Answer:
2) CAG - TTC - ACG mutates to CAG - TTC - ACC - ACG
Explanation:
Insertions are mutations in which extra base pairs are inserted into a new place in the DNA. The number of base pairs inserted can range from one to thousands!
In option no. 1: We see that there is not addition of a single or more than one base, but the new base sequence is different from the original sequence at three places i.e: TTA - CAC - G
In option no. 2: The insertion of three bases ACC has been made exactly after TTC, the whole sequence and arrangement of bases remain same except this insertion.
In option no. 3: The first base of the sequence T is replaced with A, and all other sequence is same. This type of mutation is called substitution in which one base is replaced by other.
In option no. 4: The last base of the sequence C is deleted, and is not present in new sequence. This type of mutation is called deletion in which a base is removed from the sequence.
Conclusion: Therefore, the best option is 2, in which whole codon is inserted in the DNA base sequence.
 
        
                    
             
        
        
        
Think of it like this.  Horses do a LOT of galloping, which is hard on the feet!  Hooves are a physical ADAPTATION, so that the horses won't experience pain on their journeys.  They're hard, so that the horses don't feel the ground nearly as much.  Now, mountain goats travel over rough terrain, with sharp rocks and steep inclines.  Again, it's really easy for them to get hurt strutting around the mountains, so they evolved hard hooves to protect their feet.
        
             
        
        
        
Difference:
The biological process of sexual reproduction requires the input of genetic material from many people. When a flower self-pollinates, for example, the term "individual" might refer to gamete cells developing as a single physical or even genetic organism. I don't want to substitute the word "cell" for "person," either, as that would eliminate instances of acellular biologic entities that reproduce, like viruses. When a piece of a chromosome from one bacterium is injected into another, it recombines and reproduces there, with or without sporulation, which is one instance of what I consider sexual reproduction but which not all viewers would. My notion just requires some genetic material, even in the form of an episome, not gametes. Asexual phases are included in nearly all forms of reproduction, but I regard all of them to be a part of sexual reproduction when they take place throughout a life cycle that also contains an obligatory sexual phase. Brewer's yeast serves as an illustration of the distinction I make because either the diploid or haploid stage, which could be classified as a gametophyte or sporophyte, can be maintained through an infinite number of mitoses. As a result, I consider vegetative propagation to be asexual reproduction.
Now that you have the difference compare the similarties.
 
        
             
        
        
        
The chromosomal DNA contains genetic information and plasmid DNA contains extra information.
