Dna and genes

DNA and RNA are nucleic acids that play essential roles in genetic coding but have different structures and functions. Learn their differences and roles here!

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

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).

DNA and RNA are nucleic acids present in all living cells. Learn more about the DNA, RNA and its differences.

Advances in technology have enabled researchers to sequence the large regions of repetitive DNA that eluded the Human Genome Project.

Human Genome Project - Genome Mapping, DNA Sequencing, Genomics: The International HapMap Project, genomics studies, the Entrez Genome database, and the BLAST software tool allow the study of genetic similarity and divergence among humans and between species. The influence of the genome on health has led to personalized medicine. CODIS and comparative DNA sequence analyses have revolutionized the fields of forensics and anthropology, respectively.

OK so I'm a bit confused. Does a chromosome consist of genes and do genes consist of DNA? What about the 23 pairs in sexual reproduction? I can't remember what the pairs consist of
