RNA

Ribonucleic Acid

RNA

Single stranded Nucleic acid made of repeating

nucleotides Sugar = ribose No thymine have Uracil instead U bonds with A

So DNA vs. RNA

DNA RNA

Double stranded

Has Thymine

Sugar= deoxyribose

NEVER leaves the nucleus

Single stranded

Has Uracil

Sugar= ribose

Leaves the nucleus

3 Types of RNA

mRNA

tRNA

rRNA

mRNA- Messenger RNA- • RNA copy that carries information from DNA in

nucleus out into the cytoplasm of the cell

rRNA- Ribosomal RNA- • The RNA that

composes ribosome, helps produce enzymes needed to bond amino acids together during protein production

tRNA- Transfer RNA- • Brings amino acids to the ribosomes so they

can assemble into proteins
