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?
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...
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...
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...
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...
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:...
in their appearance and expression. This is due to the selective expression and repression of genes in that particular cell. That’s why your heart cells look very different from the cells that make up your eye. The mechanism of this differentiation through gene regulation is termed epigenetics....

What are genetic imprinting mutations? What kind of mutation causes trisomy 21? Are germline mutations expressed in every cell? What chromosome has the genetic mutation for diabetes? What is a point mutation? What is the least common genetic mutation type?
What is genetic code and what is its role in directing the functions of the cell? Answer of the following question. What is the role of telomerase in DNA replication? What is DNA? What is the structure and function of DNA? What is DNA polymerase? What function does it have?
