How many chromosomes are there in humans after S-phase? How is the genetic code analogous to the letters of the alphabet? What is short tandem repeat and how does it affect population genetics? Summarize the process of DNA replication. ...
Under this model, chromosomes pair at special regions whose interaction is mediated by some molecules which diffuse in cells' nuclei and can bind them. Concentration of these molecules acts as a switch for pairing: at low concentrations chromosomes move independently one from another whereas if ...
Answer and Explanation: Duplicated chromosomes are called homologous chromosomes. These are the structures which form in meiosis, after S phase when the DNA has replicated...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our...
- Importantly, sister chromatids remain attached at their centromeres during this phase. 4. Evaluating Other Phases: - Telophase I: This is the phase after Anaphase I where the chromosomes reach the poles and the cell begins to divide. The separation of homologous chromosomes has already occurred...
Resolution of this DNA intermediate can produce crossover recombinants that harbour a reciprocal exchange of the arms of the recombining chromosomes. Crossovers are crucial for chromosome segregation at meiosis I, but their formation is suppressed in mitotic cells because of an inherent risk of ...
A PCR product is detected only in cells participating in the repair process since the primers are complementary to different chromosomes. Polymerized invasion intermediates can be seen very early after DSB induction and peak approximately half an hour after detection of the DSB. This indicates that ...
have to be resolved by pairs of strand cuts (marked either ‘1’ or ‘2’). Resolution of both junctions in the same sense (1–1 or 2–2) regenerates parental chromosomes, while resolution of the two junctions in the opposite sense (1–2 or 2–1) produces recombinant chromosomes. ...
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...
h,i, HeLa radial chromosomes (h) and chromatid-type fusions (i) in the first mitosis post 14 Gy IR (mean n = 2, except 0 Gy control siRNA (n = 4), N = 50 metaphases per replicate, two-sided Fisher’s exact test of N). The control siRNA are the 0 and 36...
During meiosis II: a. homologous chromosomes align and are joined through synapsis. b. non-sister chromatids of homologous chromosomes recombine. c. sister chromatids separate. d. both a and b. e. all of the above. During meiosis I: a. homologous chromosomes align and are j...
