The Hershey–Chase experiment was based on a bacteriophage T2 (a virus), to that DNA is the genetic material. Bacteriophage T2 attacks bacterium and makes its copies. Based on the experiment, Hershey and Chase deduced that it is the DNA of virus enters bacteria to make virus copies. To trace viral DNA, Hershey and Chase label DNA with ³²P (radioisotope of phosphorus) because phosphorus is not present in most of the proteins.
Answer:
I think it false. Hopes this helps! :3
Answer:
silent mutation is the correct answer.
Explanation:
- Silent mutation does not change in the amino acids because of this function of protein remain unchanged and protein is functional.
- A silent mutation is a kind of point mutation that changes the single nucleotide sequences.
- It is called a silent mutation is called silent because this kind of mutation does cause any change in the protein which is formed.
- sickle cell anemia, phenylketonuria, fibrosis, Tay-Sachs disease are the diseases caused by silent mutations.
This is because twenty-four latitude lines were chosen so that 24 hours represents a 360 revolution around the planet. As earth spins on its axis, different places receive sunlight at different times. Each day goes from morning to night as earth turns because the earth spins from west to east therefore the day moves from east to west. Lines of longitude help us keep track of time differences from place to place. Mapmakers divided earths 360 degrees of longitude by 24 hours which results to 15, the time changes by one hour every 15 degrees. It is one hour earlier every 15 degrees of longitude to the west and it is one hour later every 15 degrees of longitude to the east.
