Sickle-cell anemia is an example of codominance. What implications does this have for people with one or two copies of the sickl

e-cell gene?
A. People with two copies of the mutated gene have healthy red blood cells. People with one copy of the mutated gene don't have the disease but are carriers of the disease.
B. People with two copies of the mutated gene have sickle-cell anemia. People with one copy of the mutated gene have both healthy and misshapen red blood cells and are carriers of the disease.
C. People with two copies of the mutated gene are carriers of the disease. People with one copy of the mutated gene don't have the disease.

Answer: B - People with two copies of the mutated gene have sickle-cell anemia. People with one copy of the mutated gene have both healthy and misshapen red blood cells and are carriers of the disease.

Explanation:

Co-dominance is when both the alleles of a gene in a heterozygote show. In the case of sickle cell anemia (since it is a co-dominant trait) even if the person only has one sickle cell allele, symptoms of sickle cell will still show up in that person. That's why the person in this example has both misshapen and healthy red blood cells.

The lagging strand runs in a _________ direction and is replicated _________.
e-lub [12.9K]

The lagging strand runs in a   5’ to 3’ direction and is replicated  discontinuously.

<h3>Why a discontinuous or delayed tape?</h3>

The other strand, called delayed, is replicated discontinuously. In this case, the presence of Okazaki fragments is necessary, small pieces of DNA that will bind to form a new strand. - DNA is degraded by two types of enzymes.

The ends of a DNA strand are classified as 5' and 3', as they correspond to the carbon number of the pentose where the phosphate and hydroxyl (OH) group are located, which join in a phosphodiester bond.
