FAQ
Q: What is the role of proteins in the body?
A: Proteins are essential for building up the body, providing instructions, materials, and executing the work.
Q: How do broken bones heal?
A: Broken bones heal through a process that involves protein synthesis and the formation of new bone tissue.
Q: Explain the process of transcription.
A: Transcription is the process of copying DNA information into mRNA, providing a template for protein synthesis.
Q: What is the involvement of ribosomes in translation?
A: Ribosomes are key organelles that facilitate the translation process by reading the mRNA and aiding in protein formation.
Q: What is the function of tRNA in protein synthesis?
A: tRNA molecules carry specific amino acids to the ribosomes during translation, ensuring the correct sequence for protein formation.
Q: Describe how antibodies form when a person is sick.
A: Antibodies form as part of the immune response to combat pathogens, recognizing and binding to specific antigens to neutralize them.
Q: Explain how hair grows back.
A: Hair growth is stimulated by protein synthesis, as new cells are produced at the hair follicle and contribute to the lengthening of the hair shaft.
