Which of the following mutations would most likely affect a person's offspring? a. a mutation in blood cells b. a mutation in nerve cells c. a mutation in lung cells d. a mutation in sex cells

The correct answer is option D. a mutation in sex cells.

Explanation:

Sexual reproduction is the process in which new organisms are produced from the fusing or fertilization of the nucleus of a male sex cell and a female sex cell. Sex cells are also known as gametes.

Germinal mutations are those that occur in the egg or sperm cells and therefore can be passed on to the organism's offspring.

Mutation in A DNA that takes place in sex cells can be passed to offspring through sex cells. It can lead to genetic disorders such as sickle cell anemia.

Thus, the correct answer is option D.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation
