Here's a taster:

The structure of nucleotides in RNA is the same as that of DNA except!
1.The ribose has an extra O atom
2.The organic base Uracil (U), replaces thyamine (T)
Making a nucleic acid strand (chain)
Condensation reactions join the nucleotide monomers together at the
phosphate groups to form one chain (strand) of nucleic acid polymer .…read more

Here's a taster:

Ribonucleic acid (RNA)
Other differences between RNA and DNA:
1.RNA molecules tend to be shortlived
2.RNA is found in the nucleus and in cytoplasm
3.Rna molecules are actively involved in the synthesis of proteins.
There are three different types of RNA
mRNA:messenger RNA
mRNA carries the genetic code from the DNA in the nucleus to the
ribosomes in the cytoplasm where the proteins are made.
mRNA is a single polynucleotide strand of about 1000 nucleotides long.…read more

Here's a taster:

RNA:ribosomal RNA
Ribosomes are made of rRNA+ protein
rRNA molecules can also form a double helix.
rRNA molecules are large and complex.
tRNA:transfer RNA
tRNA molecules are small only 80 nucleotides long.
tRNA molecules occur in the cytoplasm.…read more
