Yes, ribosomes are composed of special proteins and nucleic acids. Each complete ribosome is constructed from two sub-units.
A eukaryotic ribosome is composed of nucleic acids and about 80 proteins and has a molecular mass of about 4,200,000 Da.
I'm answering this as 'What would happen to an animal that does not have ribosomes?' Ribosomes are the main site for DNA translation, where the genetic code (held in DNA) is translated into a sequence of amino acids. Three 'bases' or segments in the DNA molecule code for one amino acid. The amino acids then join together to form proteins, the building blocks of life. Therefore, if there were no ribosomes, no proteins would be produced and, therefore, the animal would quickly die. I'm not sure if there are any animals which do not have ribosomes, and have worked out another way to synthesise DNA...
ribosomal RNA (or rRNA) is a part of the ribosomes usually found on the Endoplasmic Reticulum. Hope this helps! rRNA helps build the proteins. It decodes mRNA into amino acids and provides peptide bonds for amino acids.
Ribosomes
transcription and translation
Ribosomes are mini cellular structures that are responsible for protein synthesis in cells. They help translate the genetic information from the cell's DNA into functional proteins that carry out various functions in the body.
DNA tells a ribosome how to assemble a protein.
RNA is the main protein synthesis DNA nucleotides ribosomes. This is part of the body.
Involved in protein synthesis within a cell. Ribosomes are the site of protein synthesis, mRNA carries the genetic information from the DNA to the ribosomes, and tRNA brings the amino acids to the ribosomes for protein assembly.
Yes they can produce. They have DNA and ribosomes
DNA creates messanger RNA by transcription and this mRNA reaches the site of protein synthesis. The message of type of protein to be synthsized is received by ribosomes from RNA and the ribosomes make protein from amino acids present in the cytoplasm.
DNA contains the instructions for protein synthesis. RNA transcribes these instructions, which are then translated by ribosomes to assemble proteins. The rough ER helps in protein synthesis by providing a surface for ribosomes to attach, while the Golgi apparatus processes and packages the proteins for transport within or outside the cell.
Ribosomes are NOT located ON a protein. Ribosomes are organelles found in cells in/on which the cell synthesises (makes) proteins, using information that comes from the DNA in the cell's nucleus.
It is the messenger between DNA and the protein synthesis ribosomes
RibosomesProduces proteins.
mRNA (messenger Ribo-Nucleic Acid) carries the information to the ribosomes.
They use the ribosomes to connect strands from your DNA
The mRNA carries the genetic code needed to make a protein to the ribosome from DNA via microtubules.
