AP BIOLOGY

Detailed explanation-1: -That’s known as the central dogma of molecular biology. It states that “DNA makes RNA makes protein.” Really it means that the genetic information within DNA is used to make smaller molecules of RNA, which leave the nucleus and then the genetic information in RNA is used to assemble amino acids into proteins.

Detailed explanation-2: -In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.

Detailed explanation-3: -Thus, during expression of a protein-coding gene, information flows from DNA
