What is a template strand in DNA replication? What is a DNA polymerase? What does it do or what is it involved in? What is the relationship between a cell's genome and its proteome? What does a nucleotide in DNA consist of? What is a read (biology)? What is a reference genome? Explore our homework questions and...
If mutation occurs causing transcription of a gene to occur on both strands of the DNA in the same cell, what affect would you expect that to have on the production of protein for the gene? What is bidirectional DNA replication? What is a plasmid? How is a plasmid used in gene splicing...
Imprinting center defect:Genes in PWCR on the chromosome that originated from the mother are inactivated due to a process known as “imprinting,” which affects whether the cell can “read” a gene in five percent of cases. Most cases of PWS are not inherited, particularly those caused by a...
A Mendelian trait is one that is controlled by a single locus in an inheritance pattern. In such cases, a mutation in a single gene can cause a disease that is inherited according to Mendel's principles. ... Examples includesickle-cell anemia, Tay–Sachs disease, cystic fibrosis and xeroder...

The most challenging medical diagnosis I have been introduced to is isodicentric chromosome 15 syndrome. This syndrome occurs in about 1 in 30,000 newborns and is a result from having an abnormal extra chromosome in each cell. The chromosome has mirror-image segments instead of a different segme...
As such, the relationship between the T cell and self is dynamic and evolves over time. Here we discuss the role of the self-immunopeptidome in establishing naive T cell heterogeneity throughout a T cell’s life and ask what the distinct roles of self-mediated thymic imprinting versus ...
There are challenges in detecting microdeletions and microduplications, de novo variants, and imprinting disorders. Another issue is the detection of mosaicism during PGT-A. While the clinical utility of PGT-M and PGT-SR are established, the best use of PGT-A in IVF is not as clear. Cost:...
What is the importance of blood plasma being isotonic to the cytosine of a cell? What is the importance of emulsification in lipid digestion? What is melanin and why is it important? What is the importance of knowing vasocongestion and myotonia?
