What is the purpose of dependentAssembly tag for System.Web.Extensions namesapce?

[Bala]

Hi Experts,

   What is the purpose of below tag [ in web.config]  in  rad version 2010.2.713.35  application?
   Is this required tag  in 2010.2.713.35  application?
   Is this specific to rad controls or ASP.NET Ajax 3.5?
   Shall I run my web application [With rad controls v2010.2.713.35 and Ajax 3.5 ]  without this tag?

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35"/>
                <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
            </dependentAssembly>
            <dependentAssembly>
                <assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31bf3856ad364e35"/>
                <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
            </dependentAssembly>
        </assemblyBinding>

Please any one help me.
Thanks in advance.
