A researcher claims that all living cells must be able to synthesize proteins in order to maintain homeostasis and perform basic
functions. What statement supports the scientist's claim? A) Ribosomes are required for protein synthesis, and all four cell types can synthesize proteins. B) Nuclei house the DNA, which is the blueprint for proteins. Cell types I, II, and III can synthesize proteins. C) Cell walls are required for cells to maintain their shape to manufacture proteins. Cell types II, III, and IV can synthesize proteins. D) Cells require lysosomes to digest cellular components to convert them into proteins. Only cell types I and III can synthesize proteins.
Answer: Option B) Nuclei house the DNA, which is the blueprint for proteins. Cell types I, II, and III can synthesize proteins.
Explanation:
All the genetic information that determines the traits expressed in an organism are loaded up within the DNA sequence. Hence, several genes that codes functional proteins are derived from the DNA, making DNA a blueprint for protein synthesis.
Thus, Cell types I, II, and III with DNA can synthesize proteins.
