How is dna compressed into chromosomes
WebThe ends of the chromosomes pose a problem as polymerase is unable to extend them without a primer. Telomerase, an enzyme with an inbuilt RNA template, extends the ends by copying the RNA template and extending one end of the chromosome. DNA polymerase can then extend the DNA using the primer. In this way, the ends of the chromosomes … Web25 mrt. 2024 · Each human body cell contains 46 chromosomes. These can be arranged into 23 pairs.
