WebMany nucleotides form each gene. A gene is a small section of genetic code in the DNA of a chromosome. Each gene codes for a particular sequence of amino acids. in order to … WebMost codons specify an amino acid. Three "stop" codons mark the end of a protein. One "start" codon, AUG, marks the beginning of a protein and also encodes the amino acid methionine.

A portion of a DNA molecule that specifies a single functional unit is called a gene; different genes have different sequences of bases. Within cells, the long strands of DNA form condensed structures called chromosomes.
WebIn molecular biology and genetics, transcriptional regulation is the means by which a cell regulates the conversion of DNA to RNA ( transcription ), thereby orchestrating gene activity. A single gene can be regulated in a range of ways, from altering the number of copies of RNA that are transcribed, to the temporal control of when the gene is ... WebMay 21, 2005 · The discovery of the double-helix structure of the DNA molecule opened the floodgates for scientists to examine the code embedded within it. Now, more than half a century after the initial discovery, the DNA code has been deciphered—although many of its elements are still not well understood. What has been found has profound implications ...
WebAboutTranscript. There are different types of genetic mutations that can occur in a cell. Point mutations involve the replacement of one base with another.Frame-shift mutations occur when a base is added or removed from the sequence. Non-sense mutations create a stop codon, which can prevent the protein from being produced entirely, while ...
