Meiosis
In this experiment we observed the procedure of miosis by looking at different slides. Meiosis is a procedure in which a diploid ( 2n ) parent cell is divided into four haploid ( n ) girl cells. The girl cells have half the figure of chromosomes as the parent cell. Meiosis chiefly occurs in sex…

Morality
Technology
Whether we are reading newspaper articles, surfing the Internet, or watching the news, we cannot avoid the challenges posed by new technology and scientific advancements. Genetic engineering and recombinant DNA, and their uses, are highly debated. People have diverse opinions influenced by factors like friends or family’s viewpoints, occupation, religion, environment, or media debates. However,…
DNA: Descriptions, Feutures and Purposes
Dna
Proteins regulate the structure ND function of all living organisms. 3. Humans contain 46 copies (23 pairs) of chromosomes in somatic cells. These copies are inherited from the mother and father. In those chromosomes, it is an estimated 20,000-25,000 human protein- coding genes. 4. This statement is an analogy to DNA extraction because DNA is…
The history of DNA

History
The history of DNA use for forensic cases already spans more than a decade. The first cases into which DNA evidence was brought in were in England. The first case of using DNA-related evidence in Arizona courts was the 1988 murder of Jennifer Wilson by Richard Bible near Flagstaff. Blood found on the back of…

Deoxyribonucleic acid is an indispensable portion of beings. It is the manager of many facets of the organic structure. The Deoxyribonucleic acid consists of a sugar base, phosphate and a nitrogen base. There are merely four N bases to take from. They are guanine, adenine, thymine and C. They are grouped under two groups: the…
Mitochondrial Dna And Its Sources Biology

When most people hear the acronym DNA, they instantly think of the familial stuff that exists within the karyon of their cells. However, there are two beginnings of DNA within most cells of the organic structure – one in the karyon, and another in the chondriosome. Although much about the familial stuff of chondriosome remains…

DNA, Deoxyribonucleic acid, is a double stranded, helical nucleic acid molecule which determines inherited structure of a protein. The “steps” are made of bases: adenine, guanine, cytosine, and thymine. The sides are sugar and phosphate molecules. Restriction enzymes are enzymes that cut DNA at restriction sites, leaving fragments blunt or sticky. The restriction fragments are…

1. Describe the structure of a nucleotide. A nucleotide is a sugar molecule that has 3 parts including a simple sugar, a phosphate group and a nitrogenous base. Nucleotides join together forming long chains, with the phosphate group of nucleotide bonding to the deoxyribose sugar of an adjacent nucleotide. 3. Explain why the structure of…
