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.
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.
Many scientists think that DNA was the first genetic material?
yes
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 kind of trait appeared in the first generation?
In the first generation, new traits arise from the combination of genetic material from the two parent organisms. These traits result from the recombination of genetic material during reproduction, leading to genetic diversity in the offspring.
The first genetic material was most likely?
RNA, as it is capable of storing genetic information and catalyzing chemical reactions like proteins, making it a plausible candidate for the earliest genetic material. RNA can also self-replicate, providing a mechanism for passing on genetic information to future generations.
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 the process whereby genetic material is exchanged between homologous chromosomes during synopsis of the first meiotic division?
The process is called genetic recombination or crossing over. It involves the exchange of genetic material between homologous chromosomes, resulting in the formation of new combinations of alleles. This increases genetic diversity among the offspring.
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!
Can one mans sperm affect the outcome of a embryo from a different man?
No, once the embryo is formed, the genetic material from the sperm of the first man cannot affect it. The new embryo will carry genetic material only from the father whose sperm fertilized the egg.
