Question

Heterozygosity for which of the following chromosome rearrangements will produce a dicentric bridge as a result of crossover in meiosis? See Section 10.5 (Page 381) Large duplication Paracentric inversion Reciprocal translocation Pericentric inversion Submit Request Answer

Answer 1

Paracentric inversion or arrangements will produce a dicentric bridge as a result of Wyobb over in mei'o 515 mence, the correct option is (6) All the other options like clarge duplication and creciprocal translocation do not produce a dicentare 3 The Reciprocal balanced branslocation results of a defravalent structure in the formation at synaptis. n Hence the loverect option is o results in the 3 Robertsonian translocation fusion of two non homologous chromosomes to produce a larger chromosomes and a net reduction i un chromosome number. n option is o Hence the correct Ž The solenoid structures is the term used to describe 30nm-fibere devel of chromosome condensations. The solenoid structure of chromatin is a model for the Bonm-fibre Structure. Lonni now Hence the correct option is eruetur. There are 5 types of histone proteins found in Chromatis Hi (or HS), HRA, H&B, Hz and Hu 'Hence, the correct option is (b). Hi and its homologaus protein is involve in higher lander Structure of chromatin.
