Question

CONNECTIONS ACADEMY HELP biology LESSON 20 UNIT 4 TEST PLEASE i'll help you with another class 6. The Hershey-Chase experiment proved that DNA was the hereditary material because (1 point)
radioactive phosphorus in viral proteins was shown not to enter bacterial cells.
radioactive phosphorus in viral DNA was shown to enter bacterial cells.
radioactive sulfur in viral proteins was shown to enter bacterial cells.
radioactive sulfur in viral DNA was shown not to enter bacterial cells.

Answer 1

7. Which of the following is a nucleotide found in DNA? (1 point)
adenine + phosphate group + thymine
cytosine + phosphate group + guanine
deoxyribose + phosphate group + polymerase
deoxyribose + phosphate group + cytosine
8. How does replication of the lagging strand of DNA compare with replication of the leading strand? (1 point)
The replication process is identical for both strands.
Okazaki fragments are made on the lagging strand but not on the leading strand.
The leading strand is copied in one direction while the lagging strand is copied in the opposite direction.
DNA ligase works on the leading strand while DNA polymerase works on the lagging strand.

Answer 2

can someone just post the answers, i'm really behind

Answer 3

We are acturly not allowed just to give the answer, after the warrning given lately anyone who do so get suspended. However I help you the best I can.

Answer 4

6) you can eliminate 2 by thinking of what DNA consist of, the final answer you can find by thinking about what would have to enter the cell in order to make the virus proteins.

7) DNA or in this case better spokken about as DeoxyriboNucleic Acid consist as the name say of a sugar (ending on ose), a nitrogenous base and a phoshate group.

Answer 5

Hey. Do you have the unit test: Chemical Reactions, Acids and Bases. I'm also from CA I'm having so much trouble with this. Please help me. It would mean the world to me.
