Final answer:
The statement is true; genes do have specific starting and ending points on the DNA sequence from which the genetic code is read in one direction to synthesize proteins.
Step-by-step explanation:
The statement each gene has a starting point and an ending point, with the DNA code being read in one direction, is true. Genes are segments of DNA that contain the instructions for building proteins. Transcription begins at a specific site on the DNA called a promoter, which is the starting point. It proceeds until a termination sequence is encountered, which marks the ending point. The process of protein synthesis includes the steps of transcription and translation. During transcription, an mRNA copy of the gene is synthesized. This mRNA is then translated into a protein, following the genetic code where codons represent amino acids or function as start or stop signals. The start codon AUG sets the frame for reading the genetic code, and translation continues until a stop codon is reached.
