DNA

• DNA is made up of building blocks called nucleotides
• Nucleotides are composed of three parts - sugar, phosphate group, nitrogenous base
• Adenine always pairs with Thymine via hydrogen bonds
• Guanine always pairs with Cytosine via hydrogen bonds
• Genes are sections of DNA that code for proteins or RNA molecules.
• The sugar and phosphate form the backbone of the ladder and the bases form the rugs of the ladder
• A gene is a section of DNA that codes for a protein or RNA molecule
• Chromosomes are condensed structures made out of DNA molecules that contains the gene
• There are 2 sex chromosomes in each cell, one from each parent.
• Males have XY chromosomes
• Females have XX chromosomes
• There are 46 chromosomes in humans.
• Autosomal chromosomes does not determine the sex of the organism but rather carries genetic codes or genes
• Genes are sections of DNA arranged along the chromosomes
• Each gene is responsible for producing a specific protein that performs a particular function within an organism's body
• autosomes chromosomes carries the genes or codes for a specific trait
• Sex chromosomes determines your gender
