Consider the following segment of DNA:
5'-...ATGCCAGTCACTGACTTG...-3'
3'-...TACGGTCAGTGACTGAAC...-5'
If the lower strand of DNA serves as the template transcribed into mRNA, how many peptide bonds are present in the polypeptide fragment into which the mRNA is translated?

Understand the main divisions of genetics: Transmission genetics, Molecular genetics, and Population genetics.
Transmission genetics focuses on the inheritance of traits from one generation to the next, often using Mendel's laws as a foundation.
Molecular genetics studies the structure and function of genes at a molecular level, including DNA replication, transcription, and translation.
Population genetics examines the genetic composition of populations and how it changes over time due to factors like natural selection, genetic drift, and gene flow.
Recognize that 'Breeding genetics' is not a standard division of genetics, but rather a practical application of genetic principles in agriculture and animal husbandry.
