What does “intron” stand for?

Introns stands for intervening sequences within a gene.

Explanation:

Introns are the nucleotide sequences within a gene which are intervening but noncoding regions on an RNA transcript which is spliced before the RNA translation to protein

Introns do not code amino acids for protein synthesis. They break the gene sequence in the DNA strand.

The introns form a large chunk and interfere with the protein coding of exons, hence are removed by splicesomes through splicing at the splice junctions.

Improper splicing of introns lead to faulty protein formation

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
