Proteins are widely used in cells to provide different functions such as providing structural support for cells or to act as enzymes to catalyze certain reactions. Since the beginning of evolution, cells have developed the ability to synthesize proteins. To manufacture proteins, cells follow a very systematic procedure that first transcribes DNA into mRNA and then translates the mRNA into chains of amino acids. The amino acid chain then folds into specific proteins. [11]
These two processes are
1. DNA Transcription
Protein synthesis initiates in the cell's nucleus when the gene encoding a protein is copied into RNA. Genes, in the form of DNA, are rooted in the cell's chromosomes. The process of transferring the gene's DNA into RNA is called transcription. Transcription helps to increase the amount of DNA by creating many copies of RNA that can act as the template for protein synthesis. The RNA copy of the gene is called the mRNA.
After transcription, the mRNA is transported out of the cell's nucleus through nuclear pores to go to the site of translation, the rough endoplasmic reticulum. [4]
2. RNA Translation
After the mRNA has been taken to the rough endoplasmic reticulum, it is fed into the ribosomal translation machineries. Ribosomes begin to read the mRNA sequence to convert the mRNA into protein. The mRNA sequence is matched three nucleotides at a time to a complementary set of three nucleotides in the anticodon region of the corresponding tRNA molecule....
As the essay declares proteins are widely used in cells to provide different functions such as providing structural support for cells or to act as enzymes to catalyze certain reactions. Since the beginning of evolution, cells have developed the ability to synthesize proteins. To manufacture proteins, cells follow a very systematic procedure that first transcribes DNA into mRNA and then translates the mRNA into chains of amino acids. The amino acid chain then folds into specific proteins.
According to the report findings protein synthesis initiates in the cell's nucleus when the gene encoding a protein is copied into RNA. Genes, in the form of DNA, are rooted in the cell's chromosomes. The process of transferring the gene's DNA into RNA is called transcription. Transcription helps to increase the amount of DNA by creating many copies of RNA that can act as the template for protein synthesis. The RNA copy of the gene is called the mRNA. After transcription, the mRNA is transported out of the cell's nucleus through nuclear pores to go to the site of translation, the rough endoplasmic reticulum.
