Genetics, Diseases, and Nanotechnology: Exploring Key Concepts
Genome
The set of genes from one species is arranged on corresponding chromosomes. The height of the chromosome also corresponds (map of genes).
Gamete
A reproductive cell that has half the number of chromosomes (23 chromosomes). Eggs and sperm are gametes.
Centromere
The point where a chromosome divides into two during cell division.
Node
A crossroads of investigation.
Purist
A person who strives for perfection.
Genomic Sequence
A set of sorted genes.
Pseudonamuts
An imitation of a mammoth.
DNA
DNA is a molecule

Echolocation
Echolocation is a biological or technological process that involves emitting sound waves and listening to the echoes that bounce back off objects in the environment to determine their location, distance, and shape. In biology, the use of echolocation by animals has been well documented for centuries. Ancient Greeks, for example, observed bats using echolocation to navigate and find food in the dark.
Principle of Echolocation

Diagnostic Imaging Methods
X-rays
Radiation uses X-rays, which are capable of printing on photographic plates. The problem is that the compact structures, like bones and cartilage, do not allow X-rays to pass through, while muscles, skin, and soft tissues show contrast. X-rays are used in orthopedic surgery, lung cancer diagnosis, and to visualize some tumors.
CT (Computed Tomography)
CT scans utilize X-rays and create images at different levels to achieve a three-dimensional representation. This helps

Introduction to Extracellular Matrix (ECM)
The ECM is a complex network of macromolecules that acts as “cement” between cells in biological tissues. It forms part of highly specialized structures like cartilage, tendons, and bones. Beyond its supportive function, the ECM regulates the behavior of cells in contact with it, influencing their differentiation, development, migration, and shape. The ECM is produced by specialized cells called connective tissue cells.

TISSUE: Introduction: ECM is a complex network of macromolecules that acts as “cement” between the universal biological cells, as part of highly specialized structures: cartilage, tendons, bones, etc. This function supports the ECM’s role in regulating the behavior of cells that contact it, influencing their differentiation, development, migration, and shape. The ECM is produced by ECM-producing cells called connective tissue, connective, or supportive cells.
