If a segment of DNA is diagrammed without the sugars and phosphates, a base-pair

Question

If a segment of DNA is diagrammed without the sugars and phosphates, a base-pair sequence might appear as 5' 3' Read toward the right ACTCCGTAGAATT GAG GCATCTTAA GRead toward the left 5 Using the sequence shown previously, look at the linear sequence of bases on each of the strands I. Describe any pattern you might see in the upper sequence of bases. Compare the bases in the upper DNA strand to those in the lower strand. Can you discover any relationship between the upper and lower strands? Describe it. 2. 3. Now look at the upper sequence of bases and compare it to the lower. Do you notice any grouping of bases that when read toward the right on the upper strand and read toward the left on the bottom strand are exactly the same?

Explanation / Answer

1.no pattern is being observed.

2. There are two groups of bases that is purine and pyrimidine.
The purine nucleotides are adenine and guanine and pyrimidine nucleotides are cytosin and thymine.
there is the formation of double bond between adenine and thymine and the formation of triple bond between guanine and cytosine.
3. The basis of purine nucleotide are grouped together and that of pyrimidine nucleotides are grouped together separately.
