Abstract

Chromosomes become an important substance for an organism because they contain information useful for cell regulation and as a hereditary agent. The character of an organism is determined by genes located on chromosomes. Changes in chromosomes will have a significant influence on the evolution of a species. One of the factors that influence changes in chromosomes is mutation. Mutation is a form of defense of an organism in the face of the changing state of nature. Neacomys diversification is caused by gene fusion events, translocations, amplications, and constitutive heterochromatin (CH). In the family Crenuchidae genus Caracidium there was a revision in the diversification of chromosomes 2n of 50 chromosomes composed of 32 metacentric + 18 sub-metacentrics. This is due to differences in the number of rDNA sites, heterochromatin blocks, number of B chromosomes and the size of sex chromosomes, as well as repeated DNA dynamics on chromosomes observed among species forming diversification and chromosomal speciation. In the boidae family reptile class there was a fusion of chromosomes which resulted in the conclusion that the kariotype configuration in snakes is currently the clade of primitive Neotropic snakes.

Abstract

A metabolic disorder appears when unusual chemical reactions impair the metabolism process in the body. This condition affects how the body distributes and processes macronutrients, including protein, lipids, and carbohydrates. Transcription Factor 7 Like 2 (TCF7L2) is a 217,460 bp gene, found in chromosome 10q25, and encodes the High Mobility Group (HMG) box with a role in the Wnt signaling pathway. The Wnt signaling pathway involves several processes during development, healthy homeostasis, and illness. The reactions that follow the pathway's activation regulate both proliferation and differentiation. Single Nucleotide Polymorphism (SNP) in the TCF7L2 gene has been linked to a variety of metabolic disorders incidence. SNP rs11196205 was found to have a significant association with type 1 and type 2 diabetes mellitus, gestational diabetes mellitus, glucose homeostasis, obesity-related parameters, and renal function. Mechanism SNPs causing the metabolic disorder are still unexplained, but SNPs are suspected to affect transcription and splicing processes. SNPs of TCF7L2 genes are reported to affect proinsulin conversion to insulin, decrease incretin hormone production, and decrease insulin sensitivity throughout the body. It can conclude that the screening for the SNP can be a sign of metabolic process abnormalities, especially in diabetes Mellitus.

Abstract

The fingerprint pattern (dermatoglyphics) of each individual is not the same. Fingerprint patterns are often used as an identification tool in criminal cases and disease diagnosis. Fingerprint patterns for health diagnosis are usually diseases caused by genetic factors, for example hypertension. The purpose of this study was to describe the characteristics of fingertip dermatoglyphics of hypertension patients. The research sample was 60 people consisting of 30 people with hypertension who visited the DR. M. Djamil Padang and controls 30 non-hypertension (normal) people from Biology FMIPA UNP students. Simple random sampling. The research variables are tendril patterns on the fingertips. The Chi-square test was used to analyse the tendril pattern data of hypertension patients. The results showed that the arch fingerprint pattern is a unique character in hypertensive patients.
