Answer:
b. mRNA from DNA
Explanation:
Transcription is the process of synthesis of RNA using a DNA template strand. The process of transcription occurs inside the nucleus in eukaryotes as their DNA is present in the nucleus.
The process includes unwinding of DNA double helix to expose the DNA template strand. The enzyme RNA polymerase binds to the specific start sites on the DNA template strand and starts making its RNA copy.
The newly formed RNA undergoes modification in eukaryotes before serving as a template for protein synthesis. However, in prokaryotes, the process of transcription and translation can occur simultaneously.
Answer:
The electron transport chain is the third and final step of cellular respiration. At the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen which the cell has consumed and reacts with it to form water. Therefore, water is created as a byproduct of the metabolism reaction.
