During the process of chromosome replication, A genetic error occurs. As a result, a sequence of events occurs as described below. Event A. Protein with the new sequence of amino acids is produced. Event B: a DNA strand with an altered base sequence is formed. Event C:, A new inheritable trait is expressed in an organism. Event D, An mRNA strand with the new sequence of bases is synthesized. The usual order in which these events would occur is: 1. B-D-A-C. 2. B-D-C-A. 3. D-A-B-C. 4. D-C-B-A

Answer: 1. B-D-A-C.

Explanation: If a genetic error occurs during chromosome replication, it will lead to a series of events ranging from:

1) Production of a DNA strand with an altered base sequence.

2) Production of an mRNA strand with an altered base sequence during transcription. This is because mRNA is synthesized by copying the genetic message coded in the DNA.

3). Synthesis of a protein with an altered amino acid sequence during translation, and this eventually leads to

4). The expression of a new inheritable trait in the organism.
