ACTUAL QUESTIONS AND ANSWERS WITH COMPLETE
SOLUTIONS VERIFIED
Define the term "human genome"
A complete set of genes that builds an entire organism.
What is the difference between gamete and non-gamete cells?
Gametes fuse with another cell during reproduction (haploid) non-gamete cells are
diploid.
What is a karyotype?
An organized profile, or picture, of a person's chromosomes
What is a Barr body?
The inactivated x chromosome in a cell
What is the definition and function of a gene?
A sequence of nucleotides that forms part of a chromosome. They act as instructions to
make proteins.
What determines which genes are active ("switched on")?
Transcription factors affect the transcription of proteins and activate certain genes and
repress others
Define genotype
one's genetic constitution
Define phenotype
