Question
Chapter 11, Problem 23A
Summary Introduction
To analyze:
A micrograph of stained chromosomes.
Introduction:
Micrograph: It is a digital image or photograph of any specimen taken through a microscope to get a magnified image.
Chromosome: It is the thread-like structure made up of protein and DNA, which is present in the nucleus of the cell.
Expert Solution & Answer
Explanation of Solution
A micrograph of stained chromosomes is called Karyotype, where pairs of homologous chromosomes are arranged in decreasing size.
A karyotype test is done to know the size, shape, and number of chromosomes in any organism.
Karyotypes are prepared from mitotic cells.
Conclusion
The karyotype of humans has 23pairs of chromosomes with 22 pairs of homologous chromosomes and one pair of nonmatching sex chromosomes.

- "One of the symmetry breaking events in mouse gastrulation requires the amplification of Nodal on the side of the embryo opposite to the Anterior Visceral Endoderm (AVE). Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE. 1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site 4. BMP4 on outside-> nodal Are all of these occuring opposite to AVE?arrow_forwardIf four babies are born on a given day What is the chance all four will be girls?

- Plekhg5 functions in bottle cell formation, and Shroom3 functions in neural plate closure, yet the phenotype of injecting mRNA of each into the animal pole of a fertilized egg is very similar. What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forwardWhat are some medical issues or health trends that may have a direct link to the idea of keeping fat out of diets?arrow_forwardwhat did charles darwin do in sciencearrow_forward
