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.
Explanation:
yes the 4th one is right so yes the one you have is right
Answer: Option D) Arthropods
Explanation:
Arthropods are the largest phylum in the animal kingdom. It is divided into the following classes:
- insects e.g grasshopper
- crustaceans e.g crab
- myriapods e.g millipedes
- Arachnids e.g spider, lobster etc
Hello. You did not enter the text to which these questions refer, which makes it impossible for them to be answered. However, I will try to help you in the best possible way.
It is only possible to answer your questions in a specific way by reading the experiment, however, I can inform you that formites are objects that allow the colonization and growth of microorganisms that can be major causes of diseases. Among these microorganisms are bacteria, fungi and viruses of the most varied species. Among these microorganisms, both fungi and non-demanding bacteria can grow in a nutrient agar culture medium. This is because this is a very simple culture medium where bacteria that do not need specific nutrients can grow and where most fungi can grow too. However, it is impossible for viruses to grow in this type of culture medium or in any culture medium, since viruses only develop inside a host's organism. Bacteria known as fastidious would also not grow in this type of culture medium, since they only grow with the presence of very specific nutrients.
