DNA is made up of deoxyribose sugar while mRNa is made up of ribose sugar. DNA has thymine as one of the two pyrimidines while mRNA has uracil as its pyrimidines base. DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis. DNA is double stranded while mRNA is single stranded.
Hope this is helped ;)
Huh ??? please provide more information
<span>The different adrenal hormones show selectivity for different types of adrenergic receptors. This may be because the chemical structures of the adrenal hormones are such that binding is biochemically easier for the hormones at the receptors to which they show a selective affinity.</span>
The best answer is "foreshocks before the quake and aftershocks after the quake".
These terms are used to characterise the events of an earthquake over time. Foreshocks are small shocks that can occur before the main seismic event. Aftershocks, like foreshocks, are smaller seismic events that can occur after the main seismic event.
