Today we are going to learn what is the difference between hm rnas, sn rnas, m -i -r -ns, and s -i -r -ns, and s -n -o -r -nas.
00:15
So let's go over each of them.
00:19
So our heterogeneous nuclear rna refers to the large pre -m -r -r -nase of various nucleotide sequence.
00:30
That are made by rna polymerase 2 and precedes in the nucleus to become cytoplasmic rnas.
00:51
Also called precursors unprocessed mrna or pre -mrnas in the nucleus.
00:58
Now let's look at small nuclear rnas or snrnas.
01:03
They are a class of small rna molecules that are found within the splicing spectacles and cajole bodies of the cell nucleus and eukaryotic cells.
01:24
The average length of the sn rnas are approximately 150 nucleotides, and their functional role is processing.
01:37
The hn rnas in nipleus.
01:40
Now let's look at micrornas or mris, which is a small, single, stranded, non -coding rna found in plants, animals, and some viruses that functions in rna silencing and post -transcriptional regulation of gene expression.
02:05
They contain about 22 nucleotides and their functional role is the gut...
