Bacterial transformation and bacteriophage labeling experiments proved that dna was the hereditary material in bacteria and in dna-containing viruses. some viruses do not contain dna but have rna inside the phage particle. an example is the tobacco mosaic virus (tmv) that infects tobacco plants, causing lesions in the leaves. two different variants of t mv exist that have different forms of a particular protein in the virus particle that can be distinguished. it is possible to reconstitute t mv in vitro (in the test tube) by mixing purified proteins and rna. the reconstituted virus can then be used to infect the host plant cells and produce a new generation of viruses. design an experiment to show that rna acts as the hereditary material in tmv.

Mix RNA from virus type I with the protein from virus type II to reconstitute a hybrid virus. In a parallel experiment, mix protein from virus type I with the RNA from virus type II. After that infect the cells with each of these reconstituted hybrid viruses distinctly, and assess the protein in the progeny viruses, which originates from each of the infections.  

One will see that the progeny viruses in each case exhibit the protein, which matches the type of RNA in the parent hybrid virus. The protein in the progeny did not match with the protein in the parent hybrid virus.  

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.
