Hey, I believe your answer would be D. Sugar ribose and the base uracil. I believe this is the answer, because RNA consists of sugar ribose, adenine, guanine, cytosine, and uracil.
Your first option is incorrect, because that's DNA. Where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.
Your second option is also incorrect, this is because sugar deoxyribose is in DNA, and uracil is in RNA. These two do not make sense together.
Your third option being incorrect, because sugar ribose is in RNA, but not the base of thymine. RNA consists of uracil, not thymine.
Lastly your fourth option being correct! This answer is correct, because both sugar ribose, and the base uracil are in RNA!~
Answer is D. Sugar ribose and the base uracil.
Both of these enable direct material transfer across cells.
<h3>What purpose do plasmodesmata and gap junctions serve?</h3>
Gap junctions are pathways between adjacent cells that allow for the passage of ions, nutrients, and other materials that facilitate cell communication, much like plasmodesmata in plant cells.
<h3>What features of gap junctions and plasmodesmata are similar?</h3>
In that they are channels between adjacent cells that permit the transfer of ions, nutrients, and other materials that enable cell communication, gap junctions in animal cells are similar to plasmodesmata in plant cells.
<h3>Are plasmodesmata and gap junctions similar in structure?</h3>
Plasmodesmata and gap junctions are similar in structure.
<h3>
Which four types of cell junctions are there?</h3>
Desmosomes, tight junctions, gap junctions, and plasmodesmata are a few examples of several intercellular connections.
