∙
Mitotic cell division starts with the condensing of chromosome accompanied by splitting of the centrosome and its movement towards the opposite poles.
∙
As the nuclear envelope and nucleolus disappear, spindle fibres arise from the centrosomes and start binding to the condensed chromosomes at the centromeres.
∙
The chromosomes bound by the spindle fibers are then arranged in the middle of the cell forming the equatorial metaphase plate.
∙
Next the centromere splits and the sister chromatids are pulled away towards the poles by the contraction of spindle fibres.
∙
Following this, a cleavage furrow starts to develop in the middle of the cell while the nuclear membrane starts to reappear around the separated chromatids.
∙
The condensed chromatids start thinning into chromatin fibre along with reappearance of the nucleolus and the cleavage furrow deepening further.
∙
Finally as the nuclear membrane becomes fully intact, the cleavage furrow deepens and split the cells from middle into two daughter cells.
A Comparing the composition of the crust to other bodies on the solar system
Answer:
The correct answer is option B) "a deletion of two nucleotides".
Explanation:
A frameshift mutation is a type of genetic modification caused by the insertion or deletion of one or more nucleotides in a position that results in changing the sequence at which codons are translated in the ribosome. Frameshift mutations have the most serious effect on the polypeptide products since it results in changing completely the sequence of the protein. A deletion of two nucleotides after the AUG start of translation would result in a frameshift mutation, therefore this mutation would have the most serious effect on the polypeptide product.
