1. What is the rough endoplasmic reticulum?

  • studded with ribosomes, segregates newly synthesized plasmids and transports them to other areas, chemically modifies proteins
  • studded with ribosomes, segregates newly synthesized proteins and transports them to other areas, chemically modifies proteins
  • studded with cytoplasm, segregates newly synthesized proteins and transports them to other areas, chemically modifies proteins
  • studded with ribosomes, segregates newly synthesized proteins and transports them to other areas, cannot chemically modify proteins
