Can somebody explain RNA to me?

We hardly went over it in class (finals seemed to happen very suddenly and everyone was like "oh!")

Hopefully there wont be munch about RNA on the final (it's tomorrow) but can you explain what it does, how it differs from DNA, etc?

Thanks so much!

    Study this and you should be good! :)

    RNA is a copy of DNA because DNA is to precious so they make copies

    RNA is single stranded, DNA is double stranded

    RNA has uracil instead of thymine as a nitrogenous base

    RNA uses ribose (one more sugar than DNA) whereas DNA uses deoxyribose

    RNA helps form proteins

    General knowledge:

    DNA are made of units called nucleotides linked together called, polynucleotides.

    3 things are required to make DNA

    -phosphate group

    -1 of 4 nitrogen bases (adenine, thymine, guanaine, cytosine)

    -a five carbon sugar molecule

    DNA forms a double helix

    RNA is a single stranded nucleic acid. It differs from DNA in that it is single stranded, has the base uracil not thymine, and it has the sugar ribose. It acts as an intermediary between DNA and the ribosome. The genes of DNA are transcribed into RNA , which then are translated into the amino acid sequences that make proteins.

    Hope that helps!
