How does the primary transcript in the nucleus of a prokaryotic cell compare to the functional mrna?

a) the primary transcript is larger than the mrna
b) the primary transcript is smaller than the mrna
c) the primary transcript and the mrna both contain introns
d) the primary transcript is the same size as the mrna

None of the answers is correct, because prokaryotic cell doesn't have nucleus

Explanation:

In eukaryotic cell, primary transcript is RNA synthesized via transcription in the nucleus. After processing it becomes mature mRNA. The processes of processining are addition of the 5' cap, 3'-polyadenylation, and alternative splicing (excision of introns). Because during the processing of RNA introns are removed the primary transcript is larger than the mRNA.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
