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.

What permits a single gene to code for more than one polypeptide?
Alternative splicing permits a single gene to code for more than one polypeptide. In alternative splicing, certain exons of a gene may be included or excluded from the messenger RNA used to code for proteins.
What is the form of RNA that carries the code from the DNA to the site where the proteins is assembled?
The mRNA carries information to the ribosomes. This is known as 'messenger' RNA because it carries the message, the base sequence from the nucleus to the ribosome. This mRNA is then translated into an amino acid sequence (polypeptide/protein) at the ribosome.
What is a segment of DNA that codes for a particular trait or protein?
A gene. DNA codes for messenger RNA: each DNA nucleotide complementarily hydrogen-bonds with RNA nucleotides. A codon is a segment of three nucleotides in the RNA molecule that carries the code of one amino acid. A codon complementarily and very specifically hydrogen bonds with the anticodon of a tRNA molecule. The amino acids encoded by the messenger RNA join to form a polypeptide chain through a polymerization process.
What are the 5 functions of DNA and RNA in protein synthesis?
DNA is transcripted into mrna which goes to a ribosome where trna matches up anticodons with mrna codons. the trna carries amino acids which eventually form a polypeptide chain. this polypeptide chain will combine with two or more polypeptide chains forming a fully funcional protein. ~Legit
What is the biological term for a nucleotide sequence which carries the code for a protein?
If the protein has a single chain of amino acids (known as a polypeptide chain), e.g. human growth hormone, then the term would be gene. A gene can be defined as a segment of DNA that codes for a polypeptide chain (or for a molecule of RNA, such as a molecule of transfer RNA or ribosomal RNA).If the protein has more than one chain, and the chains have different sequences of amino acids, then the code is carried in more than one gene: "one gene, one polypeptide".The nucleotide sequence that codes for just one of the amino acids in a chain is called a codon, and it consists of three adjacent nucleotides, often written just as the bases, because these are the only parts that differ between nucleotides. An example of a codon is CCA.
RNA that is a copy of DNA message that can enter the cytoplasm?
DNA code is copied to messenger RNA, abbreviated mRNA.
What molecule is used to take this DNA code out to the ribosome?
mRNA (messenger RNA) is the molecule that carries the copied code from the DNA in the nucleus to the ribosome.
What permits a single gene to code for more than one polypeptide?
Alternative splicing permits a single gene to code for more than one polypeptide. In alternative splicing, certain exons of a gene may be included or excluded from the messenger RNA used to code for proteins.
What is the code word for a messenger RNA called?
A codon

What molecule carries a copy of the code from out of the nucleus?
Molecules of Ribonucleic Acid (RNA) carry the instructions for assembling proteins out of the cell nucleus. Without this type of molecule, the cell cannot survive.
Role of mRNA during protein synthesis?
copies the genetic code from the DNA molecule and carries it to the ribosome
What is The from of RNA that carries the code from DNA to the site of Protein assembly is called?
Messenger RNA

What is the name for a large polymer of nucleotides that provides the code for making proteins?
DNA.It is the sequence of bases along the DNA molecule that codes for the sequence of amino acids in a polypeptide chain. One or more polypeptide chains, when they have correctly coiled and folded, and, if necessary, assembled together, form the functional molecule that we call a protein.In some viruses the genetic information is stored in RNA, not DNA, so a more accurate answer would be a nucleic acid.
