The jellyfish move between the twilight zone and the sunlight zone. They do so to be able to feed on the small photosynthesizing organisms at the upper surface of the ocean.
Answer:
Yes, two hydrogen bonds could form between thymine and cytosine.
Explanation:
Cytosine is a pyrimidine base found in both DNA and RNA, and Thymine is a pyrimidine base found in only DNA. Electronegative Oxygen and Nitrogen atoms with free lone pairs are potential hydrogen bond acceptors. Hydrogen atoms attached to very electronegative atoms like Oxygen and Nitrogen have strong partial positive charge and are potential hydrogen bond donors.
One hydrogen bond could form between the C4 carbonyl group on thymine which is a hydrogen bond acceptor and the C4 amino group on cytosine which is a hydrogen bond donor. Also, another hydrogen bond could be formed between N3 of thymine which is a hydrogen bond donor and the N3 of cytosine that is a hydrogen bond acceptor.
It is important to note that hydrogen bond cannot be formed between them because the C2 carbonyl groups found on both bases are both hydrogen bond acceptors.
I think you forgot to give the options along with the question. I am answering the question based on my knowledge and research. <span>The lowest level of environmental complexity that includes both living and non living factors is the ecosystem. I hope that this is the answer that has come to your desired help.</span>
The most likely explanation, for this reason, may be that eukaryotic genes often incorporate introns while prokaryotic genes do not possess such a structural arrangement.
<h3>What do you mean by Gene?</h3>
A gene may be defined as a stretch of DNA that contains genetic information that assists in the production of functional protein.
The type of protein may change when there will be a change in the codons. A eukaryotic gene contains introns that are removed during splicing and the codon that codes for specific amino acid may form.
But in prokaryotic genes, no introns are there, and no splicing mechanism will occur, which leads to the formation of different codons, and finally, an alteration in protein may clearly be observed.
Therefore, the most likely explanation, for this reason, may be that eukaryotic genes often incorporate introns while prokaryotic genes do not possess such a structural arrangement.
