Which of the following is/are possible site(s) of protein synthesis in a typical eukaryotic cell?

What organelle is the site of protein synthesis in eukaryotic cells?

Eukaryotic cells have a true nucleus , which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes , the cellular organelles responsible for protein synthesis.

Where would you find a protein in a eukaryotic cell?

Ribosomes are found in many places around a eukaryotic cell . You might find them floating in the cytosol. Those floating ribosomes make proteins that will be used inside of the cell . Other ribosomes are found on the endoplasmic reticulum.

In which of the following sites might protein synthesis occur?

In which of the following sites might protein synthesis occur in a typical eukaryotic cell? – Proteins can be synthesized on bound ribosomes on the rough ER, but this is not the only place in the cell where protein synthesis occurs .

What are the 3 common parts of a typical eukaryotic cell?

Solution : Plasma membrane , nucleus and cytoplasm .

Which organelle is responsible for protein synthesis?

The endoplasmic reticulum (ER) is a membranous organelle that shares part of its membrane with that of the nucleus . Some portions of the ER, known as the rough ER , are studded with ribosomes and are involved with protein manufacture.

What is the cell structure which is the site of protein synthesis?

Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes , and the exact number depends on how active a particular cell is in synthesizing proteins.

What transports proteins in a cell?

The Golgi apparatus transports and modifies proteins in eukaryotic cells . The Golgi apparatus is the central organelle mediating protein and lipid transport within the eukaryotic cell .

What is the first step in protein synthesis called?

The first step of protein synthesis is called Transcription. It occurs in the nucleus. During transcription, mRNA transcribes (copies) DNA. DNA is “unzipped” and the mRNA strand copies a strand of DNA. mRNA will then attach itself to a ribosome.

What is the first step in protein synthesis in eukaryotic cells?

STEP 1: The first step in protein synthesis is the transcription of mRNA from a DNA gene in the nucleus. At some other prior time, the various other types of RNA have been synthesized using the appropriate DNA. The RNAs migrate from the nucleus into the cytoplasm.

What is correct for protein synthesis?

Protein synthesis is the process in which cells make proteins . It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.

Which two cells structures work together in the process of protein synthesis?

The two cell structures that are involved in protein synthesis are the ribosome and the endoplasmic reticulum.

What is the function of protein synthesis?

Protein synthesis represents the major route of disposal of amino acids . Amino acids are activated by binding to specific molecules of transfer RNA and assembled by ribosomes into a sequence that has been specified by messenger RNA, which in turn has been transcribed from the DNA template.

What are 4 examples of eukaryotic cells?

Examples of Eukaryotic Cells: Animals such as cats and dogs have eukaryotic cells. Plants such as apple trees have eukaryotic cells. Fungi such as mushrooms have eukaryotic cells. Protists such as amoeba and paramecium have eukaryotic cells. Insects have eukaryotic cells.

What is the most important part of a eukaryotic?

The nucleus is particularly important among eukaryotic organelles because it is the location of a cell’s DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.

What are the key differences between prokaryotic and eukaryotic cells?

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
