Their are four main valves in your heart. I think it’s common sense that blood gets through your body through veins that come from the arteries of the heart. The blood comes in through the Right atrium, into the right ventricle, up into the pulmonary artery, and into the lungs. When it reaches the lungs it becomes oxygen rich blood. It goes into the second chamber of the heart into the left atrium, down into the left ventricle, up into the aorta, which then pumps blood throughout the whole body. Terms that pump blood- right atrium, right ventricle, pulmonary artery, left atrium, left ventricle, and aorta.

Which is an example of an insertion mutation that changes all of the amino acids that follow the mutation?

astra-53 [7]

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.
