Building the Singapore Mitochondrial DNA (mtDNA) Tree
Common Ancestors:
Every person has two parents, four grandparents, eight great-grandparents,
and so forth. At each generation, the number of ancestors doubles. At some
point in the past, we share common ancestors and this can mean that people
around the world are related to varying degrees.
Constructing the Singapore mtDNA
Tree: To build this mtDNA tree, we are collecting mtDNA samples
from people all over Singapore. The mtDNA samples obtained are assigned a
code that identifies the information without compromising the
confidentiality of the participants. Laboratory techniques are then applied
to extract and analyze the participants' mtDNA samples. Thereafter, the
fascinating process of correlating genetic information can be done.
DNA (Deoxyribonucleic Acid):
The human DNA contains genetic information necessary for life and
hereditary traits. Genetic material can also be found inside the
mitochondria, which are the energy-producing organelles found in the
cytoplasm of the cell.
DNA and Genealogy:
Molecular genealogy is a relatively new method of research for complementing
traditional genealogical techniques. DNA is transmitted from one generation
to the next. Some parts are passed almost unchanged and create a connection
between generations. Such a phenomenon is useful in the study of ancestry.
Since all people inherited genetic
material from their ancestors, very distantly related individuals can share
portions of this information. As such, the greater the amount of shared
genetic information can indicate the closer the relative. Thus, although
the entire DNA sequence of an individual is unique to that individual,
similar genetic information can be found among those that descend from
common ancestors.
Mitochondrial DNA Tree Workshop
This is a 3-session workshop conducted
by NBL comprising educational presentations complemented by hands-on
work. This is a wholesome programme in that it not only educates, but
also takes the participants through a journey of discovery and learning.
  |
This workshop aims to:
-
provide insights into the basics of life
sciences and bioinformatics including their relevancy to our lives
-
build an awareness of the role played by
mitochondrial DNA in our lives
-
reveal how mitochondrial DNA connects us to
the people who have positively contributed to Singapore's history,
e.g. Lim Bo Seng, Tan Kah Kee, Syed Mohammed bin Ahmed Alsagoff, P
Govindasamy Pillai, Benjamin Henry Sheares, etc
-
create an awareness and share knowledge about Singapore's rich cultural and historical heritage with respect to
biological diversity
-
form experiences that can connect the public
to Singapore's rich history and heritage
-
build a simple mitochondrial DNA tree and
thereafter, discover and understand the tree's meaning and relationships
with respect to the participants
Participants will get to experience
first hand on how to extract, replicate your own DNA from cheek cells in
a laboratory environment and eventually get to find out part of their
mitochondrial DNA sequence. This will provide participants with an
introductory insight into the basics of life sciences. |
|

In the final session of the workshop, participants
will move from the "wet" laboratory to the "dry" (computing) laboratory
where they will learn about bioinformatics (basics), get to build your
very own mitochondrial DNA tree and along the way, discover many
interesting things about yourself and the people around you.
