DNA fingerprinting is where DNA is used to create a profile for someone often in crimes. The STR or Short Tandem Repeats are used for this. STRs are non-coding sections of DNA which repeat themselves for example CACACACACACACACACACA the location of this STR and the length of the STR (how many times it repeats) are used to identify a specific person
So that they don't explode.
AKA with a thing called osmosis (transportation of water through cells.)
B- Enzymes act as catalysts to speed up chemical reactions
Answer:
Harshey and chase labeled T2 bacteriophage with radioactive sulfur and radioactive phosphorus. As DNA contains phosphorus, not protein and protein contain sulfur, not phosphorus, therefore, the presence of radioactivity in cell can determine which is the genetic material
.
Then Harshey and Chase infected <em>E.coli</em> with T2 bacteriophage and centrifuged the cell. They found radioactive phosphorus in cell pellet and radioactive sulfur in supernatant.
So by this experiment, they concluded and proved that DNA is the genetic material that gets transfer from one generation to another.
Answer:
1. RNA polymerase binds to the promoter.
2. DNA strands are unwound and separated
3. The complementary RNA nucleotides are added.
Take a look at the attached picture. First, the RNA polymerase must bind to the promoter region to initiate the whole process. DNA must be unwound by DNA helicase, then it will make the RNA transcript, which consists of adding the complementary RNA nucleotides to the DNA strand. Then the transcript leaves the nucleus and begins translation.
