Ma'am, can't the attacking bacteriophage contain methyl groups making the restriction enzymes ineffective?
Isha Singh

Hi Sharan, Methylation is not a very common phenomenon in Viruses. Having said that, there can be multiple other reasons as to why the bacteriophage does not exhibit the protective methylation. I’ll explain some of those: 1. Methylation generally occurs, at Cytosine residues present as a part of specific sites called CpG sites (contain Cytosine residue followed by a Guanine in 5’ to 3’ direction) within the genome. In viruses, either due to evolutionary mechanisms or due to mutation of CpG intp TpGs, there is a substantial decrease in the presence of these CpG sites, resulting in lesser or no methylation. 2. The Bacteria specifically methylates the recognition sequences of its Restriction Enzymes. This kind of highly specified methylation might be absent in the viral genome, making it susceptible towards the action of those REs. 3. Methylation is carried out by specific enzymes, which might be absent in the Viral body. Thus, the viral genome shows no methylation. Let me know if this answers your question!

Gee..Thanks a lot ma'am! I've understood properly now. Keep up the remarkable work ma'am. Good day!
mam what is the meaning of this line - diffusion in solids rather than of solids is more likely..

very nice mam
didi ncert ke yek line ka matlab nahi samja 1.diffusion is obvious in gases and liquids 2.diffusion in solids rather than of solids is more likely 2nd point nahi samja.

Diffusion non living surface me bhi hoti h. Jaise pani me dye ka dissolve hona, perfume bottle se spray hona

Aur 2nd line ka mtlb h ki diffusion solid se solid me zada achhe se hoti h , kisi aur medium ki apeksha

  2. Target Audience NEET,NET,AIIMS,UPSC UPPSC,LT GRADE, SSC,UG PG COURSES


  3. Important Terminologies in Plant Physiology By-Juhi S.Mishra


  4. This is Juhi Mishra * M.Sc.in Botany(Gold Medalist) 7 years of Teaching Experience CET, DCA & B.Ed in Biology


  5. Plant physiology. Definition. Plant physiology is a sub-discipline of botany concerned with the physical, chemical and biological functioning of plants.


  6. POINTS TO REMEMBER Translocation: Transport of substances in plants over longer distances through the vascular tissue (Xylem and Phloem) is called translocation.


  7. Means of transport: The transport of material into and out of the cells is carried out by a number of methods. These are diffusion, facilitated diffusion and active transport.


  8. Diffusion : Diffusion occurs from region of higher concentration to region of lower concentration across the permeable membrane. It is passive and slow process. No energy expenditure takes place



  9. Diffusion Particle net movement from; a region of HIGH concentration to a region of LOW concentration Movement of Particles to LowConcentration High Concentration Diffused Throughout Equilibrium
