4. Fill in the fourth column (inversion) of the table. Chromosomal Mutations Translocation Deletion Inversion 1. How many chromosomes are involved? 2. How did you change the original structure of the chromosomes? 3. Which condition/s do you think result/s to change/s of chromosome material? Please indicate using the words loss, gain, either loss or gain of genetic material.

Which of these changes in chromosome structure alter the total amount of genetic material?

1.Describe the rearrangement in chromosomes A-C. indicate the specific markers genes flanking the crossover/breakage points (e.g., a translocation with breakpoints between markers X and Z). 2.Chromosome rearrangements can be caused by crossing over between repetitive DNA sequences. Draw a picture similar to Figure showing how crossovers between repetitive sequences could have produced chromosome rearrangement A. indicate the location and orientation of the repetitive DNA segments relative to the marker genes.

6.6 Describe crossing over. Explain how it is related to recombination

22. With which protein(s) is a condensed eukaryotic chromosome NOT known to be associated? 1. core histones H2A, H2B, H3, and H4   2.histone H1   3.SMC proteins   4.topoisomerase I   5.topoisomerase II

Please atleast answer this question

18. This question refers to the following schematic diagram of two normal chromosomes and five aberrant forms (A through E) of those chromosomes. (Circles represent centromeres and letters represent genetic loci). Which of the aberrant forms represents duplication? Normal Chromosomes (A) (B) | (D) (E)

the inversion in question 2 is a pericentric inversion
