Detailed explanation-1: -How does DNA in cells determine an organism’s complex traits? DNA contains codes for proteins, which are necessary for the growth and functioning of an organism. DNA separates into long single strands that make up each part of an organism. DNA produces the energy an organism needs in order to grow.
Detailed explanation-2: -DNA ultimately determines the traits of an organism through gene expression. Gene expression, in turn, is realized via protein synthesis and other cellular functions, dictating structure, metabolism, etc.
Detailed explanation-3: -The sequence of basis on the DNA molecule is what directs the sequence of amino acids in the protein molecule-that’s how it all links together! So, the sequence of bases in DNA codes for the sequence of amino acids of a protein.
Detailed explanation-4: -The genetic code dictates which proteins the cell manufactures. Proteins are strands of amino acids. The sequence of nucleotides in DNA genes determines the order of amino acids in a protein. This is the direct connection between your genes and your traits.
Detailed explanation-5: -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.
