Concept explainers
a.
To determine:
Whether a male inherits an X chromosome from his mother or his father.
Introduction:
Studying human inheritance patterns have given many insights into how genetic disorders arise and progress.
b.
To determine:
The types of gametes that can be produced by a male with respect to X-linked alleles.
Introduction:
Several genetic disorders are associated with alleles on the X chromosome. Almost all of X-linked disorders are inherited in a recessive pattern.
c.
To determine:
The kind of gametes that can be produced by a female which is homozygous for an X-linked allele.
Introduction:
The examples of X-linked recessive disorder are Duchenne muscular dystrophy, hemophilia A, red-green color blindness, and others.
d.
To determine:
The kind of gametes that can be produced by a female which is heterozygous for an X-linked allele.
Introduction:
The human X chromosome carries about 2, 000 genes, which is almost 10 percent of the total genome.

- please fill in the empty sports, thank you!arrow_forwardIn one paragraph show how atoms and they're structure are related to the structure of dna and proteins. Talk about what atoms are. what they're made of, why chemical bonding is important to DNA?arrow_forwardWhat are the structure and properties of atoms and chemical bonds (especially how they relate to DNA and proteins).arrow_forward
- The Sentinel Cell: Nature’s Answer to Cancer?arrow_forwardMolecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forward
- Molecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. Although the gene was successfully transcribed and translated, it produced a different protein than it produced in the eukaryotic cell. What is the most likely explanation?arrow_forwardMolecular Biology LIST three characteristics of origins of replicationarrow_forwardMolecular Biology Question Please help. Thank you For E coli DNA polymerase III, give the structure and function of the b-clamp sub-complex. Describe how the structure of this sub-complex is important for it’s function.arrow_forward
