WebOne of the definitions of a gene is as follows: a segment of deoxyribonucleic acid (DNA) carrying the code for a specific polypeptide. Each molecule of messenger RNA (mRNA) … WebGenes and Chromosomes. 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.
WebThus, a single gene, or transcription unit, can code for multiple proteins or other gene products, depending on how the exons are spliced back together. In fact, scientists have estimated that there may be as many as 500,000 or more different human proteins, all coded by a mere 20,000 protein-coding genes. WebSep 23, 2024 · A set of three nucleotides called a codon carries the information to make one subunit of a protein, an amino acid. One codon codes or has the sequence for one amino acid. ...

WebNov 2, 2008 · Human genes typically contain several "exons," or DNA sequences that code for amino acids, the building blocks of proteins. A single gene can produce multiple protein sequences, depending on which exons are included in the mRNA transcript, which carries instructions to the cell's protein-building machinery. WebIn addition to the above answers, one needs to first understand the difference/relationship between a Gene and the genetic code. The genetic code is written in triplets (3 nucleotides) and one triplet of nucleotides codes for one amino acid (a.a) except the Stop "triplets" or codons(UAA, UAG, UGA in nuclear DNA). Now since one protein/polypeptide is made …
WebThe genome of an organism is inscribed in DNA, or in some viruses RNA. The portion of the genome that codes for a protein or an RNA is referred to as a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.
WebNov 22, 2024 · The different versions of a protein can result in different observable characteristics (i.e. different phenotypes). Each cell in your body has two copies of each gene (one inherited from your mother and one inherited from your father).
