RNA molecules are basically a cheap, yet reliable copy of your cell's DNA.
To understand why RNA molecules are needed, you must first know that DNA is very precious. It is the only copy of instructions you cell has. Without it, everything your cells do would cease to happen, and your cells would shut down.
Because it's so precious, DNA can't leave the protection of the nucleus, because there's too great a risk that it would be hurt. So, it makes a generic but identical copy of itself into RNA, which can travel unharmed throughout the cell.
Once copied, RNA travels though the cell to places like your ribosomes, and tells them how to put together amino acids in order to make proteins, the building blocks of your cell.
What else can I help you with?
What has the instructions for assembling proteins?
They are on DNA. DNA is in nucleus
What is The type of RNA that carries information from DNA to the ribosome of a cell is known as?
The type of RNA that brings instructions from DNA in the nucleus to the cytoplasm is messenger RNA or mRNA.
Where is the DNA in your cells?
In my cell, DNA is located in the nucleus, where our 46 chromosomes reside. However, there is also DNA in the mitochondria, in many copies of a circular DNA about 17,000 base pairs long (with some partial single stranded regions).
What molecule copies the DNA coding strand and leaves the nucleus?
mRNA copies the information.Process is called transcription.
How does the nucleus relate to DNA?
The nucleus is the "control center" of the cell. It tells the cell how to function and chromosome development. Chromosomes contain the genetic or hereditary instructions. Chromosomes are both composed of nucleic acids and protein. The nucleic acid in protein is called deoxyribonucleic acid (DNA). DNA is stored in the Nucleus. It is not allowed to leave, for it to be used it must be copied. Short single stranded copies of one of the two DNA strands in the nucleus are made from ribonucleic acid (RNA). these copies represent detailed messages that can be transported out of the nucleus. (as mRNA)
Which types of RNA copies DNA's instructions In the nucleus?
Messenger RNA (mRNA) copies DNA's instructions in the nucleus.
Which type of RNA copies DNA's instrutions in the nucleus?
mRNA (messenger RNA) carries a copy of the DNA from the nucleus to the ribosomes.
What eukaryotic cells RNA is copies from DNA in the?
the nucleus i believe

Where within the cell are the DNA instructions located?
The Nucleus.
What is the term for DNA after it has left the nucleus?
The DNA found in the nucleus does not leave the nucleus. Instead, a copy of this DNA is carried on mRNA out of the nucleus and to the ribosomes. By keeping the DNA in the nucleus, it is protected from degradation - so a "master copy" of the instructions can be kept safe.
What molecule copies the DNA coding strand and leaves the nucleus?
mRNA copies the information.Process is called transcription.
Where are the instructions to form new cells?
In the DNA contained in the nucleus.

What makes sure a cell gets all its DNA?
nucleus provides instructions to make DNA
