These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes. Each gene stores the directions for making protein fragments, whole proteins, or multiple specific proteins.
The Biological function of DNA 1 DNA polymers direct the production of other polymers called proteins. A protein is one or more polymers of monomers called amino acids. ... 2 A chromosome consists of smaller segments called genes. ... 3 Each gene is further divided into three nucleotide subsegments called codons. ...
DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.

Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
Definition. A stop codon is a sequence of three nucleotides (a trinucleotide) in DNA or messenger RNA (mRNA) that signals a halt to protein synthesis in the cell. There are 64 different trinucleotide codons: 61 specify amino acids and 3 are stop codons (i.e., UAA, UAG and UGA).
codon AUGThe codon AUG is called the START codon as it the first codon in the transcribed mRNA that undergoes translation. AUG is the most common START codon and it codes for the amino acid methionine (Met) in eukaryotes and formyl methionine (fMet) in prokaryotes.
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
The DNA code is really the 'language of life. ' It contains the instructions for making a living thing. The DNA code is made up of a simple alphabet consisting of only four 'letters' and 64 three-letter 'words' called codons.
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
Only the tRNA carrying the next amino acid in the polypeptide chain has the anticodon that binds to the appropriate location on the mRNA. This system ensures that amino acids are added to the chain in the correct order.
DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using 'T' as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'.
The molecular structure of DNA. In order to understand the biological function of DNA, you first need to understand its molecular structure. This requires learning the vocabulary for talking about the building blocks of DNA, and how these building blocks are assembled to make DNA molecules.
DNA is well-suited to perform this biological function because of its molecular structure, and because of the development of a series of high performance enzymes that are fine-tuned to interact with this molecular structure in specific ways . The match between DNA structure and the activities of these enzymes is so effective and well-refined that DNA has become, over evolutionary time, the universal information-storage molecule for all forms of life. Nature has yet to find a better solution than DNA for storing, expressing, and passing along instructions for making proteins.
The nucleotide monomers in a DNA polymer are connected by strong electromagnetic attractions called phosphodiester bonds. Phosphodiester bonds are part of a larger class of electromagnetic attractions between atoms that chemists refer to as covalent bonds.
The English language has a 26 letter alphabet. In contrast, the DNA “alphabet” has only four “letters,” the four nucleotide monomers. They have short and easy to remember names: A, C, T, G. Each nucleotide monomer is built from three simple molecular parts: a sugar, a phosphate group, and a nucleobase.
Each time nucleotides are bound together, a water molecule is removed (or “lost”) through a process called dehydration synthesis. Many molecules rely on dehydration synthesis to assist with forming polymers. A diagram showing how dehydration synthesis is used to make a string of DNA.
One strand runs in a 3' to 5' direction while the other runs in a 5' to 3' direction . The nucleotides forming each DNA strand are connected by noncovalent bonds, called hydrogen bonds. Considered individually, hydrogen bonds are much weaker than a single covalent bond, such as a phosphodiester bond.
DNA is the information molecule. It stores instructions for making other large molecules, called proteins . These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.
If the protein coat of a virus that infects a bacterium is labeled with radioactive sulfur and the DNA of the virus is labeled with radio active phosphorus, over time. only the phosphorus will be found inside the bacterium.
A cell of the pancreas would specialize in producing insulin, among other functions, while a muscle cell would specialize in the production of the protein myosin, this means that. A) Pancreas and muscle cells have the genes for both insulin and myosin active.
A) Radioactively labeled protein was found in the bacteria, not in the virus coats.
Periosteum covers the outer surface of a bone and it contains osteoblasts, osteoclasts, and osteochondral progenitor cells. Endosteum lines the internal surfaces of all cavities within bones and contains osteoblasts, osteoclasts, and osteochondral progenitor cells.
consists of specialized cells called chrondroblasts that produce a matrix surrounding themselves
Chondroblasts create the major component, the extracellular matrix, of the cartilage.
Trabeculae are interconnecting rods or plates in spongy bone, which bear weight and help bones resist bending and twisting.
Lamellar bone: the collagen fibers lie parallel to one another, but at an angle to the collagen fibers in the adjacent lamellae. A mature bone
The perichondrium (from Greek περί (peri 'around') and χόνδρος (chondros 'cartilage')) is a layer of dense irregular connective tissue that surrounds the cartilage of developing bone. It consists of two separate layers: an outer fibrous layer and inner chondrogenic layer.
