Answer: Dna Structure And Function Worksheet Ap Biology

The purine-to-pyrimidine ratio is always 1:1 in a double-stranded DNA molecule (Chargaff’s rule). Part 2: DNA Function (Replication & Central Dogma) Question 5: Explain the role of the following enzymes in DNA replication:

If one strand of DNA has the sequence 5’-ATTCGAGC-3’, what is the complementary strand? Be sure to label the 5’ and 3’ ends.

What type of bond holds the two strands of DNA together? Why is this bond important for DNA replication? Dna Structure And Function Worksheet Ap Biology Answer

Compare and contrast the leading strand and the lagging strand .

Semiconservative replication means that each new DNA double helix contains one original (parental) strand and one newly synthesized daughter strand . This was proven by the Meselson-Stahl experiment using isotopic nitrogen (¹⁵N and ¹⁴N). The purine-to-pyrimidine ratio is always 1:1 in a

Why is DNA replication considered semiconservative ?

The complementary strand is: 3’-TAAGCTCG-5’ What type of bond holds the two strands of DNA together

| Purines (two rings) | Pyrimidines (one ring) | |---------------------|------------------------| | Adenine (A) | Cytosine (C) | | Guanine (G) | Thymine (T) | | (Also Uracil in RNA)| |
