Ribosomes in a eukaryotic cell
WebbIn eukaryotes, cytoplasm specifically means the region outside the nucleus but inside the plasma membrane. DNA is the genetic material of the cell. Ribosomes are molecular machines that synthesize proteins. Despite these similarities, prokaryotes and eukaryotes differ in a number of important ways. Webb18 dec. 2016 · Like eukaryotic cells, prokaryotic cells have cytoplasm, a gel-like substance that makes up the “filling” of the cell, and a cytoskeleton that holds components of the cell in place. Both prokaryotic cells and eukaryotic cells have ribosomes, which are organelles that produce proteins, and vacuoles, small spaces in cells that store nutrients and help …

Did you know?
Webb8 juni 2024 · Ribosomes, large complexes of protein and ribonucleic acid (RNA), are the cellular organelles responsible for protein synthesis. They receive their “orders” for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA (mRNA). Ribosomes are compositionally heterogeneous between species and even within the same cell, as evidenced by the existence of cytoplasmic and mitochondria ribosomes within the same eukaryotic cells. Certain researchers have suggested that heterogeneity in the composition of ribosomal proteins in mammals is important for gene regulation, i.e., the specialized ribosome hypothesis. However, this hypothesis is controversial and the topic of ongoing research.
