Q:

Is Tay Sachs disease dominant or recessive?

A:

According to WebMD, Tay Sachs disease is an autosomal recessive disease, meaning both parents need to have a copy of the mutated gene in order to pass it onto their offspring. Tay Sachs disease is a very rare genetic disorder, usually affecting those of Ashkenazi Jewish heritage.

Tay Sachs disease gradually destroys nerve cells in the brain and spinal cord, according to the National Library of Medicine. As more neurons are destroyed, motor functions are affected and eventually deteriorate entirely in the form of paralysis. Intellectual development is also stunted. The most common form of this disease begins to affect children as young as 3 to 6 months of age.

    What is the "Law of Segregation" in biology?

    A:

    In biology, the law of segregation explains how the offspring of parents with similar characteristics sometimes have offspring with a different characteristic. It is one of the rules regarding genetics discovered by Gregor Mendel in the 1860s. According to this law, the two alleles, which form a gene, separate during the formation of the reproductive cells and recombine as the two parent cells join, determining the genetics of an offspring.

    What is antisense RNA technology?

    A:

    Antisense RNA technology is a treatment for genetic disorders or infections that involves turning off the gene causing the disease. This is done by synthesizing a strand of DNA or RNA that binds to the mRNA produced by the gene and deactivates it. Antisense RNA technology has been largely unsuccessful due to its toxicity, problems with delivery methods, instability, manufacturing cost, administration and circulation time.

  • Q:

    Do non-pathogenic bacteria cause disease?

    A:

    According to the Merriam-Webster Dictionary, "non-pathogenic" means that an organism does not cause disease, so non-pathogenic bacteria do not cause illness. Some bacteria are helpful within their environments.
