Many kinds of RNA are produced by cells. Here are some of the best known:
Messenger RNA (mRNA), which carries a copy of the code in a segment of DNA (a gene). Messenger RNA exists in more than one form, as it is modified by the cell, for example to cut out the introns.
Transfer RNA (tRNA): There have to be at least 20 of these, one for each amino acid. Each kind of transfer RNA carries a specific amino acid to a ribosome to be incorporated in a growing polypeptide chain. Ribosomal RNA (rRNA): Molecules of rRNA are made in the nucleolus, and they become the RNA component of a ribosome, the cytoplasmic organelle at which polypeptide chains are synthesized as the mRNA is translated.
A short strand of RNA is synthesized by the enzyme primase at the start of DNA replication. This is subsequently replaced by the corresponding DNA nucleotides.
There is an RNA (TERC) in the enzyme telomerase. This provides a template for the reverse transcriptase in telomerase to use as it extends telomeres.
There are also small nuclear RNAs, small nucleolar RNAs, and others.

How many different RNA are found in cells?
Cells have ribosomal RNA (rRNA), messenger RNA (mRNA), and transfer RNA (tRNA).
Where are genes found in the nucleus?
in DNA which codes RNA which is then sent out the pores of the nucleus so it can produce proteins for cells.
Is RNA found in mitochondria?
Yes Rna is found in mitichondria .It has all types of rna.It can produce produce proteins
What must cells produce to make large amounts of a particular protein?
Generally large amounts of messenger Rna {mRna} that code for the particular protein.
What does RNA synthesis produce?
nothing
Do prokaryotic cells contain RNA?
Yes. RNA is used by cells to make proteins. All living organisms produce proteins. In addition to prokaryotes, some viruses only use RNA as genetic material, but use the host cell to produce the proteins. These are called retroviruses like HIV.
What is the importance of a cells ability to copy a single DNA sequence into rna?
(Short Version) RNA makes it possible for a single gene to produce hundreds/ thousands of RNA molecules. -Gina(:
What is the important of the cells ability to copy single DNA sequence into RNA?
The ability to copy a single DNA sequence into RNA makes it possible for a single gene to produce hundreds or even thousands of RNA molecules.
How many different RNA are found in cells?
Cells have ribosomal RNA (rRNA), messenger RNA (mRNA), and transfer RNA (tRNA).
Where are genes found in the nucleus?
in DNA which codes RNA which is then sent out the pores of the nucleus so it can produce proteins for cells.
Is RNA found in mitochondria?
Yes Rna is found in mitichondria .It has all types of rna.It can produce produce proteins
What is the function of genetic material in a virus?
Viruses contain either DNA or RNA as their genetic material. Viruses containing RNA as their genetic material are called retrovirusesThe genome of a virus could either be:single or double stranded DNAsingle or double stranded RNA
Where is DNA and rna found?
In prokaryotic cells, DNA and RNA are both found in the cytoplasm. In eukaryotic cells, DNA is typically restricted to the nucleus and RNA is mostly in the cytoplasm.
What must cells produce to make large amounts of a particular protein?
Generally large amounts of messenger Rna {mRna} that code for the particular protein.
What does RNA synthesis produce?
nothing
Two types of RNA molecules are?
Four types are mRNA:messenger RNA tRNA:transfer RNA rRNA:ribosomic RNA and snRNA:small nuclear RNA(only in eukaryotic cells)
What is Total RNA?
Total RNA is purified RNA from tissue. It contains all the RNA of the cells. This is in contrast to purification containing only mRNA.
