Question

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

Answer 1

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

Step-by-step 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

Answer 2

"Errors that appear in one copy can be copied to all other copies"
This is because errors are randomly generated, just like mutation, however, they have the ability to be passed down from one book to another if the second is copied from the first. The same goes for mutations. Please note, mutations are not always negative and can help in the survival of the species when selection pressures change.
