Cell division is super important for growth, repair, and reproduction in living things. DNA plays a big part in this process. Let’s make it simple!
DNA stands for deoxyribonucleic acid. It is the molecule that holds all the genetic information we need to grow and function.
Imagine DNA as a twisted ladder, called a double helix. Each step of the ladder is made up of pairs of bases. The bases are:
When cells divide, DNA must be copied so that each new cell gets an exact copy of the genetic information. Here’s how it happens:
Replication: First, the double helix unwinds. Each strand acts as a guide to make a new matching strand. For example, if one side has A-T-C-G, the new side will be T-A-G-C.
Distribution: Then comes mitosis. This is when the copied DNA is split evenly into two new cells, called daughter cells. This ensures both cells have the same DNA, which is important for keeping the organism’s traits.
This process is very important for everything to work smoothly. If there are mistakes when DNA is copied, it can cause mutations. These mistakes might lead to diseases or growth problems.
Overall, DNA is not just a blueprint of life; it also makes sure this blueprint is correctly passed on when cells divide!
