Fish and Humans: Homologus Structure

The appearance of people and fish is not closely related. Most people do not see how we share the same characteristics as fish, but scientists know that these two species have homology. Homology has a similar structure and having a similar gene indicates that the species is from a common ancestor but does not indicate that these features are identical. Humans and fish are related to the chord line. Because humans share the homology of fish.

The closest human LRRK2 human homolog is LRRKl on chromosome 15q 26 (70% homology of Roc, COR and MAPK domains). Since Lrrk 2 has several specific repeating structures not present in the Lrrk 1 homolog, the difference between the two proteins lies mainly in their N-terminal tissues. Because C. elegans and Drosophila melanogaster have only one LRK-1 gene, phylogenetic analysis showed that LRRK2 is derived from gene duplication. Therefore, in vertebrates, Lrrk1 and Lrrk2 may have functional activities that are similar, but not overlapping. Enhancement of sequencing does not reveal the pathogenic LRRK1 mutation in familial Parkinson's disease

Human cells have 23 different chromosomes. Your somatic cells (also known as somatic cells) contain two copies of each chromosome for a total of 46 chromosomes. Two copies of each chromosome are called homologous chromosomes or homologs. Homologous chromosomes are similar in shape and size and have similar genetic information. You received a homolog from each of your mothers and you received another homolog from your father. If the cell contains two homologs of each chromosome, it is called a diploid.

Not all cells are diploid. In the life cycle of humans and other animals, gametes - egg cells and sperm cells - are haploid. Haploid cells contain only one homolog of each chromosome. The fusion of two haploid gametes forms a diploid fertilized egg. The fertilized egg is a fertilized egg cell, the first cell of a new individual. The haploid ensures that when the egg fuses with the sperm, the resulting fertilized egg contains the characteristic diploid chromosome number of the organism. Down syndrome occurs in all ethnic groups of the same frequency, with about 1 in 1,000 children. It is more common among older mothers. The incidence of mothers under 30 is only 1 out of 1,500 infants and the incidence of 750 infants between 30 and 35 years old mothers has doubled. Among mothers over the age of 45, the risk is as high as one out of 16 births.

Under the microscope, you can see the crossover, cross-shape structure where the homologs are linked to each other. At least one is required for each cognate pair since the cross-maintenance homologues are ligated together after the association complex has been degraded. Multiple intersections (up to 252525!) Are common for each homolog pair. After crossover, the mitotic body begins to capture the chromosome and moves them towards the center of the cell (medium plate). This may seem like familiar from mitosis, but there is a turning point. Each chromosome attaches only to the microtubule from one pole of the spindle, and the two paired homologs bind to microtubules from the opposite pole. Therefore, in metaphase I, homologous pairs, rather than individual chromosomes, are placed on the mid-plate for separation.
