigenetic signal is maintained through the F2 generation as a result of the exposure of the germline in the womb. [4]
An epigenetic clock is a biochemical test that can be used to measure age. The test is based on modifications that change over time and regulate how genes are expressed. Typically they can use DNA methylation levels, measuring the accumulation of methyl groups to one's DNA molecules, or more recently, based on the histone
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 ...
In biology, epigenesis (or, in contrast to preformationism, neoformationism) is the process by which plants, animals and fungi develop from a seed, spore or egg through a sequence of steps in which cells differentiate and organs form. [1] Aristotle first published the theory of epigenesis in his book On the Generation of Animals.
In biochemistry and molecular genetics, an AP site (apurinic/apyrimidinic site), also known as an abasic site, is a location in DNA (also in RNA but much less likely) that has neither a purine nor a pyrimidine base, either spontaneously or due to DNA damage. It has been estimated that under physiological conditions 10,000 apurinic sites and 500 ...
The second generation born in a country (i.e. "third generation" in the above definition) In the United States, among demographers and other social scientists, "second generation" refers to the U.S.-born children of foreign-born parents. [14] The term second-generation immigrant attracts criticism due to it being an oxymoron.
