Basically proteins are made up of combination of 20 different amino acids in long chains of polypeptides that’s why scientists take them as the most complex structure and considered them the hereditary material.
Long stands of double helical DNA can fit into the nucleus of a single cell because DNA is specially packaged through a series of compaction events to fit easily within cell nuclei.Even though the length of DNA per cell is about 100,000 times as long as the cell itself, it only takes up only about 10 percent of the cell’s volume.The DNA molecule, in order to condense, wraps itself around.
DNA testing has overthrown the way police collect evidence in a number of criminal cases, especially rape and murder and consequently had a large impact on many past cases. However there are many disadvantages to DNA testing, such as a challenge of accuracy, the costs of DNA testing and the possibl.
Introduction: what do we mean by inheritance in biology. when was DNA discovered who are the main scientists that described it, what were we thinking carrying inheritance before that. Paragraph 1 describe chromosomes, genome, DNA and what is replication briefly Paragraph 2: why are proteins important in your body and how to make a protein from DNA.
