Worked Solution & Example Answer:What is the definition of the genome? A - OCR Gateway - GCSE Biology - Question 4 - 2023 - Paper 4
Step 1
C. All the genetic material that is present in an individual.
Answer
The genome refers to the complete set of genetic material present in an organism. This includes all coding sequences (genes) as well as non-coding regions within the DNA. Therefore, the correct definition encompasses both alleles expressed in the phenotype and those not expressed, making option C the most comprehensive and accurate. It is critical to understand that a genome consists of all the DNA—both functional (coding) and non-functional (non-coding)—that determine the biological capabilities of an individual.
