Question

how are DNA and RNA different in terms of function, #strands, and sugars

Answer 1

In terms of structure, RNA and DNA are similar. They consist of 5 carbon sugars connected via phosphate groups with a nitrogenous base attached. The difference is that RNA has ribose as a sugar and DNA has deoxyribose, DNA does not have the 2' hydroxyl group that RNA does (hence the name, it is missing one oxygen.) This actually makes DNA more stable than RNA though. The other difference is in the bases. DNA has adenine, cytosine, guanine and thymine. RNA has the same except that it uses uracil in place of thymine.

DNA is the central genetic material of life. It is basically blue prints to your existence. To be really basic, its essential function is to store information.

RNA does a lot of the work. RNA is transcribed from a DNA template which is then used by ribosomes to create proteins, the real workhorse of life. These types of RNA are called mRNA (messanger RNA), tRNA (transfer RNA, carries amino acids to growing polypeptide chains/ribosomes) and rRNA (ribosomal RNA, a part of ribosomes.)

Answer 2

DNA
single stranded
sugar is deoxyribose
found in nucleus
funcion: genetic material, basic molecule for sustaining life. also is used as template for RNA, which is what proteins are made from.

RNA
single stranded
sugar is ribose
found in nucleus --> mRNA eventually makes its way into cytoplasm
rRNA is found in ribosome
mRNA is found in mitochondrea
funtion: uses DNA as a template to construct mRNA molecule, takes it to the rRNA where tRNA meets up with it, bringing amino acids that match up with codons on mRNA and the main funtion through all of this is to make proteins, which are essential to the function of life
