RNA is a single stranded molecule, composed of a ribose sugar phosphate backbone (as opposed to the deoxyribose sugar phosphate double-stranded DNA) and the bases, adenine, guanine, cytosine and uracil (i...

The fluid mosaic model is a model used to describe the cell membrane and the transport of molecules through it. It is a semi permeable membrane which means that it is selective in the molecules that it al...

The structure of mRNA differs from the structure of DNA in that mRNA is a single-stranded molecule whereas DNA is a double-stranded molecule in the form of a helix. Another difference between them is that...

The genetic fingerprint is differentiated based on the differing lengths of short tandem repeats (STRs) between genes. Everyone has different lengths of STRs so when their DNA is hydrolysed by restriction...

Water molecules are dipolar - they have both positively charged and negatively charged regions due to differences in the electronegativity of atoms (this is how strongly they attract electrons). This prop...
