How does carbon dioxide concentration affect photosynthesis rate?
DiKsa [7]
Increasing the concentration of carbon dioxide increases the rate of photosynthesis, as there is a greater supply of it that can be used. Of course, you can only add so much carbon dioxide before the plant can’t perform photosynthesis at an any faster rate. Increased carbon dioxide concentration will increase the rate of photosynthesis until it is no longer the limiting factor in the reaction.

Mrac [35]

The correct answer is option A, that is, DNA is photocopied to make RNA.

Transcription refers to the procedure by which DNA is transcribed or copied to make mRNA (messenger RNA) that conducts the information required for the formation of protein.

The pre-messenger RNA is then amended to generate the desired molecule of mRNA in a procedure known as RNA splicing.
