could we find an organism where functional RNA or protein molecules were copied directly to pass on to offspring?

Solutions

Expert Solution

Answer:

Viruses are used as organisms where functional RNA molecules were copied directly to pass on to offspring. We cannot find an organism where functional protein molecules were copied directly to pass on to offspring.

Explanation:

Genes are functional unit of an organism which is copied to RNA and translated into proteins. Proteins catalyzes biological function of an organism.

DNA was the transforming factor
Avery concluded that DNA was the transforming factor that causes transformation.

Therefore, in every organism (except viruses in which genetic material can be RNA or DNA) DNA is used as genetic material and copied into RNA by transcription. Proteins are made by RNA by translation process. Genes are made of DNA are used as hereditary material to be passed into offsprings.

Positive-sense ssRNA viruses used mRNA directly and translate it into a protein. The viral genomic RNA is complement of the mRNA and can be directly copied to a + strand before translation and inserted into host cell.

Look at situation where there are 2 molecules of the same protein, which means same primary sequence. In addition they fold at the same time in the same funnel. Each protein, which is represented by a marble, is predicted to take a special path as it moves down the funnel during the folding process. While it folds, it is possible that the two proteins collide on the way down the funnel, and as a result of this collision, one or...

Some solutes are able to pass directly through the lipid bilayer of a plasma membrane, whereas other solutes require a transport protein or other mechanism to cross between the inside and the outside of a cell. The fact that the plasma membrane is permeable to some solutes but not others is what is referred to as selective permeability.
