Mitochondria and plastids have their own DNA (genetic material). What is their fate during nuclear division like Mitosis

Who proved that DNA is genetic material ? What is the organism they worked on?

A few statements describing certain features of production are given below (I) gametic fusion takes place (II) transfer of genetic material takes place (III) reduction division takes place (IV) progeny have resemblance with parents How many of the above statements are true for asexual and sexual reproduction

Recall the experiments done by Frederick Griffith. Where DNA was speculated to be the genetic material. If RNA, instead of DNA was the genetic material, would the heat killed strain of pneumococcus have transformed the R - strain into virulent strain ? Explain ?

Mitosis result in producing two cells which are similar to each other. What would be the consequence if each of the following irregularities occurs during Mitiosis ? a) Nuclear membrance fails to disintegrate b) Duplication of DNA does not occurs. c) Centromeres do not divide d) Cytokinesis does not occur.

A parallel plate capacitor is to be desigined with a voltage rating 1kV, using a material of dielectric constant 3 and dielectric strength about 10^7 Vm^(-1) (Dielectric strength is the maximum electric field a material can tolerate without breakdown, i.e., without starting to conduct electricity through partical ionisation. ) For safety, we should like the field never to exceed, say 10% of the dielectric strength. What minimum area of the plates is required to have a capacitance of 50 pF?

Can you name the two organelles you have studied that contain their own genetic material?
