Verified step by step guidance

Understand the concept of a molecular marker: It is a small segment of DNA that can be used to identify a particular sequence or location within a genome.

Recognize the unique properties of molecular markers: They are typically polymorphic, meaning they vary among individuals, which makes them useful for genetic mapping and studies.

Differentiate molecular markers from other options: Unlike fluorescent probes or proteins, molecular markers are DNA sequences that serve as landmarks in the genome.

Consider the applications of molecular markers: They are used in various genetic studies, including linkage analysis, population genetics, and breeding programs.

Review examples of molecular markers: Common types include microsatellites, single nucleotide polymorphisms (SNPs), and restriction fragment length polymorphisms (RFLPs).
