If dna template reads agcttaagc, what is the nucleotide sequence of corresponding dna strands

The nucleotide sequence of a corresponding DNA strand would be TCGAATTCG.

It can be explained with the help of complementary base-pairing nature of the DNA strands that is, the nucleotide bases of the two strands are complementary in nature.

The purines (adenine and guanine) always base-pair with pyrimidines (thymine and cytosine).

More specifically, adenine always base-pair with thymine with the help of two hydrogen bonds and guanine always base-pair with cytosine with the help of three hydrogen bonds.

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.
