🧬 DNA Doubles... But Chromosome Number Doesn't? 🤯 | Biology Explained #Shorts

🧬 Did you know that during the S Phase, the DNA content doubles but the chromosome number remains the same? 🤯

Many students find this concept confusing, but the explanation is simple!

During the S Phase of the Cell Cycle, each chromosome replicates to form two identical sister chromatids joined together by a centromere. Since the sister chromatids remain attached, they are still counted as one chromosome. Therefore, DNA content doubles, but the chromosome number remains unchanged until the chromatids separate during cell division.
