Multiple Choice
In an overview of DNA replication, what is the main goal of DNA replication in a cell?
A
To repair damaged DNA by removing thymine dimers caused by UV light
B
To increase genetic variation by exchanging segments between homologous chromosomes
C
To translate the genetic code into a polypeptide chain at the ribosome
D
To produce two identical DNA molecules so each daughter cell receives a complete copy of the genome
Verified step by step guidance1
Understand that DNA replication is a fundamental process that occurs before cell division to ensure genetic information is accurately passed on.
Recognize that the main goal of DNA replication is to create two identical copies of the DNA molecule from the original DNA strand.
Know that this process ensures each daughter cell receives a complete and exact copy of the genome, maintaining genetic consistency across cells.
Differentiate DNA replication from other processes such as DNA repair (which fixes damage), genetic recombination (which increases variation), and translation (which produces proteins).
Conclude that the primary purpose of DNA replication is to produce two identical DNA molecules so that each daughter cell inherits a full set of genetic instructions.
