Answer:
D-DNA molecule
Explanation:
The process of copying the sequence of DNA nucleotide sequences to the mRNA is called Transcriptions. It is the first stage in gene expression for protein synthesis, and<u> it involves the unwinding of the DNA double strands molecules by enzyme</u><u> </u>DNA Helicase into two free strands,(by melting the hydrogen bonds between organic bases), a process initiated by the binding of enzymes RNA Polymerase to the promoter sites on the DNA template; the alignment of the mRNA nucleotides on the single DNA template strands in 3'-5 direction; the formation of hydrogen bonds between the organic bases of the template DNA and that of the messenger RNA single strands,( and phosphodiesterbonds within RNA nucleotide ), to form DNA-RNA complex.
The copying is done in complimentary anti parallel fashion;5'-3' prime. direction.
The hydrogen bonds, between the bases DNA-RNA complexes breaks,and the releases the mRNA which exists through the nuclear pores.Thus this <u>leads to copying of the the coded messages as seqeunce of DNA , from the DNA to the mRNA for gene expressions.</u>

Answer: 6CO2 + 6H2O -> C6H1206 + 6O2
Explanation: This is a balanced chemical equation for photosynthesis. In photosynthesis, six molecules of carbon dioxide react with six molecules of water in the presence of sunlight to form one molecule of glucose and six molecules of oxygen. Photosynthesis is a process by which green plants manufacture their own food using sunlight. Plants cells have an organelle known as chloroplast which contains chlorophyll a green pigment that traps energy from the sun. The energy trapped by the chlorophyll is used by plants in the presence of carbon dioxide and water to drive the synthesis of glucose with the release of oxygen as the by-products.
