| 41. | The sister chromatids will be distributed to each daughter cell at the end of the cell division.
|
| 42. | SDSA recombination involves information exchange between paired non-sister homologous chromatids, but not physical exchange.
|
| 43. | Proper cohesion of sister chromatids is a prerequisite for the correct segregation of chromosomes during cell division.
|
| 44. | Normally, the chromosomes are single-stranded, so there is one chromosome and one chromatid.
|
| 45. | If you have 46 pairs of chromosomes, they first replicate their DNA to form 92 chromatids.
|
| 46. | Diethylaniline may be genotoxic because it has been found to increase the rate of sister chromatid exchange.
|
| 47. | Therefore, the resulting sister chromatids cannot separate from each other and cannot divide into 2 daughter cells.
|
| 48. | First, the cell undergoes DNA replication, so each homolog now consists of two identical sister chromatids.
|
| 49. | During homologous sites on two chromatids can closely pair with one another, and may exchange genetic information.
|
| 50. | The centromere is required for binding spindle fibres to separate sister chromatids into daughter cells during cell division.
