Answer:
The following scientists have performed different experiments that were helpful in providing evidence that DNA is the genetic material. The summarize experiments are as follows-
1. Fredrick Griffith- the experiment was an experiment performed in 1928. It was one of the experiments that exhibit that bacteria can acquire through the process of transformation.
2 Oswald Avery, Maclyn McCarty, and Colin MacLeod: this experiment exhibited that DNA can transform the cell properties, and clarifying the chemical properties of the genes.
3. Alfred Hershey and Martha Chase: They determined that even the bacteriophage has a protective coat around it but the DNA that is present inside is the genetic material that has the ability to produce the progeny inside a bacterium.
4. Erwin Chargaff: He proposed tow rules which were named after him as chargaff rules. This tells that natural DNA the number of cytosines is equal to the number of guanine units and adenine to Thymine units.
Answer:
a cell takes in DNA from outside the cell then the external DNA becomes a component of the cell's DNA.
Explanation:
Transduction. This processes involves insertion of bacteriophage (viruses that infect bacteria) into the genome of a bacteria resulting to recombination. The bacteriophage DNA could contain virulent factors that convert an avirulent bacteria into a virulent type
Answer:
I calculate the buoyancy force as: Volume of the sphere = Volume of the water displaced (Vdisplaced) = (4/3)πr3. Weight of the displaced water = Buoyancy force (B) = Vdisplaced× density of water.
I hope this is what you needed
Answer:
Herbívoros
Explanation:
Son animales que se alimentan exclusivamente de plantas, pastos, hierbas y vegetales en general. Hay muchos herbívoros que comen huevos y a veces otras proteínas provenientes de animales. Ejemplos de herbívoros: caballo.
