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
What are the ribosomes linked togetherby a single strand of mRNA called?
Ribosomes linked together by a single strand of mRNA are called polysomes or polyribosomes. These structures allow multiple ribosomes to simultaneously translate the same mRNA molecule, increasing the efficiency of protein synthesis.
What attaches to the mRNA strand as translation begins?
After the two ribosomal subunits attach to a strand of mRNA, a tRNA molecule with the amino acid methionine attaches to the start codon, AUG.
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 Moves along the mRNA and helps form the peptide strand?
Ribosomes move along the mRNA during protein synthesis. They help bring together amino acids to form a peptide strand based on the nucleotide sequence of the mRNA.
How many strands does mRNA have?
mRNA typically consists of a single strand of nucleotides. It serves as a temporary copy of the genetic information in DNA and carries this information from the nucleus to the ribosomes for protein synthesis.
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 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 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.
Transcription is the process of what?
Transcription is the process of converting DNA into mRNA. During transcription, enzymes read the DNA sequence and create a complementary mRNA strand that carries the genetic information from the nucleus to the ribosomes for protein synthesis.
