The DNA segments that carry this genetic information are called genes, and their location within the genome are referred to as genetic loci, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.
4 lut 2008 · If these best homologous DNA sequences are from different organisms, they are called orthologs (with some exceptions). If homologous sequences are within one genome, they are called paralogs . A special case of paralogy results from polyploidy.
23 mar 2016 · Yes, they do have distinct genes in general, but what you may see as different plants can also sometimes be clones. For example Quaking Aspen Trees which commonly grow in clonal colonies. If you had a massive database of genetic material from plants you would be able to trace it.
Four types of these bases compose both strands of DNA. Two of the bases, collectively called purines — Adenine (A) and Guanine (G) — contain two rings of carbon atoms. The other two, collectively called pyrimidines — Cytosine (C) and Thymine (T) — have only one ring of carbon atoms.
13 mar 2015 · The DNA in plant cells is found in the nucleus, the mitochondria and the chloroplasts. The latter two organelles are descendants of bacteria that were captured by a eukaryotic cell and have become endosymbionts. DNA is a coded set of instructions for making RNA.
The genotype of a plant is subdivided into genes, which are the hereditary units consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes, which results in changes in a gene, for example a flower color gene ...
With the exception of identical twins, each person's DNA is unique. DNA is made from base pairs which always come in the following combinations A-T, T-A, C-G and G-C. The order of these letters...
