NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT
Step-by-Step Solution:1. Understanding the Question: The question asks at which stage homologous chromosomes begin to separate during meiosis.2. Identifying the Stages of Prophase I: Pro
What is the process in which homologous chromosomes wrap around? Homologous chromosomes separate during What is the difference between homologous chromosomes and chromatid? How many homologous chromosomes do humans have? How do the two members of a pair of homologous chromosomes differ from each other...
In metaphase 1 of meiosis, the homologous chromosomes line up side by side along the equator so that crossing over can occur between the homologous pairs and the homologous chromosomes can be pulled to opposite poles during anaphase 1. In mit...
Similarly, if the individual homologues don’t separate into their respective sister chromatids during meiosis II, the resulting daughter cells will also have either too many or too few chromosomes, conditions called trisomy (3 chromosomes) and monosomy (one chromosome). For the most part, the ac...
Normally, bacterial cells are genetically haploid, because they lack mechanisms to preserve diploidy and therefore segregate homologous chromosomes into separate cells. To detect homologous recombination in bacteria, cells are used that carry additional DNA segments homologous to the resident chromosome. Such...
JMs can be resolved to produce chromosomes that have, or have not, undergone a reciprocal exchange of genetic material (crossing-over) [13] (Fig. 1). Mitotic recombination differs from meiotic recombination in several aspects. Recombination is pre-programmed and essential during meiosis, but ...
Crossover between non-sister chromatids results in new combinations of parental alleles on the crossover chromosomes. DNA helicase An enzyme that uses the energy from ATP hydrolysis to separate the two DNA strands in a double helix. Post-replication DNA repair A process that repairs gaps on ...
We determined the translocation region of chromosomes in patient with t(3;5)(q24;q13) balanced chromosomal translocation by shallow whole-genome sequencing, which is helpful to pinpoint the chromosomal break point. We showed that SCS can physically separate and independently sequence three copies of...
Homologous recombination-mediated DNA repair is essential for maintaining genome integrity. It is a multi-step process that involves resection of DNA ends, strand invasion, DNA synthesis and/or DNA end ligation, and finally, the processing of recombination intermediates such as Holliday junctions or ...
