答案:Mitochondria are often referred to as the "powerhouses" of the cell because they generate most of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy. They are unique among cellular organelles because they have their own mitochondrial DNA and ...
Describe the structural levels of DNA and RNA. Briefly describe what you know about the structure of DNA and how DNA is packaged in a cell. Describe the basic structure of DNA. Discuss why DNA is often called a "protein recipe".
Describe the structure and function of DNA. Describe the role nucleotides play in DNA. Describe the significance of the order in which nucleotides are formed. Explain the general structure of DNA. A DNA molecule is made of four types of nucleotides - Adenine, Guanine, Thymine, and Cytosine. a...
Here we tested the possible role of DNA methylation in mediating long-term induction of epileptiform activity by transient kainic acid exposure using in vitro and in vivo rodent models. We analyzed changes in the gria2 gene, which encodes for the GluA2 subunit of the ionotropic glutamate, alpha...
Describe the properties of water while applying the role of hydrogen bonding. Describe hydrogen bonding and discuss its importance. How do molecular dipole moments help distinguish between (E)- and (Z)-1,2-dichloroethene? What is the main purpose of EDTA in DNA extraction?
Hydrogen-bonding plays a fundamental role in the structure, function, and dynamics of various chemical and biological systems. Understanding the physical n... SM Kashid,S Bagchi - 《Journal of Physical Chemistry Letters》 被引量: 0发表: 2014年 Natural energy decomposition analysis: An energy parti...
2. minichromosomes are applied widely to study initiation mechanism of dna replication in prokaryotes because the phages and plasmids are not good models. ( ) 3. transposons (tn) or transposable elements are small dna sequences that can move to virtually any position in a cell genome. ( ) ...

Describe the structural and chemical features which contribute to the remarkable mechanical properties of the stomatopod dactyl club. Mechanical Properties: Mechanical properties are a material's physical and chemical properties that determine how it behaves when ...
Scientists from the University of Leicester have for the first time created a detailed image of a toxin - called pneumolysin - associated with deadly infections such as bacterial pneumonia, meningitis and septicaemia.
