Answer:
The gene of interest from another source.
Explanation:
A plasmid is a small, circular double-stranded extrachromosomal DNA molecule within a cell particularly a bacteria cell that is physically separated from chromosomal DNA and can also replicate independently.
Expression vector is usually a plasmid (or a virus can also be utilized) constructed to allow for gene expression in cells. The vector is used to introduce a gene of interest into a target cell, and can drive the cell's mechanism for protein synthesis to produce the protein encoded by the gene, thus giving rise to the expression of the gene.
This gene of interest is integrated into the plasmid that is cut by endonucleases and then ligated using DNA ligase. Thus the expression differs from the normal plasmid in that it contains an external gene sequence.
Sure! The metaphase stage in the cel is the third step in mitosis. The chromosomes line up in the middle of the cell due to the fact that the spindle fibers pull them towards the middle (the chromosomes are in a single file line). In addition, the spindle fibers connect to the centromeres. Hope this helps :)
Answer:
The first astronauts to land on the moon observed the existence of thin layers of dust hovering above the lunar surface. Like there is no wind on the moon, it was understood that this phenomenon was linked to the photoelectric effect caused by sunlight: electrons are extracted from the
grain of dust from lunar soil when receiving energy electromagnetic radiation from the sun and, thus the grains become positively
loaded.
The same process also starts electrons of the lunar surface, contributing to the positive charge on the illuminated side of the Thus, the electric field generated by the surface of the moon makes the charged grains of sand suffer electrical force upward by balancing your weight
Explanation:
Dust can be formed by small particles, smaller than 500 micrometers, but the nature can be so different from one place to another.
Mass extinctions. Dinosaurs is the most recent (?)
