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.

How do some nucleotide sequences in DNA get copied into RNA when DNA and RNA have different bases. For example, how is the seque
kvasek [131]

Answer:

In RNA the base thymine is essencially replaced by the base uracil. So the sequence TGAC in DNA would get copied into RNA as ACUG.

Adenine pairs with uracil in RNA like it pairs with thymine in DNA
