Answer:
The correct option is D. Chemoautotroph uses CO2 for carbon and H2 for energy.
Explanation:
Autotrophs can be described as organisms that are capable of making their own food. There are two types of autotrophs: photoautotrophs which use energy from the sunlight to produce food and chemoautotrophs have the ability to make biological compounds from inorganic matter.
The chemoautotrophs are capable of taking carbon from inorganic sources and converting them into useful organic compounds. They are also capable of taking hydrogen atoms and use them for deriving energy. Hence, D is the correct answer.
The second step is:
Genetic information for synthesis of the specific protein is transcribed on to mRNA.
This process is called transcription and takes place in the nucleus. With the help of an enzyme called RNA polymerase, a particular segment of DNA is copied onto a strand of RNA which is called messenger mRNA because it will carry this coded information from the nucleus and into the cytoplasm to the ribosomes for translation. mRNA is therefore a kind of "messenger."
In the ribosomes the information is translated or "decoded" and with the help of another type of RNA called transfer RNA (tRNA), amino acids are assembled according to the decoded information to make the specified protein.
