simply because DNA molecules cannot fit outside of the nucleus therefore Rna is needed

Explain three characteristics that distinguish DNA of rna?
ok so DNA cannot leave the nucleus it will be destroyed if it does rna is a copy of DNA rna has three dif groups trna mrna rrna (transfer messanger and ribosomal nucleic acid)
Why is RNA necessary to act as a messenger?
Because it receives genetic information from DNA by transcription. This is how DNA sends genetic information to the cell organelles to perform specific functions.
What Enzyme is necessary in transcribing mRNA from DNA?
RNA polymerase
Where does the RNA strand originate from?
RNA has sub-division such as m-RNA(messanger RNA) which i learned it conducts a copy of the genetic information (in other words it makes a copy of DNA because DNA cannot go out of the NUCLEUS)
There are three different forms of RNA?
Messanger RNA - Molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes).Ribosomal RNA - Molecule in cells that forms part of the protein-synthesizing organelle known as a ribosome and that is exported to the cytoplasm to help translate the information in messenger RNA (mRNA) into protein.Transfer RNA - Small molecule in cells that carries amino acids to organelles called ribosomes.
What are the three kinda of RNA?
The three types of RNA are: mRNA (messanger RNA), rRNA (ribosomal RNA), and tRNA (transfer RNA).
What is messanger RNA?
Carries the DNA message from the nucleus to the ribosome.
A part of a cell the sends messages from the nucleus to the cytoplasm is?
Messanger RNA
What type of RNA makes a copy directly from DNA?
mRNA, which stands for messanger rna. this RNA is the one who takes the codes out of the nucleus and into the cytoplasm.
How does a cell get the genetic code from its location to the site of protein synthesis?
By messanger RNA
What is the job of Messanger RNA?
Messenger RNA (mRNA) is a molecule of RNA encoding a chemical "blueprint" for a protein product. mRNA is transcribed from a DNA template, and carries coding information to the sites of protein synthesis: the ribosomes.
What does mRNA stand for and why does it have to be made?
Messanger RNA and it sends the messages for the DNA because the DNA cannot leave the nucleus
Which purine or pyrimidine bases are not present in the messanger RNA m-RNA is it adenine or guanine or cytosine or thymine or uracil?
thyamine isn't present in mRNA its place is taken by uracil
What carries a specific code from the nucleus to the site if protein synthesis?
The DNA bases provides a code for proteins.
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 the process of transcription DNA serves as a template for making fill in the bank which leaves the nucleus and travels to the ribosomes?
mRNA (messanger RNA)
What are the base codes for messenger RNA?
In Messanger RNA there are 4 bases Adenine Uracil Guanine Cytosine Adenine pairs with Uracil Guanine pairs with Cytosine In DNA there is no Uracil but instead Thymine, hope this helps
