Replication in Eukaryotes

Replication in Eukaryotes

In eukaryotic cells, DNA replication is highly conserved and tightly regulated. Multiple linear chromosomes must be duplicated with high fidelity before cell division, so there are many proteins that fulfill specialized roles in the replication process. Replication occurs in three phases: initiation, elongation, and termination, and ends with two complete sets of chromosomes in the nucleus.
Many Proteins Orchestrate Replication at the Origin
Eukaryotic replication follows many of the same...

Longitudinal Research

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Area of Science:

Philosophy of Technology
Artificial Intelligence Ethics
Digital Humanities

Background:

Ongoing ethical debates surround biological lifespan extension technologies.
Growing interest in artificial intelligence (AI) for creating digital twins of individuals using large language models.
Exploration of non-biological pathways for extending human existence.

Purpose of the Study:

To investigate whether digital doppelgangers can offer a form of person extension independent of biological continuity.
To examine if digital doppelgangers can achieve the aims of person-span extension.
To consider the implications of digital doppelgangers for relational accounts of personhood.

Main Methods:

Philosophical analysis of consciousness and personal identity theories.
Examination of relational theories of personhood.
Conceptual exploration of digital doppelgangers as a form of person extension.

Main Results:

Digital doppelgangers may fulfill some aims of person-span extension, even if not literal extensions of personhood.
They might extend personhood in a relational sense or secure relational goods.
The concept offers a novel perspective on life extension debates.

Conclusions:

Digital doppelgangers present a potential avenue for person extension not reliant on biological continuity.
Further research into digital doppelgangers is relevant to the ethics of human lifespan extension.
These entities may offer a way to achieve aspects of extended personhood and relationships.
