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.
Hydrogen bonds are relatively weak, allowing the two strands to be easily “unzipped” by enzymes like helicase without breaking the covalent bonds (phosphodiester bonds) within each strand. This allows each strand to serve as a template. Dna Structure And Function Worksheet Ap Biology Answer
The complementary strand is: 3’-TAAGCTCG-5’ If one strand of DNA has the sequence
Why is DNA replication considered semiconservative ? This allows each strand to serve as a template
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:
Let’s dive into the answers and explanations. Question 1: Draw and label a nucleotide. What are the three components?
Hydrogen bonds hold the two strands together. Specifically, two hydrogen bonds form between A and T, and three hydrogen bonds form between G and C.
