SIMULASI IDENTIFIKASI DAERAH CODING PADA DEOXYRIBONUCLEIC ACID DENGAN MENGGUNAKAN DISCRETE FOURIER TRANSFORM
Abstract: Deoxyribonucleic
acid (DNA) is a genetic substance that brings heredity factor. DNA consist of
four bases, which are adenine, timine, guanine, and citosine. Each base is
symbolized by A, T, G, and C. There are coding and noncoding regions in DNA
data. Coding region (called exon) is a DNA region that’s useful to describe
heredity factor. Many methods can be used to determine coding region in DNA
data, one of them is by using Discrete Fourier Transform (DFT). Simulation
using DFT is performed by entering the algoritm similarities into Matlab language
program. The purpose of simulation are to predict exon length, to get the value
of optimized spectral and
to get the
value of exon
total power spectral.
Optimized spectral is useful
to identify exon position in DNA data.
The results of simulation
reveal that the
total power spectral value of exon is proportional to N-point DFT value
for each DNA sequence and the optimized spectral value of DNA is also
proportional to quantity of exon bases and exon length. Optimized spectral
value reaches maximum for more quantity of exon bases and more length of exon
than when optimized spectral value reaches minimum.
