Question

What is the "central dogma"?

A. The earliest cells on Earth most likely used RNA to store and copy genetic information.
B. The ability of a cell to survive depends on the accurate duplication of genetic information carried in its DNA.
C. Within the cell, genetic information flows from DNA to RNA to protein.
D. Much like all viruses, all cells use DNA to encode genetic information.
E. For a given individual, the genetic information contained in the DNA of every cell is identical.

Answer 1

The "central dogma" describes the sequence of information transfer from DNA to RNA to protein in cells, involving the processes of transcription and translation.

Step-by-step explanation:

The "central dogma" of molecular biology refers to the flow of genetic information within a cell, which moves from DNA to RNA to protein. Specifically, the term describes how genetic instructions are carried in the DNA of a cell, transcribed into messenger RNA (mRNA), and then translated into proteins. The process begins with transcription, where a section of DNA is used as a template to create an mRNA molecule. Following this, translation takes place, in which the sequence of nucleotides in the mRNA is decoded into a sequence of amino acids to build a protein. This fundamental concept is vital to understanding how genes direct the production of proteins, which are essential for cell function and structure.
