Basic Genetics

DNA is a data storage molecule that lives in your cells. If your genome is a recipe book, then chromosomes are the chapters, and genes are the recipes.

DNA, genes and chromosomes provide an instruction manual for your body to form and function.

The number of genes in living organisms, humans, animals, flora does NOT correlate with intelligence. Some plants have more genes than humans.

The position on a CHROMOSOME where it separates during cell division; a structure of noncoding DNA (DNA that does not convey genetic information)When the cell divides the strands of the chromatids migrate in opposite directions (pull apart) at the centromere. In a photomicrograph, the centromere appears as an indented, waistlike area on the chromosome. Geneticists use the centromere’s position, along with other chtrstcs of the chromosome, to match them into their pairs when creating…

This picture shows the organization of chromatin including DNA's double helix structure and how DNA winds around core particles to form nucleosomes. From there, the DNA continues to wind upon its self until a chromosome is created. The function of genes in DNA is to code for the creation of proteins to be used in the body. A genome is all the genes one person has. For example, the human genome is approx. 30-35,000 genes. (Picture obtained from McGraw-Hill Connect).

🧬 Back to Basics: Genes, Chromosomes, & Inheritance Patterns 🧬 Did you know our genes carry the blueprint for human development and function? Packed into 46 chromosomes (44 autosomes & 2 sex chromosomes), they shape everything from physical traits to health conditions. 🧠 Mendelian Inheritance Patterns: 👶 Autosomal Dominant (AD): Only 1 mutated gene is needed to pass on conditions like neurofibromatosis & polycystic kidney disease. Kids have a 50% chance of inheriting the condition if a…

Every human has about 100 trillion meters of DNA coiled tightly in their cell nuclei. In other words, each of us has enough DNA to go from here to the Sun and back more than 300 times. All of that DNA is tightly packaged into chromosomes in a complex series of coils and loops. These packaging mechanisms, and the experiments that led to their discovery, provide insight into the chromatin of eukaryotic cells.

Chromosomes are bundles of tightly coiled DNA located within the nucleus of almost every cell in our body. Humans have 23 pairs of chromosomes.

To fit into cells, the DNA double helix is wrapped up around histone proteins and then coiled up further into into chromosomes. In eukaryotic cells, chromosomes are found in the nucleus. Mitochondria...
