BMED 1207 Fundamental of
biomedical questions and
answers
branches of biomedical engineering - answer
biomaterials,biomechanics,diagnostic imaging and therapeutic
devices,computational medicine, signal and image analysis and biomolecular
cell and tissue engineering
Electronic / bio circuit analogy - answer Computers-cells
modules -pathways
Gates- biochemical reactions
physical layers-proteins, genes
Synthetic biology - answer Is an interdiscliplinary branch of biology and
engineering. It aims to design and construct biological parts, devices and
systems.
what is high-throughput profiling ? - answer a microarray to measure gene
expression
networks in biology - answer gene co-expression networks( transcript
transcript association networks
Gene regulatory networks (DNA protein interaction networks)
protein protein interaction networks
signalling network
metabolic networks
neuronal networks
, genetic interaction - answer
how many different types of nitrogenous bases - answer
What is a primer? - answer A short segment of DNA that acts as the starting
point for a new strand
the experiment that DNA is the genetic material - answer Experiment: The
experiment began with the culturing of viruses in two types of medium. One
set of viruses (A) was cultured in a medium of radioactive phosphorus
whereas another set (B) was cultured in a medium of radioactive sulfur. They
observed that the first set of viruses (A) consisted of radioactive DNA but not
radioactive proteins. This is because DNA is a phosphorus-based compound
while protein is not. The latter set of viruses (B) consisted of radioactive
protein but not radioactive DNA.
The host for infection was E.coli bacteria. The viruses were allowed to infect
bacteria by removing the viral coats through a number of blending and
centrifugation.
Observation: E.coli bacteria which were infected by radioactive DNA viruses
(A) were radioactive but the ones that were infected by radioactive protein
viruses (B) were non-radioactive.
Conclusion: Resultant radioactive and non-radioactive bacteria infer that the
viruses that had radioactive DNA transferred their DNA to the bacteria but
viruses that had radioactive protein didn't get transferred to the bacteria.
Hence, DNA is the genetic material and not the protein.
the attributes of DNA as genetic materials - answer its stability and
heritability
1- Between the complementary base pairs, hydrogen bonds connect the two
strands of the helix. There are 3 H bonds between Guanine and Cytosine and
2 between Adenine and Thymine. there are hydrogen bonds between the
bases and surrounding water molecules, and this combined with the even
stronger phosphodiester bonds in the sugar phosphate backbone make DNA
very stable.
