What would happen if hydrogen bonds form between any two nitrogenous bases in dna

I believe that identical copies of original DNA wouldn't be formed.
DNA has a strict pairing rule, adenine can only go with thymine, and cytosine can only go with guanine.
This is because of thymine and adenine make 2 hydrogen bonds between each other, while cytosine and guanine form 3. Therefore bonding out of this order is impossible (unless it's a mutation in which there are exceptions).
When DNA replicates, each strand of the original DNA serves as a template for the new strand of DNA. Hence the new strand that goes with the first original DNA strand is the same as the second DNA strand.
If the bonding between the nitrogen bases is messed up, the new strand of DNA will not be exactly what it should be. To demonstrate, if the nucleotide is thymine for the original strand, the new strand should be adenine. However, if the bonding is arbitrary, then the new strand could be cytosine or guanine as well, therefore there is no definite answer to what the new strand should be. This will make havoc in the genetic codes and will most likely kill the organism.
I hope this answer has answered your question and good luck with your assignment. I apologise if I am incorrect. Have a good day/night.

Answer:

b. skin from mouse 2

Explanation:

According to this question, a mice skin transplant is being conducted. Four mice labelled Mouse 1, Mouse 2, Mouse 3 and Mouse 4 are used for this experiment. A small patch of skin from mouse 2 (the donor) was transplanted onto mouse 1 (the recipient), however, it was eventually rejected by the recipient (mouse 1).

This transplant rejection is due to the fact that the recipient's immune system identifies the tansplanted skin as foreign, hence, begins to attack it, leading to the skin's necrosis or death. Based on this, the same transplant rejection will occur if skin patches from mouse 3 and 4 are used.

However, the immune system of mouse 1, which is the recipient, will identify skin patches from MOUSE 2 as less foreign than any other skin from other mice. This is because skin from that mouse has been used before, hence, the recipient's immune recognizes it when a follow-up transplant is conducted. This makes a follow-up transplant from MOUSE 2 be the least likely to be rejected.

The correct answer to this question is this one: "Since they eat lower on the trophic level and don't expend much energy they are able to grow larger."

The giant baleen whales can grow so large because they eat lower on the trophic level and don't expend much energy they are able to grow larger.
