During dna replication, what sequence of nucleotides would bond with the dna sequence aggtacga? why?

Well in the case of DNA replication it would be TCCATGCT

Explanation:

For DNA strands A pairs with T and C pairs with G so the other pair always goes on the other strand to make a matching strand of DNA.

TCCATGCT

Explanation:

TCCATGCT nucleotide sequence will bond with DNA sequence AGGTACGA during DNA replication. It is because A is complimentary to T and vice versa & C is complimentary to G and vice versa. The complementarity is totally based on the shapes of the nucleotides which fits the need of DNA double helix formation. A binds with T with the help of 2 hydrogen bonds (A=T) while C binds with G with the help of 3 hydrogen bonds (C≡G).  

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
