isPermaLink="false">http://biology-today.com/?p=1957</guid> <description><![CDATA[An interesting mode of infection and transmission of viruses was found in bacterial system. Normally a bacterium infected with bacteriophage would lyse after some time and release a progeny of bacteriophages. In many experiments it was seen that the bacterium does not lyse and happily undergoes division. Analysis of such bacteria showed that the phage [...]]]></description> <wfw:commentRss>http://biology-today.com/cell-biology/infection-in-bacteria-by-lysogenic-bacteriophages/feed/</wfw:commentRss> <slash:comments>0</slash:comments> </item> <item><title>Mode of viral infection</title><link>http://biology-today.com/cell-biology/mode-of-viral-infection/</link> <comments>http://biology-today.com/cell-biology/mode-of-viral-infection/#comments</comments> <pubDate>Fri, 13 Jan 2012 16:49:41 +0000</pubDate> <dc:creator>Zoology</dc:creator> <category><![CDATA[Cell Biology]]></category> <category><![CDATA[Bacteria]]></category> <category><![CDATA[Bacteriophages]]></category> <category><![CDATA[cell biology]]></category> <category><![CDATA[viral infection]]></category> <category><![CDATA[virus DNA]]></category><guid
isPermaLink="false">http://biology-today.com/?p=1955</guid> <description><![CDATA[If a colony of bacteria is infected with bacteriophages, the bacteria undergo chance collision and ultimately the phages attach to the bacterial cell wall through tail fibres. The DNA of the phage is injected into the host cell by dissolving the cell wall at the point of attachment, and the protein shell remains outside.

The whole world today is so much shaken up with this word that it has become a strong belief that this is "the field, which will give solution to our "any problem."

These direct the synthesis of the mRNA and govern the sequence of amino acids in a protein molecule. Each structural gene might produce a particular kind of protein or all structural genes might regulate the production of a single protein.

This DNA, coming from the organelle responsible for cellular respiration, possesses no link with nuclear DNA. While less discriminating in the analysis of STRs than nuclear DNA, the characterization of mitochondrial DNA represents [...]]]></description> <wfw:commentRss>http://biology-today.com/cell-biology/some-aspects-of-mitochondrial-dna/feed/</wfw:commentRss> <slash:comments>0</slash:comments> </item> <item><title>Describe the clover leaf model of tRNA</title><link>http://biology-today.com/cell-biology/describe-the-clover-leaf-model-of-trna/</link> <comments>http://biology-today.com/cell-biology/describe-the-clover-leaf-model-of-trna/#comments</comments> <pubDate>Thu, 03 Feb 2011 04:36:36 +0000</pubDate> <dc:creator>Zoology</dc:creator> <category><![CDATA[Cell Biology]]></category> <category><![CDATA[Clover Leaf Model of tRNA]]></category> <category><![CDATA[tRNA structure]]></category><guid

The DNA structure mentioned above is uniform in all organisms, whether it is man or virus. At the same time it is also true that DNA is the genetic material that decides the characters of individual organisms.
