NAME:
1) When a human somatic cell undergoes mitosis, it causes:
a) 4 cells with 46 chromosomes each
b) 4 cells with 23 chromosomes each
c) 2 cells with 46 chromosomes each
d) 2 cells with 23 chromosomes each
e) 4 cells, 2 with 46 chromosomes and 2 with 23 chromosomes
2) The phase of the life cycle of a cell in which the chromosomes reach the maximum degree of condensation and the best time to observe them is:
a) Interphase
b) Prophase
c) Anaphase
d) Metaphase
e) Telophase
3) Meiosis is necessary for sexual reproduction because:
a) Ensures the formation of paired chromosomes chromatids
b) It guarantees the transmission of the same characteristics to the daughter cells
c) Without it, the number of chromosomes would triple in each generation
d) Ensures the conservation of the number of chromosomes of the species
e) It is through it that the spores are produced
4) Check the difference between mitosis and meiosis that is correct
a) In meiosis prophase, chromosomes are double filaments; in mitosis prophase they are single filaments.
b) In mitosis, chromosomes do not divide; in meiosis they split
c) In meiosis anaphase, each chromosome has 2 chromatids; in mitosis anaphase, each chromosome has 4 chromatids
d) In the metaphase of mitosis, the chromosomes are paired; in the meiosis metaphase, the chromosomes are not paired
e) In meiosis, daughter cells are not identical to the mother cell; in mitosis, the daughter cells are identical to the mother cell
5) Which of the following processes occurs exclusively in meiosis?
a) Spiralization of chromosomes
b) Duplication of chromosomes
c) Chromosome pairing
d) division of the centromere
e) Migration of chromosomes along the spindle.
