Describe one similarity between DNA and RNA. How are the structures of RNA and DNA similar? How are chromatin, chromosomes, and DNA related? If all cells contain the same DNA, how do cells differentiate? How are genetic characteristics linked with DNA structure?
(a)All organisms need to control the expression of their DNA in the process of growth and development. Even bacteri a need to do so. Using the example of E. coli, compare and contrast the control of gene expression in a bacteri a with the similar processes in a typical eukaryotic cell...
Protein-DNA interactions play vital roles in many cellular processes. It is not clear whether the recognition of same protein-DNA complexes in different organisms is similar or different. In this work, we have analyzed the similarities and variations in interactions and interacting patterns in a ...

Similar to all known Hsf coding genes of other organisms, the DBD of plant Hsfs is encoded in 2 parts separated by the only intron, which is inserted immediately upstream of the coding part for the H2-T-H3 DNA binding motif. The position of the intron is identical in all cases, but th...
We conclude that asexuals are expected to display discrete clusters similar to those found in sexual organisms. Whether sexuals or asexuals display stronger clustering depends on a number of factors, but in at least some scenarios asexuals should display a stronger pattern. Confounding factors aside,...

Following our previous characterization of a gene, masc1 from , encoding the 'de novo' C5-DNA-(MTase), we report here the identification of a second MTase gene, masc2. The deduced sequence of Masc2 is similar to previously identified eukaryotic MTases and distinct from Masc1 by having a ...

In general, the procedures for the transformation of different organisms are similar, but each organism has its own conditions for optimal transformation efficiency. Nowadays Agrobacterium-mediated transformation is the method of choice for the transformation of various fungi as transformation efficiencies ...
