Life is a complex definition that biotechnology targets to manipulate and engineer this definition with genetic engineering techniques. Bacteria have been the very first organisms to live on Earth. They made their appearance 3 billion years ago in the waters of the first oceans. At first, there were only anaerobic heterotrophic bacteria (the primordial atmosphere …

Viruses as complex forms of life are a big threat for social health and can make a big pandemic like COVID19. RNA viruses generally have very high mutation rates compared to DNA viruses, because viral RNA polymerases lack the proofreading ability of DNA polymerases. The genetic diversity of RNA viruses is one reason why it …

DNA as a basic secret code of life created structure and function of the cells. Here are 4 interesting facts about DNA and chromosomes. DNA contains four building blogs: guanine, adenine, thymine, and cytosine. A single chromosome anywhere between 50 million and 250 million base pairs. There are around 3 million DNA bases in our …

DNA as a secret book of life is the central commander of life in the cell, but where is DNA Found? Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or …

Two important genetic definitions that are important in biotechnology class are allele and gene. What is the difference between a gene and an allele? The short answer is that an allele is a variant form of a gene. Explained in greater detail, each gene resides at a specific locus (location on a chromosome) in two …

DNA sequences are life codes in the cells that shape organism structure and function. The Australian lungfish has the largest genome of any animal so far sequenced. Siegfried Schloissnig at the Research Institute of Molecular Pathology in Austria and his colleagues have found that the lungfish’s genome is 43 billion base pairs long, which is …

DNA tests are one of the most money making products in biotechnology and biopharmaceuticals industries and today we have commercial products based on genetic and biotechnology definitions to answer this question: can DNA tell your age? Biological age can be calculated by measuring certain “biomarkers” that scientists know correlate with getting older — changes like …

Diploid and Haploid are two important genetic definitions in biotechnology courses. You should concentrate on deep meaning. Diploid describes a cell that contains two copies of each chromosome. … The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).
DNA conformation and structure is always in change . The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.
DNA is the basic fundamental of life of the cells. Without DNA, there is no protein, there is no RNA and there is no life. No, a person cannot live without DNA. DNA provides the body with the instructions to create necessary proteins. DNA is crucial in order to live, without it we would not …
