Most genes contain the information needed to make functional molecules called proteins. (A few genes produce regulatory molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression. Show
During the process of transcription, the information stored in a gene's DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. Both RNA and DNA are made up of a chain of building blocks called nucleotides, but they have slightly different chemical properties. The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm. Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm. The mRNA interacts with a specialized complex called a ribosome, which "reads" the sequence of mRNA nucleotides. Each sequence of three nucleotides, called a codon, usually codes for one particular amino acid. (Amino acids are the building blocks of proteins.) A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time. Protein assembly continues until the ribosome encounters a “stop” codon (a sequence of three nucleotides that does not code for an amino acid). The flow of information from DNA to RNA to proteins is one of the fundamental principles of molecular biology. It is so important that it is sometimes called the “central dogma.” Read Online (Free) relies on page scans, which are not currently available to screen readers.

Published quarterly, the journal explores the traditional arenas of rhetorical investigation including executive leadership, diplomacy, political campaigns, judicial and legislative deliberations, and public policy debate. Critical, analytical, or interpretive essays that examine particular instances of symbolic inducement in any historical period are welcome. Of special interest are manuscripts that explore the nexus of rhetoric, politics, and ethics–the worlds of persuasion, power, and social values as they meet in the crucible of public debate and deliberation. Publisher Information Since its founding in 1947, the mission of the Michigan State University Press has been to be a catalyst for positive intellectual, social, and technological change through the publication of research and intellectual inquiry, making significant contributions to scholarship in the arts, humanities, sciences, and social sciences. Rights & Usage This item is part of a JSTOR Collection. Which feature of Model 1 best illustrates how biological information is coded in a DNA molecule quizlet?Which feature of model 1 best illustrates how biological information is coded in a DNA sequence? The LINEAR sequence of the base pairs.
Which feature illustrates how biological information is coded in DNA molecule?DNA encodes information through the order, or sequence, of the nucleotides along each strand. Each base—A, C, T, or G—can be considered as a letter in a four-letter alphabet that spells out biological messages in the chemical structure of the DNA.
What determines the code or information of a DNA molecule quizlet?DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

Monomers are joined by a covalent bond, and a water molecule is produced.
