Basically, a gene is used to build a protein in a two-step process: 1  Step 1: transcription! Here, the DNA sequence of a gene is rewritten in the form of RNA. 2  Step 2: translation! In this stage, the mRNA is decoded to build a protein (or a chunk/subunit of a protein) that contains a specific series of amino acids.
In linguistics, a marker is a free or bound morpheme that indicates the grammatical function of the marked word, phrase, or sentence.More characteristically, markers occur as clitics or inflectional affixes. In analytic languages and agglutinative languages, markers are generally easily distinguished.In fusional languages and polysynthetic languages, this is often not the case.or example, in Latin, a highly fusional language, the word amo (I love) is marked by suffix-o for indicative mood, active voice, first person, singular, present tense. Analytic languages tend to have a relatively limited number of markers. Markers should be distinguished from the linguistic concept of markedness.
A genetic marker is defined as a specific gene or DNA sequence that produces a detectable trait with a known location on a chromosome and that can be used to study family and population, identification of cells, species or individual. Introduction:
