<span>DNA contains the code for all an organism's protein. Since many of the organism's structures, processes, and growth depend on protein the DNA is central to the well being of all organisms. In eukaryotes, the DNA is locked up in the nucleus. The area of the cell where proteins are made is in the cytosol (ribosomes). In order for the protein to be made the DNA has to produce a copy of the blueprint m-RNA. This messenger RNA will take the code to the ribosome. The process by which m-RNA is made is called transcription. A-U, C-G base pairing rules. Once on the ribosome another RNA comes into play t-RNA. This is called transfer RNA. Here it will take an amino acid and place it in the correct order to produce the desired protein. This is called translation. It begins with a start co don AUG. and ends with a stop codon. The protein will then go to the Golgi apparatus and be formed into its final shape.

B) Photosynthesis The Sun is the ultimate source of all energy in the universe. Plants being the main primary producers or autotrophs, use solar energy to make their own food through photosynthesis, thus converting energy into the organic matter that can be consumed by all organisms. They form the basis of almost all food chains from where consumers derive their food.
Answer:
Option B. Renewable have no environmental concerns associated with them; nonrenewable cause damage to the environment.
Explanation: Renewable resources are those substances which can be recycled or reused after using it. Examples of renewable resources are hydro energy, solar energy and tidal energy etc. Renewable resources are occurs naturally while nonrenewable resources are those substances which cannot be recycled. These substances causes pollution in the environment. It is also found naturally. Examples are petrol, diesel and wood etc.

Answer
Photosynthesis yield sugar in two main steps
1. Light reaction
In this step plant absorb sunlight which cause photolysis of water and excitation of electron. this electron flow through Z-scheme and atlast enter into NADH, the end product of light reaction is ATP and NADH₂.
2. DArk reaction.
In this step ATP and NADH₂ are used as raw materials. it occurs in stroma of chloroplast. here CO₂ is used through Calvin cycle and at the end glucose is prepared.
