What do ribosomes attract?
ribosomes is where protein is synthesised so i suppose they attract mrna for the code to make the protein and the amino acid to build the protein. ribosomes is where protein is synthesised so i suppose they attract mrna for the code to make the protein and the amino acid to build the protein.
What are proteins produced by?
Proteins are produced by the ribosomes which link together amino acids, the building blocks of proteins, via peptide bonds based on the instructions given by the mRNA (messenger RNA) strand it is translating. The ribosomes link together amino acids like beads on a string. This string of beads is a protein.
What does ribosomes do in a bacteria cell?
A bacterial cell contains about 10,000 ribosomes which co up to 30% of the weight of the bacterium. In contrast to most eukaryote ribosomes, the bacterial ribosomes do not appear to be attached to internal cell membranes, but are found free in the cytoplasm. In functionally, active bacteria the cytoplasm is packed -with free and randomly distributed ribosomes. This dense packing may mask any attachment to internal membranes. Strings of ribosomes have been found loosely attached to the inside of the plasma membrane.
What does mRnA tRnA and rRnA stand for and what do they do?
DNA is found in the nucleus of a eukaryotic cell as condensed chromatin fibres wrapped around histone proteins in the form of chromosomes. Mitchondria have their own DNA, mitochondrial DNA, which is found in the mitochondria. There are different types of RNA, ribosomal RNA, messenger RNA and transfer RNA. Ribosomal RNA (rRNA) is found in ribosomes and in the nucleolus where it is manufactured. messenger RNA (mRNA) can be found in the nucleus when it is translating DNA to mRNA in translation. It can also be found in the cytoplasm or attached to ribosomes that are transcribing the mRNA to synthesise polypeptides/protiens. transfer RNA (tRNA) can be found in the cytoplasm or around ribosomes where they transfer amino acids to the ribosome for protein synthesis in transcription.
Where does polyadenylation occur?
Polyadenylation occurs at the 3' end (the back) of an mRNA strand in the nucleus of the cell. This act of polyadenylation creates a polyadenine (polyA) tail. mRNA cannot leave the nucleus of the cell unless polyadenylation occurs. PolyA tails seem to protect integrity of the mRNA molecule, which is exposed to multiple proteins that can degrade it once shipped to the cytoplasm
Do mRNA carry information from the RNA to the ribosomes?
Yes. The ribosome moves along the mRNA not the other way around as some say.
What are the ribosomes linked togetherby a single strand of mRNA called?
polysomes or polyribosomes
Where is protein made?
Proteins are made in the ribosomes when the mRNA strand from the nucleus is matched with the anti codon tRNA strand.
What happens to the original DNA strand once the mRNA is completely copied?
mRNA goes to the ribosomes for translation.
What is larger vesicles or ribosomes?
No, ribosomes are not bigger than chloroplasts.
What subcellular structure is involved in translation?
In translation (RNA to Protein) a ribosome attaches to an mRNA strand and uses the mRNA to create a protein. There are other types of RNA and protein that can modify the mRNA strand but ribosomes are the main structure involved in translation.
What is the term for a group of ribosomes on one mRNA chain?
Polysome.
A cellular process that is accomplished by a ribosomes?
Protein synthesis is a cellular process that is accomplished by ribosomes. Ribosomes are responsible for translating the genetic information encoded in mRNA into a specific sequence of amino acids, which form proteins. They do this by reading the mRNA and aligning the correct amino acids according to the codons on the mRNA strand.
What are ribosome and free ribosomes and what do they do in animal cells?
Ribosomes assemble proteins from an mRNA sequence. They are either free ribosomes in the cytoplasm or bound to the endoplasmic reticulum in what is called the Rough ER.
How does mRNA get the code for gene from DNA?
mRNA is basically instructions for the creation of a protein. (the m stands for messenger) proteins are made in the ribosomes and they are made from 'amino acids' and basically these mRNA's tell the amino acids how to align to make a specific protein.
Why are some ribosomes located on rough ER?
mRNA binds to the ribosomes on the rough endoplasmic reticulum in order to form proteins. tRNA collects and binds amino acids according to the arrangement of nitrogenous bases in mRNA bound to the ribosomes on the RER. Without the ribosomes, mRNA wouldn't be able to bind to the RER and the translation stage of protein synthesis wouldn't be able to occur.
Where are ployribosomes found?
Polyribosomes (or polysomes) also known as ergosomes are a cluster of ribosomes, bound to a mRNA molecule.Polyribosomes read one strand of mRNA simultaneously, helping to synthesize the same protein at different spots on the mRNA, mRNA being the "messenger" in the process of protein synthesis. They may appear as clusters, linear arrays, or rosettes in routine: this is aided by the fact that mRNA is able to be twisted into a circular formation, creating a cycle of rapid ribosome recycling, and utilization of ribosomes. 5' 7-methylguanosine cap and 3' polyA tail aids in this process
