Answer:
A major transcription factor is inactivated or an oncogene is overexpressed
Explanation:
A microarray is a technique widely used in molecular biology for the detection of the expression of target genes. A microarray is composed of microscopic spots that contain DNA probes which hybridize with the target acid nucleic (generally an mRNA). The hybridization of probe-target produces fluorescence or chemiluminescence, thereby it is possible to detect gene expression in the sample. The inactivation of major transcription factors (e.g., p53) or overexpression of oncogenes (e.g., c-Myc) are well-known to produce aberrant gene expression patterns as observed in this case.
Answer:
In biomass pyramid living matter is present at all the trophic level in the ecosystem.
Explanation:
There are three ecological pyramids that are the pyramid of biomass, the pyramid of energy, and the pyramid of numbers.
Pyramids of biomass represent the total living matter present at each of the trophic levels in the ecosystem. It shows how much biomass of lower trophic levels is required to support the biomass of successive trophic levels.
The pyramid of biomass can be straight or inverted. In straight pyramid, larger biomass of lower trophic level supports smaller biomass of upper trophic level and vice-versa occurs with an inverted biomass pyramid. The pyramid of the number shows the number of the organism at each trophic level.
