genetic engineering
Cloning.
We don't get any special proteins from microorganisms. What we get is vitamin K which is produced from a bacteria called E.coli and which lives in our intestine.
Golgi apparatus
Amino acids, carbohydrates, proteins, and other acids produced by the normal lactobacillus bacteria.
Proteins are labeled with radioactive amino acids so that they can be identified. Scientists use radioactivity to label proteins in order to track them during their experiments, you can follow protein degradation, label proteins that don't have antibodies, label all proteins produced at a certain time, separate proteins produced by intracellular pathogens from host proteins, among many other uses.
Human genes can be inserted into a bacteria and produce large numbers of human proteins on an industrial state!!
We study bacteria so that we can figure how fast they grow in different environments and temperatures and the different changes that the enzymes and proteins go through to be resistant to certain medication. . This helps scientists that study bacteria to figure out how to prevent that disease.
Proteins are produced by ribosomes on the surface of the rough endoplasmic reticulum.
Many bacteria reproduce in a process called Binary Fission. Where they replicate proteins such as ribosomes, as well as their DNA. Then they start to split, a septum is formed and eventually two cells are produced.
Proteins reflect DNA sequences, so scientists study proteins to look for genetic similarities and differences in organisms.
Antibodies produced by B-lymphocytes. Note that antibodies produced by T-lymphocytes stay attached to the cell that made them and do not circulate free in the blood. They are responsible for attacking whole cells and multicellular parasites.
If you're synthesizing the proteins yourself (meaning you didn't ingest them), then all proteins are produced by genes.
