Function, Structure & Types of RNA


Function, Structure & Types of RNA
~RNA=Ribonucleic Acid~
Fact
• Ribonucleotide in the RNA chain contains ribose(Sugar)
• Ribosomes are composed mostly of RNA
• Ribosomes compose up to about 60% of ribosomes 
by mass and providing the location where the mRNA binds
• The smallest RNA is usually about 70-90 nucleotides long
• Viruses may use RNA as it's genome 

Functions, Structure & Types 
The 3 main types of RNA are Messenger RNA (mRNA), 
ribosomal RNA (rRNA) and transfer RNA (tRNA)

 mRNA rRNA tRNA
 Structureshort, unstable, single-standard RNA, corresponds with gene encoded within DNA

 Long, stable RNA, molecules composing of 60% of ribosomes mass

 Short (70-90 nucleotides), stable RNA with base pairing. Contains amino acids and binding sites
 Function In between DNA and proteins; used by ribosomes to direct synthesis of proteins  Ensures the proper mRNA,tRNA, ribosomes during protein synthesis  Carries the correct amino acids to the active site of protein synthesis in the ribosomes

    1. The longest eukaryotic rRNA strand can only be as long as 5,000 nucleotides.
      The two largest genes in E coli are the beta and beta prime subunits of RNA polymerase (enzyme that changes its formation of a particular polymer). They encode themselves with the same mRNA. They have about 1,500 amino acids and 9,000 nucleotides
