D. 8 B. 4 69. CDKs are important in the regulation of the cell cycle. They carry out their function by A. adding phosphate groups to target proteins B. degrading cyclin proteins C preventing the progression of a cell from one stage of the cell cycle to the next D. removing phosphate groups from target proteins 70. Which of the following statements concerning cyclin-dependent kinases (COKS) is NOT true? 70. Which of the following statements concerning cyclin-dependent kinases (CDKs) is NOT true? A. Specific CDKs pair with specific cyclins. B. CDKs are active, or "turned on", when complexed with cyclins. C. CDKs are present throughout the cell cycle. D. CDKs are inactive, or "turned off", in the presence of cyclins 71. Levels of Cdk activity change during the cell cycle, in part, because A. B. C. D. the Cdks phosphorylate each other the Cdks activate the cyclins Cdk degradation precedes entry into the next phase of the cell cycle cyclin levels change during the cycle in the body. Answer t in the following list for a human cell The human genome comprises 23 pairs of chromosomes found in nearly every cell he quantitative questions below by choosing the letter for one of the numbers in the following list for a in G2 of the cell cycle: A. 23 B. 46 C. 92 D. 184 E. 1000 72. How many centromeres are in each somatic/body cell (not a gamete)? 73. How many telomeres are in each somatic/body cell (not a gamete)? 74. According to the principle of segregation, a heterozygous plant with alleles Aa will produce: A. gametes with only the A allele. B. gametes with only the a allele. C. 50% ofgametes with the A allele and 50% of gametes with the a allele, on average. D. gametes in the ratio of 3 A alleles:1 o allele. E. some gametes with the A allele and some with the a allele, but in no predictable ratio. 75. If you crossed two heterozygous yellow seed pea plants (genotypes Aa): A, the relative frequency of the o allele in each parent's gametes would be ½. B, the relative frequency of the A allele in each parent's gametes would be y. C, the relative frequency of green seed plants (genotype aa) would be 54. D. the relative frequency of homozygous yellow seed plants (genotype AA) would be ¼. E. All of the answer options would be true.Explanation / Answer
67 ) Interphase is divided into G1,S and G2 phase.G1 is about cell growth and G2 is about cell division.
the correct answer is B
68 ) the correct answer is A
69 ) CDks add phosphate group to target protein.
So correct answer is A
70 ) CDKs are also known as cyclin dependent kinase ,they are family of multifunctional enzymes and they require the presence of cyclins to become active.
So correct answer is D
