In the study of genetics, alleles are different forms of a gene. If a gene has two alleles, A and a, and the frequency of allele A is 0.6, what is the frequency of allele a? A. 0.2 B. 0.4 C. 0.6 D. 0.8 相关知识点:
Considering the central role that genes play in the understanding of biology, it is surprising that no single, simple definition of a gene exists. This is partly because genes are under multiple evolutionary constraints, and partly because the concept of a gene has both structural and functional ...
Pop music is the name for different forms of popular, commercial (商业) music. It had its beginning in the USA and spread throughout the whole world during the 1950s and 1960s. It is widely liked by the young people. The best known early form of pop music was “rock’ n’ roll”;...

The dent in the end of each kernel forms during the drying process, when the soft starch in the center shrinks more than a layer of hard starch around the sides. Since dent corn and other field corns take some processing to eat, most folks who grow them want to plant a larger amount ...
However, it remains to be further clarified in next experiments about how the members of GTPase are organized together and what the exactly mechanisms are for autophagosome formation in alternative autophagy. After autophasome formation, UV radiation resistance associated gene (UVRAG) and the PtdIns3K...
What is an alteration in the DNA structure or sequence of a gene called? What is DNA composed of? What is the strand of DNA that is not transcribed called? What process do cells use to make copies of their DNA? The process by which DNA is copied to be passed on ...
“splitters” and pathologists using very strict or more liberal diagnostic criteria. We now need to move beyond disciplinary boundaries to make progress. PD should be considered a syndromic spectrum of many different primary conditions. We know this because rare inheritable forms of Parkinsonism are ...
