Question Number Answer Mark 1 (a)(i) The only correct answer is C metaphase A is incorrect as centromeres and spindle fibred do not join in anaphase B is incorrect as centromeres and spindle fibres do not join in interphase D is incorrect as centromeres and spindle fibres do not join in telophase [1] Question Number Answer Mark 1 (a)(ii) The only correct answer is C prophase A is incorrect as the nuclear envelope does not start to break down in interphase B is incorrect as the nuclear...

NSG 530 STUDY GUIDE Patho Quiz 1 Graded A+. STUDY GUIDE FOR QUIZ #1 Advanced Pathophysiology Study the process of meiosis – specifically what occurs when homologous chromosomes fail to separate Human cell can be categorized into gametes (Sperm & egg cells) and somatic cells, which include all cells other than gametes. Each somatic cell nucleus has 46 chromosomes in 23 pairs. These are diploid cells, and the individual’s father and mother each donate on chromosome per pair. New somatic...

The two new daughter cells will be haploid, but the DNA they contain is still replicated. The homologous chromosomes have separated and are ready to start the second division, but they have not yet begun the second round of division. Which stage of the cell cycle is this cell in? Telophase I Homologous pairs of chromosomes have separated into two cells. Sister chromatids in each cell have not yet lined up in the middle of the cell. Which stage of the cell cycle is this? Prophase I...

What does the process of meiosis result in? - -A reduction in the chromosome number Why is crossing-over one of the most important events in meiosis? - -It produces new combinations of alleles on chromosomes. Which mode of inheritance describes a condition that exclusively affects males? - -Y-linked A man with disease X and a woman without disease X have five sons and five daughters. All of their daughters inherit the disease, while none of the sons do.Which mode of inheritance is described...

Adaptation- - correct answersThe adjustment or changes in behavior, physiology, and structure of an organism to become more suited to an environment. Aerobic- - correct answersA process that requires oxygen. Allele -An alternative form of a gene. An example would be genes that encode eye color—some encode blue eyes (one allele), while others encode brown, green, or hazel eye colors (other alleles). - correct answers amino acids - - correct answersA small organic molecule with the stru...

What modification neutralizes the charges on histones and looses up the interactions between histones and DNA? - Answer- ACETYLATION Two types of post-transcriptional modifications that take place in the mRNA of eukaryotes - Answer- the addition of a CAP at the 5' end of the transcript and the addition of a POLY A sequence at the 3' end of the message Nucleic acid blotting is widely used in recombinant DNA technology. In a Southern blot one generally - Answer- Hybridizes filter-bound DNA...
