Biology

Stolb23 [73]3 years ago
4 0
Hershey and Chase studied bacteriophages which are viruses that attack bacteria. They labeled the bacteriophage with radioactive isotopes to see where it goes when a virus attacks. They discovered that nearly all the radioactivity was found in phosphorus, confirming that DNA contains genetic material, not protein.

In which situation could a mutation be passed on to the offspring in an organism?
Goryan [66]

Answer:

A mutation could be passed on to an offspring by inheritance.

Explanation:

These 4 scenarios that can occur are autosomal dominant, autosomal recessive, x-linked dominant and x-linked recessive. Autosomal dominant is when both parents have the disorder and pass it on to one of their children but not the other. This means that both parents are heterozygous. Heterozygous is a when a gene has one dominant allele and one recessive allele. Autosomal recessive is when both parents don’t have the disorder but one of their offspring do. This also means that both parents are heterozygous. Next is X-Linked dominant. This can occur when one of your grandparents has the disorder and passes it on to your dad and as a result all of his daughters are affected. Lastly, X-Linked Recessive is similar but it’s the mother that gets the disorder and passes it on to her sons. This process can really help determine whether or not your child has a disorder and is completely healthy.
