A branch of biology that deals with the heredity and variation of organisms. It studies how living things receive common traits from previous generations.
INTRODUCTION Gregor Johann Mendel – Father of Modern Genetics. He studied approximately 29000 pea plants to demonstrate inheritance of traits following certain laws. For seven years, Mendel bred pea plants and recorded inheritance patterns in the offspring. He studied seven characteristics in the garden pea. WHY A PEA PLANT Flower structure of pea plant ensured …
A vector is a DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell, where it can be replicated or expressed. Cloning vector is a small DNA molecule capable of self-replication inside the host cell. Cloning vector is used for replicating donor DNA fragment within host cell. Vectors can replicate …
A – DNA Much wider and flatter. Right handed helix. major grooves: Narrow and deep minor grooves: wide and shallow Glycosidic bonds – anti-form 11 base pair B – DNA Solid central core. Right handed Major groove: wide and narrow Minor groove: narrow and deep Glycosidic bond – anti-form 10 base pair Z – DNA …

Structure formed in nucleic acids by sequences that are rich in Guanine. Backbone represent by tube. Likewise, Cytosine can form C-G-C. They are less stable than double helixes due to fact that the 3 negatively charged backbone strands in triple helix results in increased electrostatic repulsion.

1905-2002 By Erwin chargaff It states that in all DNA, Pyrimidines and Purines must have 1:1 Adenine : Thymine Cytosine : Guanine i.e., the amount of adenine = amount of thymine similarly, the amount of cytosine = amount of guanine. It indicated that DNA is symmetrical. (A) Double bond (T) and (C) triple bond (G) …

In 1953 They conducted that: Polynucleotide chain of DNA has a regular helix, Helix has a diameter of about 20 Ao, and Helix makes a full turn at every 34 A0 along its length and contains 10 nucleotides per turn, because per internucleotide distance is 3.4 Ao . To provide thermodynamic stability they thought over …
Deoxyribonucleic acid DNA as a genetic material First extracted from, nuclei in 1870 Named “nuclein” Chemical analysis: determined DNA as a weal acid and rich in Phosphorous Furthered named DNA, as lot of information provided by name: Deoxyribonucleic acid Contains sugar (deoxyribose) Weakly acidic Found in Nucleus Only four different subunits makes up DNA Chromosome …
1865 : Gregor Mendel tells about the importance of “Factor” inheritance in pea plant. 1944 : Avery, Macleod and McCarty conduct experiment that shows DNA, not protein, causes bacterial transformation. 1953 : article by Watson and Crick in nature describes the structure of DNA for which they later win the Nobel prize. 1956 : Human …
•In prokaryotic cells, reproduction is simple, because prokaryotic cells possess a single molecule. binary fission takes place in prokaryotic cells of simple single-celled organisms such as bacteria. •In eukaryotic cells, multiple chromosomes must be copied and distributed to each of the new cells, and so cell reproduction is more complex. •Cell division in eukaryotes takes …
•We all possess genes that influence our lives in significant ways. •Genes affect our height, weight, hair color, and skin pigmentation. •They influence our susceptibility to many diseases and disorders and even contribute to our intelligence and personality. •Genes are fundamental to who and what we are. •Even though the science of genetics is not …
