Who was the first person to declare DNA to be the genetic material?

In 1928, Frederick Griffith was able to transform harmless bacteria into virulent pathogens with an extract that Oswald Avery proved, in 1944, to be DNA. In 1952, Martha Chase and Alfred Hershey used radioactively labeled virus DNA to infect bacteria, proving the same point.

Are viruses prokaryotes?
First off a prokaryotic organism is a thing that has no nucleus that holds it's genetic material. Viruses are prokaryotes. Their genetic material isn't in a nucleus. It has an inner core that holds its genetic material, and the inner core is protected by the virus's protein coat.
What is the process whereby genetic material is exchanged between homologous chromosomes during synopsis of the first meiotic division?
Crossing over or homologous recombination
What type of cell divides by the cell membrane pinching together until the two cells split apart?
This is a stage in most cell divisions. The genetic material has to replicate first.
Is nucleus divides twice during meiosis?
yeap yeap, it divides twice. (: the first one is the 'separation of the homologuous chromosomes' (note that the crossing over of genetic material have already taken place). the second division is the separation of the chromatids AT the centromere. (: this will then give rise to genetic variation. :D
What is the genetic material in eukaryotes?
The nucleus holds the cells genetic material in eukaryotes. The genome of eukaryotes is sequestered to a membrane bound organelle called the nucleus. The nucleus is the site of replication and transcription.
The first person to declare DNA to be the genetic material was?
Oswald Theodore AveryHe was one of the founding fathers of immunochemistry (the study of the chemical aspects of immunology) and a major contributor to the scientific evolution of microbiology.
The first genetic material was most likely?
RNA
Many scientists think that DNA was the first genetic material?
yes
What did Aristotle declare that people are motivated to do?
Aristotle was the first to declare that the ultimate goal of every person is the desire to be happy.
Which comes first the artist's imaginary or the material?
The material comes first because it is not a person who made it. The artist is only a person that uses the material for art.

What does the offspring of asexual reproduction receives?
The same genetic material from the single parent. In a word they are clones of the first.
When the genetic material was first being isolated and studied there was a controversy about it being DNA or protein-- those that backed protein as the genetic material almost got it right-- explain?
Scientists thought genetic material was a protein not DNA because there are 20 different amino acids for a building of a protein polymer, while DNA polymers only have 4 nucleotide bases.
What is interkinsis?
Interkinesis is the period between the first and second divisions in meiosis. Meiosis is a special type of cell division of genetic material (DNA). Meiosis produces genetic diversity.
What Is an organism cell or piece of genetic material that is genetically identical to one from which it is derived?
That cell is a clone of the first. This happens all the time in your body.
The first thing Roosevelt did to declare a?
The first thing Roosevelt did to declare what?? Can't answer your ? if you don't finish it!
How does a virus sustain life in its host?
First things first a virus is not living. The virus injects its Genetic material (G.M. for short) and and makes the bacteria make more viruses.
