Worked Solution & Example Answer:For humans, the term nuclear genome refers to all the genes in A - VCE - SSCE Biology - Question 9 - 2006 - Paper 1
Step 1
D. a set of autosomes plus the sex chromosomes.
Answer
The nuclear genome in humans encompasses all genetic material found within the nucleus of a cell. This includes the genetic information contained in the autosomes as well as the sex chromosomes (X and Y).
To explain further:
- Autosomes: These are the chromosomes that are not involved in determining the sex of an individual. Humans have 22 pairs of autosomes.
- Sex chromosomes: These determine an individual's sex. In humans, there are one pair of sex chromosomes (XX for females and XY for males).
Thus, the correct interpretation of the term nuclear genome is option D, as it includes both autosomes and sex chromosomes.
