Plz and ! .if you have 40 cytosine in a sequence of dna, how many guanine do you have? lets say you know the sequences of the bases in one strand of the dna is: agctata, what is the sequence of the other strand?

Base pairing in DNA follows Chargaff’s rule. Cytosine on on strand pairs with guanine on other strand by triple bond. So, if you have 40 cytosine in a sequence of DNA, then number of guanine will be required is 40.

If the sequences of the bases in one strand of the DNA is AGCTATA, then the the sequence of the bases on the other strand will be complimentary to the bases on first strand. Bases sequence will be TCGATAT.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
