If the sequence of the 5'-3' strand is aatgctac, then the complementary sequence has the following sequence:
3'-aatgctac-5'
3'-catcgtaa-5'
3'-ttacgatg-5'
3'-gtagcatt-5'

3'-TTACGATG-5'

Explanation:

The DNA sequence is in couples where A is united T and G is united C, so what we do is replace in the complementary sequence the original nucleic acids, remember A-T, G-C.

5'-AATGCTAC-3'

3'-TTACGATG-5'

To remember: the DNA sequence is 5'-3' in one sequence and its complementary is inverse, what means it goes 3'-5'.

Also the T-A is united by 2 hydrogen bonds, and G-C is united by 3 hydrogen bonds.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
