Your question should have a picture in other to answer the question:)
Answer:
HeLa cells, like many tumours, have error-filled genomes, with one or more copies of many chromosomes: a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.
Explanation:
The genotype of the Q gene is homozygous dominant because it has 2 dominant genes and when a genotypes has two of the same type of genes it is homozygous. If it has different genes it is heterozygous.
hopefully this helps
They consist of double-bond and single bond, according to the type of DNA.
Complex molecules are made up of other elements bonded with carbon. Carbon is able to bond with other molecules so easily because it has four valence electrons.
