If one strand of DNA, had bases ordered ATCCGTC, what would be the bases of its other strand?
Compare and contrast mitosis and meiosis as to: number of divisions, number of cells produced, number of chromosomes in parent cells and in gametes.
Sure! Let's break down each question and I'll guide you on how to find the answers.
Question 1: If one strand of DNA had bases ordered ATCCGTC, what would be the bases of its other strand?
To find the bases of the other DNA strand, it's important to remember the complementary base pairing rule in DNA. In DNA, adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G).
So, given the original strand ATCCGTC, the bases of its complementary strand would be TAAGCAC. This is because A pairs with T, T pairs with A, C pairs with G, and G pairs with C.
Question 2: Compare and contrast mitosis and meiosis as to the number of divisions, number of cells produced, number of chromosomes in parent cells, and in gametes.
To compare and contrast mitosis and meiosis, focus on the following aspects:
1. Number of divisions: Mitosis involves one cell division, whereas meiosis involves two cell divisions.
2. Number of cells produced: Mitosis produces two diploid (identical) daughter cells, while meiosis produces four haploid (non-identical) daughter cells.
3. Number of chromosomes in parent cells: In mitosis, the parent cell has a diploid number of chromosomes (full set), while in meiosis, the parent cell also has a diploid number, but it divides twice to form haploid cells.
4. Number of chromosomes in gametes: Mitosis does not directly produce gametes, while in meiosis, the four haploid daughter cells are gametes with half the number of chromosomes compared to the parent cell.
By comparing these aspects, you can highlight the differences between mitosis and meiosis.
