The answer to your question is,
DNA provides instructions to cells in forming an organ.

I suppose the yellow peg is facing the green peg, in which case the green peg must be guanine.
The bases are associated in pairs. In each pair there is always a purine associated with a pyrimidine. The association is by weak bonds: the hydrogen bonds, two bonds for an AT pair; three links for a GC pair. When we know the sequence of one strand we can deduce the sequence of the other strand. The two strands are oriented opposite to the 3 'and 5' ends (the strands are called antiparallel).
1. Initiation: ribosome assembles itself around mRNA and first tRNA attaches at start codon
2. Elongation: tRNA transfers amino acid to next tRNA, amino acids attach, and ribosome shifts by one codon so first tRNA detaches. This continues and forms an amino acid chain.
3. Termination: when tRNA encounters a stop codon, the process ends and polypeptide chain is folded into final form.
Answer and Explanation:
Image result for How did the results prove the semiconservative model of DNA
The experiment done by Meselson and Stahl demonstrated that DNA replicated semi-conservatively, meaning that each strand in a DNA molecule serves as a template for synthesis of a new, complementary strand. Although Meselson and Stahl did their experiments in the bacterium E.
