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).
Hello,
Question- In a particular species brown fur is dominated over white fur. So how could an individual in the specias have tan fur?
Answer- well there are many possibilities of why that specias has TAN fur it can start from there parents had brown fur till they was standing in the sun for to long or even that there habbitat is different temp.
Important- If my answer helped you please mark me as brainliest thank you and have the best day ever!
Answer:
The cell membrane holds the cell's internal contents from its environment.
The cell membrane is comprised of two layers of fat.
The cytoplasm is a liquid in which the various organelles of the cell are suspended.
The cytoplasm keeps organelles in place. It also allows different materials to flow from one organelle to another.
The nucleus of a cell contains genetic material. DNA, RNA and mitochondria replicate in the nucleus. The nucleus also produces and replicates proteins, and sends the proteins to other parts of the cell.
I hope this helped
B) 100% of the parent because when DNA copies itself, everything is replicated exactly.
