Answer:GGATCGA
Explanation:
The complementary double helix of the DNA are antipararell to each other.
Chargaff's rule state that Adenine always pairs with thymine (double bond) and Cytosine always pairs with guanine (triple bond).
Therefore if a DNA molecule is CCTAGCT, then the sequence on the complementary strand of DNA will be GGATCGA as written below
5' CCTAGCT 3'
3' GGATCGA 5'
Advantage: Dichotomous keys are very useful because they allow non-expert users to identify organisms by directing them to look at the known, important organisms. Disadvantage: Disadvantage of dichotomous keys is that if a single wrong decision is made at any juncture, a wrong identification will result. Sometimes it becomes obvious that an error has been made, and you can retrace your steps until you get back on the right track, but this is not always the case
Amino acid reactions. Amino acids via their various chemical functionalities can undergo numerous chemical reactions.
