During which process is messenger RNA formed?

Answer 1

The cellular process shown by the diagram is transcription and translation, where transcription within the nucleus generates mRNA, which is then translated into protein in the cytoplasm. cDNA sequencing is a method that focuses on genes actively expressed as proteins.

Step-by-step explanation:

The cellular process depicted by the diagram is transcription and translation, which are critical stages in the central dogma of molecular biology. Messenger RNA (mRNA) is formed during the process of transcription, where the information coded in DNA is used to create an mRNA molecule. This process occurs within the cell nucleus. The mRNA then travels out of the nucleus and into the cytoplasm, where translation occurs. During translation, ribosomes and transfer RNA (tRNA) molecules work together to decode the mRNA into a protein.

Here is the correct order for the processes involved in protein production:

1. Transcription
2. Traveling of mRNA out of the nucleus
3. tRNA binding to mRNA
4. Folding of the polypeptide

DNA sequencing of cDNA, or complementary DNA, is particularly useful for understanding an organism's proteins as cDNA represents only the genes that are actively being expressed into mRNA and subsequently proteins, rather than the entirety of the genome, which includes non-coding regions.
