3. In what cells do meiosis and mitosis take place?
4. If one strand of DNA, had bases ordered ATCCGTC, what would be the bases of its other strand?
3. Meiosis and mitosis both occur in cells called eukaryotic cells. However, they take place in different types of cells within multicellular organisms.
Mitosis occurs in somatic (non-reproductive) cells, which make up most of the cells in the body. This includes cells in tissues like skin, muscles, and organs. The purpose of mitosis is to produce two identical daughter cells, each with the same number of chromosomes as the parent cell.
Meiosis, on the other hand, takes place in specific cells called germ cells, which are found in the reproductive organs of organisms. In humans, these would be the testes in males and the ovaries in females. The purpose of meiosis is to produce gametes (sex cells), such as sperm and eggs, which have half the number of chromosomes as the parent cell.
4. To determine the bases of the other strand of DNA, you need to understand the base pairing rules of DNA. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).
So, to find the bases of the other strand, you can use the following base pairing:
A pairs with T
T pairs with A
C pairs with G
G pairs with C
In this case, if the given strand has the bases ATCCGTC, the other strand would have the following bases:
T pairs with A (since A pairs with T)
A pairs with T (since T pairs with A)
G pairs with C (since C pairs with G)
G pairs with C (since G pairs with C)
C pairs with G (since G pairs with C)
A pairs with T (since A pairs with T)
So, the bases of the other strand would be TAGGCAA.
