DNA is copied during mitosis and when the two resulting copies of DNA are compared they are found to contain the same order of nucleotides is not the result of mutation in the DNA sequence of an organism.
Explanation:
Mutation is the process
It is caused by certain chemicals called mutagens or by environmental factors.
In mutation the nucleotide get change which eventually changes the protein product.
In mutation purine base gets mutated to purine base and pyrimidine base gets mutated to pyrimidine only.
A single change in nucleotide is called point mutation and the effect occurring because of it is called frame shift mutations.
In S phase there are checkpoints which ensure that DNA replication is accurate and when mitosis follows it equal distribution of DNA takes place between the two daughter cells hence no mutation will takes place.
Answer:
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
Explanation:
Endocytosis enables extensive particles to enter the cell, and exocytosis ousts vast atoms from the cell. Along these lines, the cell can acquire things it needs and disposes of things it doesn't. Exocytosis is the turn around process, where a cell ousts substantial particles, generally squander from cell forms.
Answer:
They contain different genetic material.
Explanation:
DNA viruses contain DNA for genetic material while RNA viruses contain RNA. When RNA viruses enter a host cell, they must convert their RNA into DNA. DNA viruses change the biochemical functions in the nucleus for DNA replication and creates RNA that controls the proteins needed by the DNA virus (capsid).
