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".
[1] [2] The term covers the organism's morphology (physical form and structure), its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior. [ citation needed ] An organism's phenotype results from two basic factors: the expression of an organism's genetic code (its genotype ) and the ...
AP-1 was first discovered as a TPA-activated transcription factor that bound to a cis-regulatory element of the human metallothionein IIa promoter and SV40. [3] The AP-1 binding site was identified as the 12-O-Tetradecanoylphorbol-13-acetate response element (TRE) with the consensus sequence 5’-TGA G/C TCA-3’. [4]
How to use a microarray for genotyping. The video shows the process of extracting genotypes from a human spit sample using microarrays. Genotyping is a major use of DNA microarrays, but with some modifications they can also be used for other purposes such as measurement of gene expression and epigenetic markers.
Spot analysis, spot test analysis, or spot test is a chemical test, a simple and efficient technique where analytic assays are executed in only one, or a few drops, of a chemical solution, preferably in a great piece of filter paper, without using any sophisticated instrumentation.
During embryonic development, AP-2 alpha is expressed in neural crest cells migrating from the cranial neural folds during neural tube closure, and is also expressed in ectoderm, parts of the central nervous system, limb buds, and mesonephric system suggesting that AP-2 alpha plays an important role in the determination and development of these ...
A program executive officer, or PEO, is one of a few key individuals in the United States military acquisition process.As can be seen from the examples below, a program executive officer may be responsible for a specific program (e.g., the Joint Strike Fighter), or for an entire portfolio of similar programs (e.g., the Navy PEO for aircraft carriers).
Normally, the sound of the patient's voice becomes less distinct as the auscultation moves peripherally; bronchophony is the phenomenon of the patient's voice remaining loud at the periphery of the lungs or sounding louder than usual over a distinct area of consolidation, such as in pneumonia.
