Answer the following statements true (T) or false (F)
1. Mutated p53 genes are found in more than half of all human cancer tumor cells.
2. Through examining the function and form of FtsZ and tubulin proteins, biologists can find evolutionary links between prokaryotes and eukaryotes.
3. An advantage of asexual reproduction is that it takes less time and energy than sexual reproduction.
4. After the crossover event in meiosis I, the recombinant sister chromatid is genetically identical to its parents.
5. The nuclei resulting from a mitotic division are genetically different from the original.
1. True
This statement is true. Mutated p53 genes are found in more than half of all human cancer tumor
cells.
2. True
This statement is true. Through examining the function and form of FtsZ and tubulin proteins, biologists can find evolutionary links between prokaryotes and eukaryotes.
3. True
This statement is true. An advantage of asexual reproduction is that it takes less time and energy than sexual reproduction.
4. False
This statement is false. After the crossover event in meiosis I, the sister chromatid is not
genetically identical to its parent chromatid; it has a combination of both its paternal and maternal genes.
5. False
This statement is false. The nuclei resulting from a mitotic division are genetically identical to the original.
