Do RNA make polypeptides?

Translation involves a complex cellular organelle, the ribosome, which together with a number of accessory factors reads the code in a mRNA molecule and produces the appropriate polypeptide235. The ribosome is the site of polypeptide synthesis.

Do RNA make up proteins?

The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm. Through the processes of transcription and translation, information from genes is used to make proteins.

Does RNA only code for proteins?

Although non-coding DNA and RNA strands do not directly code for protein to be made, they often serve to regulate which genes are made into protein in many cases.

Does RNA catalyze the formation of peptide bonds?

In addition to proving that RNA is responsible for catalyzing peptide bond formation, these structures have provided important insights into the mechanistic details of how the ribosome functions.

Which RNA nuclear processing of eukaryotic pre mRNA?

When an RNA transcript is first made in a eukaryotic cell, it is considered a pre-mRNA and must be processed into a messenger RNA (mRNA).

How are proteins made from RNA?

Ribosomes make proteins using ribosomal RNA (rRNA). The ribosome reads the instructions found in the messenger RNA molecules in a cell and builds proteins from these mRNAs by chemically linking together amino acids (these are the building blocks of proteins) in the order defined by the mRNA.

How is a polypeptide chain synthesized in a eukaryotic cell?

In eukaryotic cells, transcription takes place in the nucleus . The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm , where translation occurs. During translation, the genetic code in mRNA is read and used to make a polypeptide.
