Somatic cell nuclear transfer
(
SCNT
). A technique in which the nucleus
of a somatic (body) cell is transferred into the cytoplasm of an enucleated
egg: an egg with a removed nucleus. Once inside the egg, the somatic
nucleus is reprogrammed into a fertilized egg nucleus by egg cytoplasmic
factors. Eggs develop to the blastocyst stage, where the inner cell mass of
the blastocyst can be cultured with
embryonic stem cells
(
ESCs
). This
process can lead to zygotes, as well as full-fledged organisms. Mouse,
monkey, and human ESCs were generated using SCNT. ESCs in humans
have potential for both medical and research applications. SCNT has been
used to clone a variety of animals, including sheep, cows, pigs, mice, and
monkeys. (Stocum, 2016)
The simplified process of how a cloned cell is created:
A somatic cell is taken from the donor organism, its nucleus is removed. It is then
placed in an enucleated egg; this egg is then stimulated to divide. The egg is then
transferred into a surrogate mother, and it eventually develops into an exact
genetic copy of its donor animal. This is how we created the first cloned animal,
Dolly the sheep (Roslin Institute, 2019).
This technology has great potential, moving us towards a healthier world, dealing
with medical issues, such as:
Creating new organs/tissues that are genetically identical to the recipient: this would
eliminate the need for immunosuppressive medicines, as well as a need for black market
organ harvesting.
The development of new medical procedures that would combat and potentially reverse
Alzheimer’s: by using stem cells and bio-identical cells to help the brain regenerate
function (Liu et al., 2020).
Aiding in the preservation of endangered species; could you imagine a world where we
had the Thylacine- Tasmanian Tiger?
Helping the agricultural industry become more sustainable through massive cloning of
animals, created for specific purposes such as milk production or meat.
Some of the potential risks of cloning include:
The increased risk of birth defects in cloned animals, which could be caused by the
reprogramming of the donor cell nucleus or by the epigenetic changes that occur during
cloning.
The incentive of commercializing the technology would be massive. Creating a market
where only then rich would benefit from its potential.
There could be a risk of people in power using this technology to push eugenic ideals for
a “pure” race or human beings.
The ethical concerns surrounding the cloning of humans, such as the potential for
creating designer babies, or even cloning oneself. This raises the question of what
makes a human, a human. We cannot ignore the fact that genetic material does not
dictate our experience in this world, hence our personalities would be unique from

Article:
Biomimetic Engineering of Nanodelivery Systems: Artificial Viruses in the Making
In an effort to engineer the next generation of nanoscale vectors, scientists have moved from using inorganic components aimed at obtaining inert structures to utilizing biological building blocks that are able to convey additional functionalities to the resulting construct. To cope with the complexity of the body and to evade the multiple layers of defense that tissues and organs have, it is critical to rely on the ability of certain materials to interact with, rather than to eschew, the biology of our body. Every NP system conceived to date faces one common fate: whether injected,…

Viruses, although not considered to be alive, attack host cells and cause disease. The attack of a host cell is necessary for the virus
to survive for all of the reasons listed EXCEPT one. That is
they cannot synthesize proteins becayse they lack ribosomes and must use
the ribosomes of their host cells to translate viral messenger RNA into new Eliminate
proteins.
A)
they cannot produce or store energy in the form of ATP and have to get
their energy from the host cell.
B)
they parasitize the host cell for basic molecules like amino acids,
nucleotides, and lipids.
D)
they lack DNA/RNA so they must use the DNA of the host cell.

Practice Case study p. 224 part: Tuberculosis (TB) in indigenous populations.
Lily was a recent science graduate of the University of Alberta and was 11 months into her 12 -
month Master of Science in Global Health degree, at Dalhousie University. This relatively new
program was created to provide the multidisciplinary training required of scientists working to
meet the complex challenges of global public health issues. The University had partnered with the
National Collaborating Centre for Indigenous Health (NCCIH) and that was why Lily now found
herself doing her Global Health Field Practicum in the Northern Territories, working on a study
of drug resistant TB infections among Innuit communities.
The different communities included in her research were close to 7000 individuals, with multiple
diagnosed cases of TB. And while she was grateful that drug-resistant TB in Canada remained
below the global average (Public Health Agency of Canada, 2019), she was cognizant of the
