Select the statement s that correctly describe s the role of p21 Which if the following correctly describes the role of p21 p21 is produced in response to increasing levels of Rb p21 levels increase as levels of oncogenes increase p53 triggers the production of p21 which regulates Cdk activity p21 regulates the fluctuations seen in the cyclins in the cell cycle

Select the statement that incorrectly describes p53 The tumor suppressor protein p53 detects DNA damage prior to the mitotic phase of the cell cycle Defective p53 cannot trigger apoptosis Mutated p53 may cause cells with DNA damage to continue to divide Normal p53 will stop the cell cycle when DNA damage is detected Mutated p53 may cause cells to become cancerous

Select the statements that correctly describe retinoblastoma and p21 Rb reinforces the effect of p53 by binding to Cdk cyclin complexes 0 As levels of p53 increase the production of p21 is triggered The combined effect of p53 and p21 prevent the cell from entering the S phase of interphase Rb is active when it is dephosphorylated and bound to transcription factors Rb is activated when the cell is at a very small size Rb and p21 are examples of positive controls of the cell cycle

10 Tetras are popular tropical fish to raise and breed as a hobby A tetra breeder has a set of dihyb females that have blue eyes and long tail fins She uses these to do a testcross to males that are homozygous for the recessive alleles for black eyes b b and short tail fins tt The following numbers of each type were born 321 with blue eyes and short tail fins 44 with blue eyes and long tail fins 376 with black eyes and long tail fins and 52 with black eyes and short tail fins From these data the breeder can deduce that in the dihybrid parent the alleles are a linked in Cis b linked in Trans c not linked 11 The lengths of chromosomes differ from one species to another In one the longest chromosome is 294 map units long while the shortest is 102 map units in length a True b False This means that alleles at the tips of each chromosome in this species essentially show independent assortment
