This is a process called transcription and translation.
Information to synthesize a particular protein is found in DNA in the cell nucleus. This information is copied (transcribed) onto messenger RNA or mRNA in short. The copying process is called transcription.
mRNA then leaves the nucleus and enters the cytoplasm where it attaches to a ribosome. Transfer RNA or tRNA then begins to read (translate) the information on the attached mRNA. This is the process of translation.
tRNA then fetches amino acids that correspond to this information and brings them to the ribosome where they are linked together into a chain. This chain of amino acids is the primary structure of the protein.
The size of the proboscis helps the moth to consume the food (nectar) easily from Darwin's orchid.
<h3>What do you mean by Adaptation?</h3>
Adaptation may be defined as the process of modifying one's characteristics to better suit a situation and survive more efficiently.
The size of the tube that produces nectar is just 27.9cm long, while the length of the proboscis of a moth is 30.5cm. It easily consumes the nectar and gets energy for survival as well as reproduction.
Therefore, the size of the proboscis helps the moth to consume the food (nectar) easily from Darwin's orchid.

Answer:
Threonine
Explanation:
Using the amino acid chart, the mRNA strand ACU corresponds to the amino acid Threonine.
The correct option is this: TWO DRAGONFLY SPECIES REGULARLY MATE BUT THEIR GAMETES ARE INCOMPATIBLE.
In biology, there are different types of reproductive barriers, one of these is prezygotic barrier. A prezygotic barrier is a kind of mechanism that prevent reproduction from occurring by blocking fertilization. In this case, the concerned species will be mating together, but their gametes will not be compatible and thus, zygote will not be formed.
A postzygotic barrier on the other hand is said to occur when the reproduction process is blocked after the formation of zygote or after fertilization has taken place. A good example of this is an hybrid mule that is sterile and can not reproduce.
