Transcription during Protein Biosynthesis

During protein biosynthesis, transcription occurs in the nucleus of the cell. It is the process by which the genetic information encoded in DNA is transcribed into RNA. This RNA molecule is called messenger RNA (mRNA) and serves as a template for protein synthesis. Transcription takes place in the nucleus because that is where the DNA is located [[1]].

Translation and the Role of mRNA

Translation is the process by which the mRNA molecule is used as a template to assemble a protein molecule. It occurs on ribosomes, which are located in the cytoplasm of the cell. The mRNA molecule carries the genetic code from the DNA in the nucleus to the ribosomes, where the actual synthesis of proteins takes place. During translation, the ribosomes read the sequence of nucleotides in the mRNA and use it to assemble the corresponding amino acids into a protein chain [[2]].

Dark Phase of Photosynthesis

The dark phase of photosynthesis, also known as the Calvin cycle or the light-independent reactions, occurs in the stroma of the chloroplasts. It does not require light and can occur both in the presence and absence of light. The dark phase utilizes the products of the light-dependent reactions, such as ATP and NADPH, to convert carbon dioxide into glucose through a series of enzymatic reactions [[3]].

Light Phase of Photosynthesis

The light phase of photosynthesis, also known as the light-dependent reactions, occurs in the thylakoid membranes of the chloroplasts. It requires light energy to drive the process. During the light phase, light energy is absorbed by chlorophyll and other pigments, which then convert it into chemical energy in the form of ATP and NADPH. These energy-rich molecules are used in the dark phase to synthesize glucose [[4]].

In summary: - Transcription occurs in the nucleus of the cell, where the genetic information in DNA is transcribed into mRNA. - Translation occurs on ribosomes in the cytoplasm, where the mRNA is used as a template to assemble proteins. - The dark phase of photosynthesis occurs in the stroma of chloroplasts and does not require light. - The light phase of photosynthesis occurs in the thylakoid membranes of chloroplasts and requires light energy.
