Sickle Cell Anemia: A Mutation Story

... When the two alleles for some gene are the same, we say the individual is “homozygous” for that gene. When the two alleles are different we say the individual is “heterozygous” for that gene. Sometimes one allele will clearly be dominant over the other. For example, the allele for proteins that lead ...

Assembling the Sequence of the Genome

Now, entire genomes are being sequenced at incredible speeds. Yet, obtaining a complete genome sequence is not the end of the road. Understan ...
