Answer:
The correct option is A. mRNA.
Explanation:
mRNA is a single stranded RNA molecule, complementary to one of the DNA strands of a gene. Also known as messenger RNA, mRNA is synthesized in the nucleus and then exported to the cytoplasm, where the translation machinery (the machinery that actually makes the proteins), binds to the mRNA molecules and reads in them the code to produce a protein specific. During protein synthesis, an organelle called a ribosome moves along the mRNA, reads its sequence of bases, and uses the genetic code to translate each triplet of three bases or codon, into its corresponding amino acid.
The process of fertilization occurs in both plants and animals. There are, of course, differences in the details and mechanisms. On the other hand, some of the similarities are striking. For example, the moss plant has both swimming sperm cells and eggs. In the moss plant, fertilization occurs by the sperm swimming to the egg. Vertebrate animals also carry out reproduction by way of sperm and egg.
One of the differences between plants and animals in this regard is that plants are, for the most part, sedentary. The moss plant depends on rain or very wet conditions in order for the sperm to swim from the male parts of the plant to the egg in the female parts. In the case of animals, the male and female are mobile individuals that physically interact with one another in the process of mating.
