Which are the major components of ribosomes?
Ribosomes are composed of two subunits: a large subunit and a small subunit. These subunits are made up of ribosomal RNA (rRNA) and proteins. The rRNA plays a crucial role in catalyzing protein synthesis, while the proteins help stabilize the structure of the ribosome.
What is the final step of translational initiation in both bacteria and eukaryotes?
union of the large subunit with the small subunit to form the intact ribosome
What is the structure that synthesizes proteins in bacteria?
The structure that synthesizes proteins in bacteria is called a ribosome. Ribosomes are responsible for translating the genetic information from messenger RNA (mRNA) into specific amino acid sequences that make up proteins. In bacteria, ribosomes are composed of a small subunit and a large subunit that work together during protein synthesis.
What is the subunit of a ribosome holds onto the mRNA strand?
The ribosomal subunit of a ribosome holds onto the mRNA strand
What are the physical properties of proteases?
Proteases are enzymes that break down proteins. They are typically soluble in water and have an optimal pH range for activity. Proteases can vary in size and structure, ranging from small single-chain enzymes to large multi-subunit complexes.

Ribosomes are made up of two subunits?
There are two components.They are rRNA and proteins
What are the chemical components of ribosomes are proteins?
Ribosomes are primarily composed of RNA and proteins. The RNA component is responsible for the catalytic activity of ribosomes in protein synthesis, while the proteins provide structural support and aid in the overall function of the ribosome.
What do ribosomes look Ike?
Ribosomes structures vary. Some however have a large subunit on the top and a small subunit on the bottom
What is the final step of translational initiation in both bacteria and eukaryotes?
union of the large subunit with the small subunit to form the intact ribosome
What are the major components of a ribosome?
A ribosome is composed of two subunits, a large subunit and a small subunit, made up of a combination of ribosomal RNA (rRNA) and protein molecules. The large subunit is responsible for peptide bond formation during protein synthesis, while the small subunit helps in mRNA recognition and initiation of protein synthesis.
What is the structure that synthesizes proteins in bacteria?
The structure that synthesizes proteins in bacteria is called a ribosome. Ribosomes are responsible for translating the genetic information from messenger RNA (mRNA) into specific amino acid sequences that make up proteins. In bacteria, ribosomes are composed of a small subunit and a large subunit that work together during protein synthesis.
What correctly identifies the ribsomes within the prokaryotic cell?
Ribosomes in prokaryotic cells are identified as small and numerous granules present in the cytoplasm. They are responsible for protein synthesis by translating messenger RNA into proteins. Prokaryotic ribosomes are comprised of a small 30S subunit and a large 50S subunit, with a total size of 70S.
Why are ribosomes smaller in prokaryotes?
Ribosomes are smaller in prokaryotes because they have different sizes and structures compared to eukaryotic ribosomes. Prokaryotic ribosomes (70S) consist of a small 30S subunit and a large 50S subunit, while eukaryotic ribosomes (80S) have a small 40S subunit and a large 60S subunit. Additionally, the smaller size of prokaryotic ribosomes allows them to be more efficient in protein synthesis.
How does the structure of the 60s ribosome contribute to its function in protein synthesis?
The structure of the 60s ribosome, made up of a large and small subunit, plays a crucial role in protein synthesis. The large subunit helps to bind transfer RNA (tRNA) molecules carrying amino acids, while the small subunit helps to locate the start codon on messenger RNA (mRNA). This allows the ribosome to bring together the tRNA molecules and mRNA to facilitate the formation of new proteins.
Are eukaryotic ribsomes composed of 60S and 40S subunits?
Yes, eukaryotic ribosomes are composed of a large 60S subunit and a small 40S subunit that come together to form the functional 80S ribosome. These subunits are made up of both RNA and protein components, with the 60S subunit containing 3 types of rRNA molecules and over 49 proteins, while the 40S subunit contains 1 type of rRNA and around 33 proteins.
What is the subunit of a ribosome holds onto the mRNA strand?
The ribosomal subunit of a ribosome holds onto the mRNA strand
