A skin cell in G2 of interphase has twice as much DNA as it had in G1.
A skin cell is somatic cell that undergoes mitosis (cell division). Mitosis together with interphase is part of the cell cycle.
Interphase also known as a phase for the preparation for division consists of three phases:
• G1- cell becomes larger, copies organelles, and makes the building blocks necessary for the new cell
• S-cell copies its DNA in the nucleus (that is why G2 phase has twice as much DNA as it had in G1)
• G2 – cell continues to grow, makes proteins and organelles.
During the mitosis, the cell separates its DNA into two and divides its cytoplasm, forming two new daughter cells.
Answer:
Its width.
Explanation:
The size of pyrimidines and purine is different because each group has a different structure (1 or two rings). Therefore, the width of DNA is "constant".
If we would pair two pyrimidines or two purines, the width of DNA would be different in both cases.
Hope this will help :)
