Adouble-stranded dna molecule contains bases with a ratio of (a + t)/(g + c) = 3: 1. this molecule is replicated with dna polymerase in the presence of the four deoxynucleoside triphosphates with a molar ratio of (a + t)/(g + c) = 1: 1. what is the expected ratio of (a + t)/(g + c) in the double-stranded daughter dna molecule?

3:1

Explanation:

DNA replication is a semi-conservative process of making the DNA copies of existing parental DNA strands. The process of DNA replication makes the complimentary copy of template DNA strand. Therefore, the ratio of (A + T)/(G + C) in parental DNA and daughter DNA double helices would be same.  

According to the question, the parent DNA strand has a ratio of (A + T)/(G + C) = 3:1. The daughter DNA molecules formed by replication of this parent DNA would also have (A + T)/(G + C) bases in 3:1 ratio.

explanation:

earthquakes in florida are rare because the state is not located near any tectonic plates. in fact, florida is tied for first place as having the fewest earthquakes of any state. much of florida is limestone and seafloor materials that is not conducive to earthquakes.
