DNA‚ which stands for Deoxyribonucleic acid is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms. The main role of DNA molecules is the long-term storage of information. These nucleic acids consist of long chains if chemical units called nucleotides. Nucleic acids are information storage molecules that provide the directions for building proteins. Described by the DNA testing centre‚ Inc.‚ “DNA is found inside the chromosome

More than one celled organisms grow by way of mitosis and the cytoplasmic division of body cells. On the other hand‚ meiosis occurs only in germ cells‚ which are put aside for the formation of gametes (sperm and egg). Reproduction by meiosis allows for species survival and it increases genetic variability. The process‚ during which the germ cells are generated is called meiosis. It represents nature’s solution to the problem of chromosome doubling that would occur‚ if two diploid cells‚ i.e.

Looks Can Be Deceiving! • These meadowlarks look very similar yet they are not the same species. Definition of Species • A species is a group of interbreeding organisms that produce viable‚ fertile offspring in nature. • Members of a species will interbreed with one another but not other organisms outside of the species. (At least most of the time!) Macroevolution vs. Microevolution • Macroevolution is evolution on a scale of separated gene pools. • Macroevolutionary studies focus on change

world has and how it works. A process that is familiar is called pollination. Meaning pollen is transferred in plants; it enables fertilization and sexual reproduction (Russel et al‚ 2010). Pollen grains contain the male sperm‚ which are known as the gametes (sperm) to where the female gamest are carried in the carpel‚ which in this case the gymnosperms directly apply the pollen to the ovule itself (Russel et al‚ 2010). Pollination is a very important step in the history of reproduction of flowering plants

Nondisjunction occurs when either homologues fail to separate during anaphase I of meiosis‚ or sister chromatids fail to separate during anaphase II. The result is that one gamete has 2 copies of one chromosome and the other has no copy of that chromosome. (The other chromosomes are distributed normally.) If either of these gametes unites with another during fertilization‚ the result is aneuploidy (abnormal chromosome number) • A trisomic cell has one extra chromosome (2n +1) = example: trisomy
