Answer:

Hershey & Chase concluded. after the experiment that the genetic material that is passed from virus to the bacteria is not the protein coat but DNA. It proves the DNA is the genetic material and not the protein.

After labelling the Phage DNA and protein, Hershey and Chase performed a series of experiments like infection, blending and centrifugation. Hershey and Chase gave full evidence of the DNA being a genetic material by their experiments. To perform the experiment, Hershey and Chase have taken T-2 bacteriophage (invaders of E.coli bacteria).

Why is photosynthesis so important to living organisms?
konstantin123 [22]

Answer:

All living organisms need energy to stay alive, but only producers can directly convert energy into food.

Explanation:

The process of photosynthesis is very important because all living organisms need energy to stay alive, but only producers can directly convert energy into food.

Photosynthesis is the process whereby green plants manufacture their food in the presence of carbon dioxide and water.

  • They take light energy from the sun and produce food materials.
  • The light energy is converted to chemical energy which are stored in carbon chains as glucose.
  • The  chemical energy is then used by other living organisms for their own nourishment.

In cellular reproduction, ___ ALWAYS occurs in 5’ to 3’ direction
attashe74 [19]

Answer:

DNA replication

Explanation:

DNA replication is the process whereby the genetic material (DNA) duplicates itself into two identical copies. This process must occur prior to any cellular division (meiosis or mitosis) in order to ascertain that each daughter cell gets an even and correct amount of DNA.

The process of DNA replication begins with the unwinding of the double stranded DNA molecule into two single strands of DNA. One strand called leading strand runs from 3'-5' while the other strand runs from 5'-3'. However, DNA replication proceeds in the 5'-3' direction.
