Why is the RNA molecule copy of the DNA code for a polypeptide called messenger RNA?
mRNA carries a copy of the instructions from the DNA in the nucleus to the ribosomes, where protein synthesis occurs. It is known as messenger RNA because it is delivering the message - the instructions for protein synthesis - to the ribosomes.
Why is it more important to check for Error during DNA replication and then during protein synthesis?
Because during replication a new copy of the DNA is made form which proteins will eventually be synthesized. Replication copies the mistake, synthesis merely empresses it.
Which describes the flow of information in protein synthesis?
The correct molecular involved in protein synthesis is DNA, messenger RNA, transfer RNA, and polypeptide. When a DNA is read, it produces a messenger RNA, amino acids are then matched with codons (transfer RNA) forming chains of polypeptides.
Rna that copy of the DNA message that can enter the cytoplasm?
Transcription is the synthesis of RNA under the direction of DNA. The type of RNA used during transcription is the messenger RNA. The mRNA carries a genetic message from the DNA to the protein-synthesizing machinery of the cell. Then, translation is the actual synthesis of a polypeptide, which occurs under the direction of mRNA.
What controls the production of enzymes?
An enzyme is a protein. First of all, RNA which is a copy of DNA is formed to be translated by ribosomes. Each 3 letters form a specific amino acid. These amino acids are combined together by RNA to form a protein.
What is the product of transription and translation?
The product of transcription and translation is the synthesis of a protein. Transcription produces a mRNA copy of a gene, which is then translated by ribosomes into a specific sequence of amino acids to form a protein.
What tasks does messanger RNA perform during protein synthesis?
mRNA carries a copy of our DNA, our genetic information and is used in the synthesis of these proteins.
Why is the RNA molecule copy of the DNA code for a polypeptide called messenger RNA?
mRNA carries a copy of the instructions from the DNA in the nucleus to the ribosomes, where protein synthesis occurs. It is known as messenger RNA because it is delivering the message - the instructions for protein synthesis - to the ribosomes.
During protein synthesis what carries a copy of DNA's blueprint into the cytoplasm?
I think it is mRNA. Not sure though.
What molecule turns DNA to protein?
DNA doen't leave the nucleus but a copy of the segment (called mRNA) that codes for the protein leaves the cell and meets up with a ribosome. The ribosome will translate the copy of the DNA into a specific protein.
Why is it more important to check for Error during DNA replication and then during protein synthesis?
Because during replication a new copy of the DNA is made form which proteins will eventually be synthesized. Replication copies the mistake, synthesis merely empresses it.
Using RNA as a template for protein synthesis instead of translating proteins directly from the DNA is advantageous for the cell because?
RNA acts as an expendable copy of the genetic material.
Where is DNA changes to RNA?
DNA changes to RNA when the nucleus is going through protein synthesis. in order for your ribosomes to make protein they must copy a portion of your DNA, change it into RNA then translate the RNA into amino acid sequences which come all together to make a protein ...
When is a copy of DNA necessary?
ANSWER: A copy of DNA is necessary in the process of protien synthesis.
What is the name of the process of building up large proteins in a cell?
Protein synthesis requires two steps: transcription and translationMessenger RNA (mRNA) a copy of a portion of the DNA. It carries genetic information from the gene (DNA) out of the nucleus, into the cytoplasm of the cell where it is translated to produce protein. Proteins are created by ribosomes translating mRNA into polypeptide chains. These polypeptide chains undergo PTM (Posttranslational modification) to give the mature protein.
Which describes the flow of information in protein synthesis?
The correct molecular involved in protein synthesis is DNA, messenger RNA, transfer RNA, and polypeptide. When a DNA is read, it produces a messenger RNA, amino acids are then matched with codons (transfer RNA) forming chains of polypeptides.
Where is information for protein synthesis stored?
The instructions for making proteins are all packaged within regions in our DNA (in the nucleus). When it's time to make a protein, enzymes read these instructions and make a little copy of the specific code for this specific protein, which then exits the nucleus where 'ribosomes' read these instructions and begin manufacturing the protein. Therefore, the entire set of original instructions are found in the nucleus (in DNA); but it is important to remember that there are lots of little copied segments in the cytoplasm that code for just one protein each.
