Explanation:
Transgenic organisms can be described as organisms which have a foreign gene inserted into their genome. Transgenic organisms are of huge economic importance and are emerging to provide benefit for humans and the Earth.
The transgenic organisms are being used as a replacement for fuel which will benefit the humans and the Earth.
Transgenic organisms have evolved and made strong roots in the field if medicine in today's world.
Transgenic plants are being used to produce crops which are resistant to pests and hence are of huge economical importance.
Answer:
S Phase
Explanation:
The synthesis phase of interphase takes the longest because of the complexity of the genetic material being duplicated. Throughout interphase, nuclear DNA remains in a semi-condensed chromatin configuration. In the S phase, DNA replication results in the formation of identical pairs of DNA molecules, sister chromatids, that are firmly attached to the centromeric region. The centrosome is duplicated during the S phase. The two centrosomes will give rise to the mitotic spindle, the apparatus that orchestrates the movement of chromosomes during mitosis. At the center of each animal cell, the centrosomes of animal cells are associated with a pair of rod-like objects, the centrioles, which are at right angles to each other. Centrioles help organize cell division. Centrioles are not present in the centrosomes of other eukaryotic species, such as plants and most fungi.
