3 simple steps for DNA duplication
I have found so many answers but cant get a concise one.
1. separation - of 2 dna strands unzips
2. duplicates
3. zips back up
and then a simple sentence about each
Sure! Here are three simple steps for DNA duplication, along with a simple sentence explaining each step:
1. Separation: The two DNA strands "unzip" or separate from each other.
- To accomplish this, the hydrogen bonds between the complementary bases of the two DNA strands (adenine pairs with thymine, and guanine pairs with cytosine) are broken.
2. Duplication: Each separated DNA strand serves as a template for the creation of a new complementary strand.
- Enzymes called DNA polymerases add nucleotides to the exposed bases on each template strand, creating two new strands that are identical to the original strands.
3. Zipping back up: The newly synthesized strands combine with their respective template strands, forming two complete DNA molecules.
- The hydrogen bonds between the complementary bases of the original and newly synthesized strands reform, effectively "zipping" the two strands back together.
By following these three steps - separation, duplication, and zipping back up - DNA replication takes place, ensuring the accurate and complete duplication of genetic information.
