Why is the RNA molecule copy of the DNA code for a polypeptide called messenger RNA?
Messenger RNA (mRNA) is named for its role in carrying the genetic information from the DNA in the cell nucleus to the ribosomes where protein synthesis occurs. It serves as the intermediary messenger that translates the genetic code into a specific sequence of amino acids to build a polypeptide chain.
What are the differences between DNA and mRNA and how do they function differently within the cell?
DNA is the genetic material that carries the instructions for making proteins in the cell, while mRNA is a temporary copy of a specific gene that carries the instructions from the DNA to the ribosomes for protein synthesis. DNA is double-stranded and located in the cell's nucleus, while mRNA is single-stranded and found in the cytoplasm. DNA remains in the nucleus, while mRNA travels to the ribosomes to direct protein synthesis.
How do you define protein synthesis?
Protein synthesis is the process by which cells build proteins using instructions encoded in the DNA. It involves two main steps: transcription, where a messenger RNA (mRNA) copy of the gene is made, and translation, where the mRNA is used as a template to assemble amino acids into a protein.
What role does the nucleus play in protein synthesis?
The nucleus is the site where DNA is stored and where transcription occurs, producing mRNA as a copy of a gene. This mRNA carries the genetic information to the ribosomes in the cytoplasm, where protein synthesis takes place. The nucleus does not directly participate in protein synthesis but is essential for providing the genetic information needed for the process.
Can you provide a comprehensive review of protein synthesis and mutations, highlighting the key concepts and mechanisms involved?
Protein synthesis is the process by which cells make proteins using instructions encoded in DNA. It involves two main steps: transcription, where a copy of the DNA sequence is made into messenger RNA (mRNA), and translation, where the mRNA is used to assemble amino acids into a protein. Mutations are changes in the DNA sequence that can affect protein synthesis by altering the mRNA or protein produced. These mutations can be caused by various factors, such as errors during DNA replication or exposure to mutagens. Understanding protein synthesis and mutations is crucial for studying genetic diseases and developing treatments.
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.

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.

What is the copy of the gene that moves to the cytoplasm called?
The copy of the gene that moves to the cytoplasm is called mRNA (messenger RNA). It carries the genetic information from the DNA in the cell nucleus to the ribosomes where protein synthesis occurs.
What are the differences between cDNA and CDS, and how do they impact gene expression and protein synthesis?
cDNA is a complementary DNA copy of an mRNA molecule, while CDS (coding sequence) is the part of the gene that encodes the protein. cDNA is used to study gene expression and can be used to produce proteins in recombinant DNA technology. CDS directly impacts protein synthesis by providing the instructions for the amino acid sequence of the protein.
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.
