The sugar and phosphate portion of the nucleotides are found "<em><u>as segments of the rails</u></em>" on the DNA twisted ladder.
Scientists believe that amphibians evolved from bony fish. C.
in RNA Guanine(G) pairs with Cytosine(C) Adenine(A) pairs with Uracil(U) therefore in the anticodon we have to write the complementary letters
a.CGU
b.AAA
c.UGG
Guanine and adenine, structure-wise, are purines.
Answer:
1→4→5→3→2
∙
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.
