Hi, in the question we are asked which of the following describes a means of performing genome annotation? so we are talking about genome annotation, okay? annotation.
00:12
So first let's see what is genome annotations and then we can find the options.
00:17
So they are given four options, okay? and then we can find the correct option.
00:21
So a general and literal meaning of annotation means explanation or a comment.
00:26
Explanation or a comment added to a already existing text okay so this is done to explain the particular available content better okay so that is the meaning of annotation so what what is genome annotation what is genome annotation it is the process of identifying okay identifying functional elements identifying functional elements along the sequence of genome okay for genome sequence for a given genome sequence we have to identify the functional element okay why it is necessary because when a dna is sequenced it generates okay it generates sequences of unknown function, okay, it generates sequences of unknown function.
01:26
So that is the reason we have to do genome annotation to know the function, okay, to know the function of a particular sequence, okay? so basically when genome is sequenced, it must be annotated to bring a logical information about its structural and functional features, okay, structural and functional features.
01:52
Okay functional information okay we have to annotate the gene in order to identify this okay so we have three steps for doing this okay first is recognizing piece of genome that do not encode for protein do not encode for proteins okay first step next is recognizing essentials of genome called us gene predicting, okay, gene predicting, and third is recognizing organic information about these elements, okay, organic information about these elements...
