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.
In grammatical analysis, most phrases contain a key word that identifies the type and linguistic features of the phrase; this is known as the head-word, or the head. The syntactic category of the head is used to name the category of the phrase; for example, a phrase whose head is a noun is called a noun phrase.
