Gene expression can occur at several points along the pathway from dna to rna to proteins. in one example of gene expression, the protein insulin must be trimmed to a smaller size. how is this is an example of gene expression? until the protein is trimmed, the ribosomes are not active. until the protein is trimmed, the shape of the dna blocks transcription. until the protein is trimmed, it is not useful to the cell. until the protein is trimmed, transcription is blocked by a repressor prote

Until the protein is trimmed it is not useful to the cell.

Absolutely sure!

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.
