Explain the function of ribosomes

Answer 1

rRNA is a massive molecule consisting of two parts; a small section, and a large section. It is between these two sections that the mRNA fits, and into the large selection that the tRNA complexes (with attached amino acids) are taken. rRNA molecules have two main binding sites. When a tRNA molecule is bound, the mRNA molecule moves along one space, and another tRNA molecule binds. When this happens, the amino acids at the ends of the tRNA molecules are very close together, and a peptide bond forms. The mRNA then moves along again and the first tRNA molecule breaks away. This is translation

Answer 2

Ribosomes are the components of cells that aid in protein synthesis - composing polypeptides from amino acids.
There is one main function of Ribosome. The main function is mRNA translation.

Answer 3

It binds to mRNA and assembles protein using tRNA complex.

They are also the sites responsible for protein synthesis. It's been described as a kind of platform or workbench where proteins are built. They use the RNA copy of a gene to read it like a blueprint to construct the protein needed.

A ribosome is either free (like on the cytoplasm) or on rough endoplasmic reticulum. They are also the smallest organelle.

Answer 4

Ribosomes translate the instructions on messenger RNAto protein by means of transfer RNA/amino acid complexes.

1. A messenger RNA molecule binds to the active site of a ribosome.
2. A transfer RNA/amino acid complex attaches to a matching nucleotide triplet on the messenger RNA at the active site.
3. The ribosome catalyses binding of the amino acid into a protein molecule then separates the amino acid from the transfer RNA that had carried it.
4. The ribosome ejects the free transfer RNA and advances the messenger RNA at the active site by three nucleotides.
5. Repeat at step 2; unless the nucleotide triplet at the active site is a stop code, then detach the finished protein molecule.

Answer 5

Ribosomes synthesize proteins. They take strands of different strands of RNA ( transferRNA [tRNA] and messengerRNA [mRNA] ) and concatenate amino acids from the tRNA together to form a long strand of protein.

Answer 6

The primary function of Ribosomes is to read and translate the cell's genetic code, then reproduce (replicate) the proteins that the code represents.

Without the ribosomes this coded message could not be read or replicated. Without this replication, the cells would simply age and die, and the organism would die with them.

They do this by translating messenger RNA (mRNA) into proteins. Messenger RNA is simply a copy of the DNA from the nucleus that is allowed to enter the cytoplasm and be used to make proteins.

Ribosomes are the sites of protein synthesis, where RNA is translated into protein. When cells need large numbers of proteins, they must first build numerous ribosomes. Because protein synthesis is so important to cells, there are large numbers of ribosomes in all cells, often numbering in the hundreds or thousands. For example, pancreatic cells and those of other glands have many ribosomes because they produce secretions that contain proteins.

In eukaryote cells, three of the four ribosomal RNA strands are synthesized in the nucleolus, a structure within the nucleus. The fourth ribosomal RNA strand is synthesized outside of the nucleolus and then transported into the nucleolus for ribosome assembly.

Ribosomal proteins enter the nucleolus and combine with the four waiting ribosomal RNA strands to create the large and small subunits each composed of two ribosomal structures. The two subunits unite outside the nucleus. Then the newly formed single unit begins to manufacture proteins.

Prokaryotic cells lack a nucleus or nucleolus so, in these cells, ribosomal synthesis takes place in the cytoplasm..

Ribosomes are bead like structures, usually found on the surface of the Endoplasmic Reticulum in eukaryotic cells, and are dispersed freely in some prokaryotic cells. Ribosomes are used in the synthesis of proteins and enzymes required by the cells for various purposes. Most of our cellular chemical reactions are enhanced (catalyzed) by enzymes, in order for the cells to function properly.

Ribosomes make proteins for use in the cell and for export.

a ribosome is a part of the cell in the animal

They make the amount of protein needed for the cell.

Answer 7

link amino acids together to form proteins

Answer 8

Ribosomes are involved in protein synthesis. They are like work stations in factories that read the directions and then assemble the proteins.

They involve in protein synthesis. They provide surface for it
