Genetic information, variation and relationships between organisms 0.0 / 5 ? BiologyDNA, genetics and evolutionA2/A-levelAQA Created by: EloiseCreated on: 17-06-20 14:01 Genomics Study of a whole set of genetic information in the form of DNA base sequences that occurs in the cells of organisms of a particular species. 1 of 11 Genome Is the complete set of genetic information within an organism/cell. 2 of 11 Genetic code Is universal because the same specific base triplet codes for the same amino acids in all living things. 3 of 11 Non-coding DNA Fills the gaps between genes, not junk, carries out regulatory functions. 4 of 11 Introns Don't code for amino acids, found in eukaryotic cells, removed during protein synthesis. 5 of 11 Exons Genes that code for amino acids. 6 of 11 Non-overlapping Each base is part of one codon, it is not part of the one before or after. 7 of 11 Gene A sequence of bases that code for polypeptides/functional RNA. 8 of 11 Amino acid 3 bases (triplet), also called a codon. 9 of 11 Degenerate One amino acid can be coded for by more than one triplet code. 10 of 11 Storing DNA in eukaryotic cells - Contains linear DNA molecules (chromosomes). - Really long. - Wound around histone proteins that support DNA. 11 of 11
