- The DNA is held together by proteins called histones which help to keep the shape of the chromosomes. Genes Genes are the functional regions of the genome, they are a blueprint for all the useful bits and pieces in our cells. Genes contain the information that tells the cell how to make a particular protein.NA is an extremely long chain of molecules that contains all the information necessary for the life functions of a cell. The individual molecules that make up DNA are called nucleotides.

Aprovocative A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together (Figure 4-3).As we saw in Chapter 2 (Panel 2-6, pp.NA was known to be a long polymer composed of only four types of subunits, which resemble one another chemically. Early in the 1950s, DNA was first examined by x-ray diffraction analysis, a technique for determining the three-dimensional atomic structure of a molecule (discussed in Chapter 8).

- Making the world better, one answer at a time. the rungs are made up of two nitrogen containing bases that are connected to each other by two or three hydrogen bonds. this is how a DNA looks like when untwisted NCB stands for nitrogen containing base and H stands for Hydrogen. |NCB-HH-NCB|.|NCB-HH-NCB|. ---   The pairs are guanine and cytosine (G-C), or adenin … e and thymine  (A-T). The rungs of the dna ladder are made of alternating sugars and  phosophate groups. 108 people found this useful.

DNA molecules are long — so long, in fact, that they can't fit into cells without the right packaging. To fit inside cells, DNA is coiled tightly to form structures we call chromosomes.

Life Under the genetic code, RNA strands are translated to specify the sequence of amino acids within proteins. These RNA strands are initially created using DNA strands as a template in a process called transcription. Within cells, DNA is organized into long structures called chromosomes. During cell division these chromosomes are duplicated in the process of DNA replication, providing each cell its own complete set of chromosomes.

Molecular anthropology There are two continuous linkage groups in human that are carried by a single sex. The first is the Y chromosome, which is passed from father to son. Anatomical females carry a Y chromosome only rarely, as a result of genetic defect. The other linkage group is the mitochondrial DNA (mtDNA).itochondrial DNA offers another advantage over autosomal DNA. There are generally 2 to 4 copies of each chromosome in each cell (1 to 2 from each parent chromosome). For mtDNA there can be dozens to hundreds in each cell. This increases the amount of each mtDNA loci by at least a magnitude.

DNA molecule A DNA molecule (deoxyribonucleine acid) is made of two chains of several thousands of linked nucleotides. Each nucleotide consists of a phosphate group, a deoxyribose and a nitrogenous base (Fig. 1). The four nitrogenous bases that occur in DNA are: adenine (A) , guanine (G) , thymine (T) and cytosine (C) (Fig. 2).

DNA DNA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms.This includes animals, plants, protists, archaea and bacteria. DNA is in each cell in the organism and tells cells what proteins to make. Mostly, these proteins are enzymes.DNA is inherited by children from their parents. This is why children share traits with their parents, such as skin, hair and eye color.NA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms.

How are new DNA molecules made? DNA tells a cell how to make proteins through the genetic code. Both DNA and proteins are long molecules made from strings of shorter building blocks. While DNA is made of nucleotides, proteins are made of amino acids, a group of 20 different chemicals with names like alanine, arginine, and serine.

Describe the Basic Shape & Purpose of the DNA Molecule The DNA molecule is shaped like a ladder that is twisted into a coiled configuration called a double helix. The nitrogen bases form the rungs of the ladder and are arranged in pairs, which are connected to each other by chemical bonds.he DNA molecule carries the genetic code for building organisms. Contained in its intricate structure is the complex biological information needed to produce the proteins that make up the bodies of all living things.

- A chromosome (from ancient Greek: χρωμόσωμα, chromosoma, chroma means color, soma means body) is a DNA molecule (wrapped around Histone Protein in Eukaryotes) with part or all of the genetic material of an organism. Chromosomes are normally visible under a light microscope only when the cell is undergoing the metaphase of cell division.
