DNA Structure
DNA (deoxyribonucleic acid) is a molecule that contains the instructions for an organism’s development and characteristics. It is made up of two long chains of nucleotides, twisted together to form a double helix. Each nucleotide consists of a sugar molecule, a phosphate molecule, and a nitrogenous base.
The four nitrogenous bases are adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up with each other in a specific way: A with T, and C with G. This pairing is what gives DNA its double helix structure.
DNA Replication
DNA replication is the process by which a cell makes a copy of its DNA. This process is essential for cell division, as each new cell needs its own copy of the DNA. DNA replication begins when the DNA double helix unwinds and the two strands separate.
Each strand then serves as a template for the synthesis of a new strand. The nucleotides in the new strand are added in a complementary fashion, so that the new strand is identical to the original strand.
Enzymes in DNA Replication, Dna molecule and replication worksheet
Several enzymes are involved in DNA replication. One of the most important enzymes is DNA polymerase. This enzyme adds nucleotides to the new strand in a complementary fashion. Other enzymes involved in DNA replication include helicase, which unwinds the DNA double helix, and ligase, which joins the new strands together.
Significance of DNA Replication
DNA replication is essential for cell division. Without DNA replication, each new cell would not have its own copy of the DNA, and the cell would not be able to function properly. DNA replication also plays a role in DNA repair.
When DNA is damaged, the cell can use the undamaged strand as a template to repair the damaged strand.
FAQ Explained: Dna Molecule And Replication Worksheet
What is the role of nucleotides in DNA?
Nucleotides are the building blocks of DNA, consisting of a sugar molecule, a phosphate group, and a nitrogenous base. The sequence of these bases determines the genetic code.
How does DNA replication occur?
DNA replication is a semi-conservative process where each original DNA strand serves as a template for the synthesis of a new complementary strand.
Why is DNA replication important?
DNA replication is crucial for cell division, ensuring that each daughter cell receives an identical copy of the genetic material.
