Question

37. Which of the following statements applies to homologous chromatids? A. They are attached to the same centromere B. They are genetically identical C. They segregate from each other at anaphase of mitosis D. They contain the same genes in the same order but may have different alleles of som E. More than one statement applies to homologous chromatids 38. Match the event with the appropriate stage of mitosis Sister chromatids separate and move to opposite poles Chromosomes begin attaching to spindle fibers Chromosomes decondense and puclear membrane re-formse metaphase Chromosomes condense and spindle forms Sister chromatids attach to opposite spindle poles anaphase telophase 39. Match the chromosomal event with the appropriate stage of meiosis Homologous chromosomes pair and cross over 2Homologous chromosomes segregate to opposite poles Sister chromatids segregate to opposite poles Pairs of chromosomes attach to spindle fibers from opposite po Sister chromatids attach to spindle fibers from opposite poles sc b.metaphase I anaphase1 metaphase 1 anaphase L

Explanation / Answer

Ans37)Option E- More than one statement apply

Statements that apply are-A,C,D

Homologous chromatids are attached to same centromere,they segregate at anaphase and contain the same genes in same order but may have different alleles.

Ans38)(1-d)Sister chromatids seperate and move to opposite poles in anaphase.

(2-b)Chromosomes begin attaching to spindle fibres in prometaphase

(3-e)Chromosomes decondense and nuclear membrane reappears in the last step that is telophase

(4-a)Chromosomes condense and spindle forms in the first step which is prophase.

(5-c)Sister chromatids attach to spindle fibres from opposite poles in metaphase.

Ans39)(1-a)-Homologous chromosomes pair and cross over in prophase1

(2-c)-Homologous chromosomes move to opposite poles in anaphase 1

(3-e)Sister chromatids segregate to opposite poles in anaphase-2

(4-b)Pair of chromosomes attach to spindle in metaphase1

(5-d)Sister chromatids attach to spindle in metaphase2
