Web8 de ago. de 2012 · In brief, a gene is actually a recipe that the cell uses to make a particular protein. Since most of a cell’s DNA is in the nucleus, the “recipe” stored in that gene must leave the cell’s nucleus in order to be turned into a protein. To do that, the “recipe” is copied by a molecule called messenger RNA (mRNA). Web1. specific enzymes give rise to specific genes. 2. enzymes regulate gene activity. 3. each allele codes for a single type of protein. 4. DNA is transcribed into RNA, which is …

Web11 de abr. de 2024 · Genetic code. The story of the genetic code is the story of biology and genetics in the 19th, 20th, and 21st centuries, as well as its promises and its perils. Oswald Avery in 1944, for example, proved that the genetic code — that DNA —was indeed the carrier of hereditary information, ending more than 80 years of productive … WebIn one of the simplest potential codes, each nucleotide in an DNA or RNA molecule might correspond to one amino acid in a polypeptide. However, this code cannot actually work, … polyp on gum tissue
How can one gene code for more than one protein? : r/biology
Web1 de mar. de 2024 · This results in one gene producing many similiar proteins, but all with potentially different or differentiated functions. These proteins are generally called Isoforms. Many genes should be thought of as not making a single protein, but making a family of protein isoforms. Some viral genes produce multiple proteins from a single piece of … Web9 de mar. de 2024 · genetic code, the sequence of nucleotides in deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) that determines the amino acid sequence of proteins. Though the linear sequence of nucleotides in DNA contains the information for protein sequences, proteins are not made directly from DNA. Instead, a messenger RNA … WebIt can happen that multiple genes can be translated to produce identical proteins in one species. In such cases, all gene products were historically often merged into a single UniProtKB entry and there are as many 'Name' tokens in the 'Gene names' subsection as the number of genes encoding the protein of interest, e.g. P68431 . shann family
