l. Assuming you are working with the DNA from a single organism, in DNA gel electrophoresis the different bands in the final gel result because the DNA molecules . I. 2. 3. 4. are from different organisms have different lengths have different nucleotide compositions have different genes 2. Be as: low is a segment of DNA diagrammed without the sugars and phosphates. The base-pair (bp) sequence appears Read toward the right ACTCCGTAGAATTC T G A G G C A T C T T A A G? Read toward the left Compare the linear sequence of bases (As, Ts, etc.) in the upper DNA strand to those in the lower strand. Can you discover any relationship between the upper and lower strands? Describe it.Explanation / Answer
Answer:
1). 2. Have different lengths
Explanation:
Due difference in the length of DNA fragments, the DNA bands appear in gel electrophoresis. The movement of the DNA fragments depends on length of them. Small fragments move faster than the large fragments.
2). The DNA molecule clearly explains about Chargaff's rule as mentioned below.
Number of purines (A+G) = Number of pyrimidines (T+C)
A+G (8+6) = T+C (8+6)
14 = 14
Moreover, a polyndromic sequence can also be seen.
