Which organelles found in both prokaryotic and eukaryotic cells make proteins?
The ribosome is found in both prokaryotic and eukaryotic cells. It is the site of protein synthesis (translation).
Which cell organelle is found in both eukaryotic and prokaryotic cells?
Ribosomes are found in both prokaryotic and eukaryotic cells.
What assembles proteins in prokaryotes?
An mRNA travels to the ribosome, which uses the information it contains to build a protein with a specific amino acid sequence. This process is called translation. Prokaryotes lack a nucleus, so their mRNAs are transcribed in the cytoplasm and can be translated by ribosomes immediately.
Which of the following would you find in both prokaryotes and eukaryotes?
Both prokaryote and eukaryote cells have a cell membrane. This is a lipid bilayer that keeps the contents of the cell in and keeps unwanted substances out. The membrane controls the movement of substances into and out of the cell. The material inside both types of cells is called the cytoplasm.
Which of the following structure is common to both prokaryotes and eukaryotes?
Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA.
What is found in prokaryotic and eukaryotic cells?
The cells of all prokaryotes and eukaryotes possess two basic features: a plasma membrane, also called a cell membrane, and cytoplasm. However, the cells of prokaryotes are simpler than those of eukaryotes. For example, prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus.
How prokaryotes and eukaryotes synthesize proteins?
In prokaryotes, mRNA molecules are polycistronic containing the coding sequence of several genes of a particular metabolic pathway. In eukaryotes, protein synthesis occurs in the cytoplasm. In prokaryotes, protein synthesis begins even before the transcription of mRNA molecule is completed.
What organelle is used to assemble proteins?
Proteins are assembled at organelles called ribosomes. When proteins are destined to be part of the cell membrane or exported from the cell, the ribosomes assembling them attach to the endoplasmic reticulum, giving it a rough appearance.
Do both prokaryotic and eukaryotic cells have Golgi apparatus?
Eukaryotic cells contain a membrane-bound nucleus and numerous membrane-enclosed organelles (e.g., mitochondria, lysosomes, Golgi apparatus) not found in prokaryotes.
Do both prokaryotes and eukaryotes have ribosomes?
All ribosomes (in both eukaryotic and prokaryotic cells) are made of two subunits — one larger and one smaller. In eukaryotes, these pieces are identified by scientists as the 60-S and 40-S subunits. In prokaryotes, the ribosomes are made of slightly smaller subunits, called 50-S and 30-S.
Is Golgi apparatus prokaryotic or eukaryotic?
The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus.
Which of these do all prokaryotes and eukaryotes share?
Prokaryotic cells are surrounded by a plasma membrane and have DNA, cytoplasm, and ribosomes, like eukaryotic cells. They also have cell walls and may have a cell capsule. Prokaryotes have a single large chromosome that is not surrounded by a nuclear membrane.
