Two offspring cells are most likely to inherit which one of the following from the parent cell?
a. A change in a nucleotide in mRNA
b. A change in a nucleotide in tRNA
c. A change in a nucleotide in rRNA
d. A change in a nucleotide in DNA
e. A change in a protein

Verified step by step guidance

Understand that inheritance refers to the transmission of genetic information from a parent cell to its offspring cells during cell division.

Recall that DNA is the molecule that stores genetic information and is replicated before cell division, ensuring offspring cells receive the genetic material.

Recognize that changes in mRNA, tRNA, rRNA, or proteins are not directly inherited because these molecules are synthesized anew in each cell and are not passed on as genetic material.

Identify that a change in a nucleotide in DNA (a mutation) can be passed on to offspring cells because DNA replication copies this change into the daughter cells.

Conclude that the most likely inherited change from the parent cell to offspring cells is a change in a nucleotide in DNA.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Genetic Material and Heredity

DNA is the primary genetic material that carries hereditary information passed from parent to offspring. Changes or mutations in DNA can be inherited by daughter cells during cell division, ensuring genetic continuity.

RNA Types and Their Roles

mRNA, tRNA, and rRNA are different types of RNA involved in protein synthesis but are not typically inherited by offspring cells. These RNAs are synthesized anew in each cell and do not carry genetic information across generations.

Mutations and Their Inheritance

Mutations refer to changes in nucleotide sequences. Only mutations in DNA can be passed on to offspring cells, while changes in proteins or RNA molecules are transient and not inherited during cell division.
