How is the information in a DNA molecule expressed in an organism?
A
through plasmids
B
through RNA polymerase
C
through recombinant DNA
D
through proteins
Explanation: 

Detailed explanation-1: -It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene’s DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.

Detailed explanation-2: -To manufacture protein molecules, a cell must first transfer information from DNA to mRNA through the process of transcription. Then, a process called translation uses this mRNA as a template for protein assembly.

Detailed explanation-3: -DNA encodes information through the order, or sequence, of the nucleotides along each strand. Each base-A, C, T, or G-can be considered as a letter in a four-letter alphabet that spells out biological messages in the chemical structure of the DNA.

Detailed explanation-4: -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.
