Explanation:
Most of the DNA is found in the cell nucleus but a small amount of DNA can also be found in the mitochondria and it is called mitochondrial DNA. Mitochondrial DNA, unlike nuclear DNA, is inherited from the mother, while nuclear DNA is inherited from both parents.
The nuclear DNA is found within a compartmentalized area within the cell called the nucleus. Each DNA molecule must be packed very tightly and precisely. This super-packaged form of DNA is called a chromosome.
we can conclude that the correct answer is:
Answer:The location of DNA in eukaryotic cells is:Cell nucleus as nuclear DNA.Mitochondria as mitochondrial DNA.
Answer:
The duplication of a cluster of four Hox genes is equally likely as the duplication of a single Hox gene.
Explanation:
This comes from the definition of the parsimony principle, which is the action of choosing the simplest scientific explanation fitting the given evidence, meaning that all other elements are equal when evaluating the hypothesis. In biology the best hypothesis is the one that requires the fewest evolutionary changes.
Since three independent duplications of an individual Hox gene is in evolutionary terms, more complex than a single duplication or a cluster, then that hypothesis would be the most parsimonious.
Answer:
a. antigen
