Locus
Chromosome
During DNA replication, the strands separate by
DNa polymerase
topoisomerase
unwindase/helicase
gyrase
Haemophilia is more common in males because it is a
recessive character carried by Y-chromosome

dominant trait carried by X-chromosome
recessive trait carried by X-chromosome
The process of translation is
ribosome synthesis
protein synthesis
DNA synthesis
RNA synthesis
An allele is dominant if it is expressed in
both homozygous and heterozygous states
second generation
heterozygous combination
homozygous combination
If the two alleles are different, then the organism is:
