A. balanced. equal forces acting on one object in opp dirrections are called balanced forces. i know i am correct lol i hope this helps you :)
Out of the following, the one that would most likely happen if DNA polymerase were not functioning properly during DNA replication is the new strands of DNA would not be an exact copy of the original DNA. So the correct answer will be C.
Answer:
One band of light density and one band of heavy density.
Explanation:
According to conservative model of replication, the original strands do not separate from each other during replication. Hence, after replication the old strands are together and the new strands are together.
Here, cells were grown in 14N medium first so 14N was used for DNA replication and all DNA molecules had 14N. When the cells were transferred to 15N medium, only 15N was available for replication process. New DNA molecules would be synthesised using 15N (15N15N) and old DNA molecules have 14N (14N14N). Hence, in density gradient one band will be of light density (14N14N) and one band will be of heavy density (15N15N).
Scientists use fossils to learn about organisms' lives and evolutionary relationships, to understand geological change, and even to locate fossil fuel reserves.
