The answer is aneuploidy.
This means having an abnormal number of chromosomes
in a cell. MAD protein ensures that the spindle fibers
during metaphase of mitosis, attach properly.
The MAD protein inhibits progression to anaphase if this
process of spindle attachment is defective.
Answer:
Habitat is a place in which organisms live, and niche is the way in which an organism fits into its habitat
Answer:
Explanation:
Energy in _SUNLIGHT__ is absorbed by an electron in a photocenter. This energy is converted from light energy into chemical energy into kinetic energy as the energized electron is used in back to back REDOX reaction in the electron transport chain, ETC. The ETC creates _AN ENERGY GRADIENT__ which is used by the cell to power the formation of ATP. In _CYCLIC PHOSPHORYLATION__ (cyclic or noncylcic) the electron returns to the photocenter. In _NON-CYCLIC PHOSPHORYLATION__ (cyclic or non-cyclic), the electron reduces NADP+ to form _NADPH__.
Photophosporylation is the process of using light (photo) to produce ATP from ADP (phosphorylation i.e. addition of phosphorous). There are two types: cyclic and non-cyclic phosphorylation.
In non-cyclic phosphorylation, there are two photosystems (photocenter) involved, and electron is passed to NADP+.
In cyclic phosphorylation, one photosystem is involved and the electron is not transferred to NADP+, it is circled back to the photosytem.
The reduced form of NADP+ is NADPH. (Remember that: reduction is defined as the addition of hydrogen)
<span>Before the completion of the Human Genome Project, it took few years before the well-known forecasts stated that humans had at least 100,000 genes. But latest Human Genome Project evaluates lowered number to a more timid range of 20,000 to 25,000. It has helped to narrow the range of feasible genes and to separate certain candidates as supplying to particular diseases. Scientists have also re-evaluated past conclusions, such as the idea that genes are self-restrained, detached pieces of DNA with defined character. They now know that some genes that tasks simultaneously can make more than one protein; where in fact the average gene might make three proteins. Also, genes will be visible to grab genetic code from other DNA parts</span>
