How are the mutations in a genome similar to printing a book? every letter in a book resembles the mutations in the genome. errors that appear in one copy can be copied to all other copies of the book. like printing errors, mutations always negatively affect the final product. just as a single book is printed at a time, a single mutation is read at a tim

Option B, errors that appear in one copy can be copied to all other copies of the book.

Explanation:

Genetic errors are very random as DNA replication is an accurate process but still there can be some mistake during the insertion of nucleoside bases.

If such errors are not corrected at the point of occurrence, then it can be replicated at a very fast pace through the entire genetic material thereby causing  serious consequences such as mutation, cancer etc.

Similarly in a book printing, a mistake which get unnoticed can be replicated in other books.

Hence, option B is correct

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
