Front

What is mRNA and its function in the cell?

Back

mRNA (messenger RNA) is a type of RNA that carries genetic instructions from DNA in the nucleus to the ribosomes for protein synthesis.

Front

What are the primary functions of epithelial tissue?

Back

Epithelial tissue serves as a protective barrier, facilitates absorption, secretion, and sensation.

Front

What is the role of muscle tissue in the body?

Back

Muscle tissue is responsible for movement, maintaining posture, and producing heat.

Front

What is the function of nervous tissue?
