Which of the following sequences would pair best with 5'-AGCTTAGC-3? a. 5'-TCGAATCG-3'
b. 5'-UCGAAUCG-3'
c. 5'-AGCTTAGC-3'
d. 5'-GCUAAGCU-3'

. 5'-TCGAATCG-3'

Explanation:

Deoxyribonucleic acid consist of 2 Nitrogenous bases that pairs up during DNA formation.

We have purines and pyrimidine

Purine include Adenine and Guanine

Pyrimidine include Thymine and Cytosine

During base pairing, Adenine pairs with Thyamine and Guanine pairs Cytosine except in Ribonucleic acid where Uracil replaces Thymine.

Therefore the best pair is

5'-AGCTTAGC-3

. 5'-TCGAATCG-3'

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.
