|
DNA codes for mRNA which determines the properties and traits of an organism.
|
|
|
DNA codes for the amino acid sequences of the body’s proteins. Proteins determine the traits of an organism.
|
|
|
DNA codes for tRNA which then determines the traits of all organisms.
|
|
|
mRNA codes for DNA which then determines the amino acid sequence of the body’s proteins.

Detailed explanation-1: -DNA initially transcribed to messenger RNA, consists of coding sequences which are called as exons which codes for proteins and non-coding sequences which are called as introns.
Detailed explanation-2: -genetic code, the sequence of nucleotides in deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) that determines the amino acid sequence of proteins. Though the linear sequence of nucleotides in DNA contains the information for protein sequences, proteins are not made directly from DNA.
Detailed explanation-3: -Like words in a sentence, the DNA sequence of a gene determines the amino acid sequence for the protein it encodes. In the protein-coding region of a gene, the DNA sequence is interpreted in groups of three nucleotide bases, called codons. Each codon specifies a single amino acid in a protein.
