Proteins are the macromolecules coded in our DNA that function as a biocatalyst and build our body. Apart from Biological knowledge, there are spectacular concepts in the field of proteins. How does a protein produce a function, how do they interact, how did they evolve and how do protein mutations cause disease.
Protein is necessary for the building and repair of body tissues.It produces enzymes, hormones, and other substances the body uses.It regulates body processes, such as water balancing, transporting nutrients, and making muscles contract.Protein keeps the body healthy by resisting some diseases commo…

Proteins are macromolecules that are made and used by all living things, relatively big molecules (polymers) that consist of smaller building blocks (monomers) called amino acids. Each amino acid is a chemical composed of carbon, nitrogen, hydrogen, and oxygen and some of them have other elements li…

Basically, a meat substitute like Quorn or Tofu. It gives a lot of protein like real meat does, so it's a healthy substitute for meat. Vegetarians find it useful, but it is healthier than meat so can actually be considered a much better option. It's primary function is to taste like meat and give th…

Most, but not all Prior to 1967, the assumption was that all biological catalysts were proteins. But an investigation into RNA splicing showed that there was no protein involved in cutting introns out of hnRNA (pre-RNA). In fact, the molecule responsible for breaking the phosphodiester bonds was snR…

Proteins serve in two major roles. Some of them make up part of the structure of our bodies. Others are enzymes. An enzyme is a protein that works like a tool. It helps a particular chemical reaction take place.Protein helps in building and repairing the body tissues. it also produces enzymes and ho…

The process of making a protein is called "Protein Synthesis." This involves a strand of mRNA making an exact opposite of one strand of DNA, then bringing it to the ribosome where tRNA's help bring in amino acids. When a stop codon is reached, the amino acid chain stops and is called a protein.

Proteins actually start off as DNA. One strand of our double stranded DNA (chromatin) is copied by enzymes and taken to the ribosomes. At the ribosomes 3 bases of the strand of what is now called RNA code for one of 20 different Amino Acids (the building blocks of protein). When the strand is fully …
