Yes; the small intestine has carrier proteins for transport, as do all other cellular structures.
Yes, proteins are made in small structures called ribosomes. Ribosomes can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum, where they translate messenger RNA (mRNA) into amino acid chains, forming proteins. These structures play a crucial role in the process of protein synthesis, essential for cellular functions and overall organismal health.

The ribosome translates the mRNA into protein.
ribosomes
DNA is the genetic information in an individual it is coiled into small ball like structures called histones histones are coiled into small structures called nucleosomes the nucleosomes are then coiled into chromatin, which is our chromosomes
Ribosomes have a small granular structure and are responsible for protein synthesis in cells. They are made of RNA and proteins and can be found in the cytoplasm or attached to the endoplasmic reticulum.
The right question would be, "Do cells make proteins FROM small structures called amino acids?" The short answer is, yes. If your interested in how look up the Hierarchy of Protein Structures. Specifically: Primary Structure ie. the amino acid sequence Secondary Structure ie repeating folding patterns (which help determine function.) Tertiary Structure ie. many folds and patters create a 3-D shape. For some proteins this is the final structure to a functional protein (such as ribonuclease). Quaternary Structure ie. Most functional proteins are comprised of two or more polypeptides that each adopt a Tertiary Structure (see above) and then assemble with each other. When proteins consist of more than one polypeptide chain, they are said to have Quarternary Structure.
the tiny structures within the small intestine that absorb nutrients are called Villi
