These include the promoter region, a section of "upstream" DNA that binds RNA polymerase, the enzyme that forms the RNA copy. In Figure 1, an overly simplified version of a genetic message is presented. Other DNA segments called enhancers also regulate gene transcription, and these may be ...
What are the different forms of a gene called? They could be dominant or recessive.If there are 3 different alleles for a particular gene in a population of diploid organisms, how many different genotypes are possible in the population? a. 2 b. 12 c. 3 d. 9 e. 6...

The first step in plant speciation is the establishment of genotypic and phenotypic differences among populations, sometimes called plant races1. Although both neutral (i.e. genetic drift) and adaptive evolutionary processes can cause such variations, adaptation driven by selection is thought to be of...
What are different forms of the same gene called? a. factors b. alleles c. genes d. chromosomes e. chromatids What are the homologous and heterologous portions of the human sex chromosomes? What does the term diploid mean? A. Describes a ...

Many scientists believe that at one time the human body had the ability to make vitamin C, but due to a genetic mutation (in the L-gulonolactone oxidase gene), we lost this capacity over time. Essentially, all species of animals, including most mammals, can make vitamin C—the exceptions...
of major eukaryotic supergroups. Genes retained in the mitogenomes are depicted in purple, nucleus-encoded genes are in orange, and those lost or not detected are in white. Within each eukaryotic group, the species with identical gene distribution patterns were unified into one sector of a ...
Embryonic stem cells (ESCs) can be maintained in the naïve state through inhibition of Mek1/2 and Gsk3 (2i). A relevant effect of 2i is the inhibition of Cdk8/19, which are negative regulators of the Mediator complex, responsible for the activity of enhancers. Inhibition of Cdk8/19...
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 ...
