Explanation
3. In the Regeneration Phase (Phase III) of the Calvin cycle, Ribulose 1,5-bisphosphate (RuBP) - the molecule that actually starts the cycle, is regenerated from Glyceraldehyde 3-phosphate (G3P) so that the cycle can continue. ATP is also used in this process.
4. During the process of translation, ribosomal subunits assemble together on the mRNA strand to perform translation. The ribosome decodes the mRNA sequence and a long, continuous chain of amino acids emerges to form a polypeptide or a protein.
5. In the light-dependent reactions of photosynthesis, splitting water molecules into oxygen gas, hydrogen ions and electrons produces the required energy for subsequent electron and proton transport.
6. The translation is the process in which ribosomes synthesize proteins from mRNA. It is the process of translating the sequence of a messenger RNA (mRNA) molecule into a sequence of amino acids.
7. Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).
8. In most eukaryotic genes, coding regions (exons) are interrupted by non-coding regions (introns). During the process of RNA splicing, introns are removed and exons joined to form a contiguous coding sequence and sent to a ribosome for translation.
9. In transcription, a region of DNA opens up to be read by the ribosome. One strand - the template strand - serves as a template for the synthesis of a complementary RNA transcript.
