Mutations in the ribosomal protein gene RPS19 have been found to be associated with Diamond-Blackfan anemia (DBA), a rare syndrome that disrupts erythropoiesis, the process by which new red blood cells are produced. Which of the following provides the most likely explanation for the connection between a mutation in RPS19 and a disruption in erythropoiesis? A B с D The ribosomes in the cell are unable to package and transfer the components that are required for erythropoiesis. The ribosomes in the cell are unable to facilitate the movement of nutrients that are re- quired for erythropoiesis across the cell membrane. The ribosomes in the cell are unable to correctly synthesize the proteins that are re- sponsible for erythropoiesis. The ribosomes in the cell are unable to effectively produce the ATP that is required for

Proteins

We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.  

Protein Expression

The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
