Chromosomes.
Genes are segments of DNA. What makes one gene different from another is the order of its DNA bases. The specific arrangement of bases in a gene is the code or the instructions of how to make a particular protein. Proteins are what perform most of the functions that our body needs to grow and survive. DNA is found in the cell's nucleus and is the genetic information that is transmitted from a parent to a child. DNA resembles a twisted ladder, which is called a double helix. The steps of this ladder are made up of structures called bases. There are four different bases that make up the steps of the DNA Chromosomes, DNA and genes. The nucleus of a cell contains chromosomes chromosomes: Rod shaped bodies found in the nucleus of cells that contain genetic information (DNA). that carry genetic information. Most body cells have the same number of chromosomes, but this varies between speci The nucleus of a cell contains chromosomes, which carry genetic information in a long molecule called DNA. Genes are regions of DNA that carry the code to control a particular cell activity or the production of a particular protein. The nucleus of a cell contains chromosomes chromosomes: Rod shaped bodies found in the nucleus of cells that contain genetic information (DNA). that carry genetic information. Most body cells have the same number of chromosomes, but this varies between species A gene is a section of DNA which controls part of a cell's chemistry-particularly protein production. is a shorter region of DNA that carries the genetic code for a particular characteristic or cell activity. Nucleus, chromosome and gene. DNA molecules contain chemicals called bases. The nucleus of a cell contains chromosomes chromosomes: Rod shaped bodies found in the nucleus of cells that contain genetic information (DNA). that carry genetic information. Most body cells have the same number of chromosomes, but this varies between speci Chromosomes. Chromosomes carry hereditary, genetic information in long strings of DNA called genes. Humans have 22 numbered pairs of chromosomes and a single pair of sex chromosomes—XX in females and XY in males. Each chromosomal pair includes one inherited from the father and one from the mother.  Deoxyribonucleic acid (/diˌɒksiˌraɪbɵ.njuːˌkleɪ.ɨk ˈaesɪd/ ; ˈæSɪD) dna is a molecule that carries most of the genetic instructions used in the, development functioning and reproduction of all known living organisms and many. viruses Enzymes called DNA ligases can rejoin cut or broken DNA strands. Ligases are particularly important in lagging strand DNA replication, as they join together the short segments of DNA produced at the replication fork into a complete copy of the DNA template. They are also used in DNA repair and genetic recombination. DNA stands for deoxyribonucleic acid. It is DNA that carries the instructions that help dictate how an organism will grow and develop. DNA is found in the cell's nucleus and is the genetic information that is transmitted from a parent to a child. DNA resembles a twisted ladder, which is called a double helix. The steps of this ladder are made up of structures called bases. There are four different bases that make up the steps of the DNA double helix. DNA. DNA (or deoxyribonucleic acid) is the molecule that carries the genetic information in all cellular forms of life and some viruses. It belongs to a class of molecules called the nucleic acids, which are polynucleotides-that is, long chains of nucleotides. Each nucleotide consists of three components: A gene is a sequence of DNA that contains genetic information and can influence the phenotype of an organism. Within a gene, the sequence of bases along a DNA strand defines a messenger RNA sequence, which then defines one or more protein sequences. Enzymes called DNA ligases can rejoin cut or broken DNA strands. Ligases are particularly important in lagging strand DNA replication, as they join together the short segments of DNA produced at the replication fork into a complete copy of the DNA template. They are also used in DNA repair and genetic recombination.
