prokaryotic cells do not have a nucleus.
I believe the miRNAs control gene expression by binding to mRNAs and degrading them or blocking their translation. The microRNAs are short non coding RNAs which function to regulate the process of gene expression. They bind to the 3-UTR of the target mRNAs and repress the production of protein by destabilizing the mRNA and translational silencing.
cellulose is a polysaccharide.
A significant class of biomolecules is polysaccharides. They are large chains of monosaccharide molecules that are linked together. These intricate biomacromolecules serve as a vital energy source for animal cells and are a crucial part of plant cells' structural makeup. The nature of the monosaccharides determines whether it is a homopolysaccharide or a heteropolysaccharide.
A branching polysaccharide is a type of carbohydrate that is different from a linear polysaccharide, which is a straight chain of monosaccharides.
Organisms have this energy in reserve. The molecules are hydrophobic because water cannot enter them because of the many hydrogen bonds present. They permit adjustments to the concentration gradient, which affects how the cells absorb nutrients and water.
