DNA replication is a biological process that occurs in all living organisms and copies their DNA; it is the basis for biological inheritance. The process starts when one double-stranded DNA molecule produces two identical copies of the molecule. The cell cycle (mitosis) also pertains to the DNA replication/reproduction process. The cell cycle includes interphase‚ prophase‚ metaphase‚ anaphase‚ and telophase. Each strand of the original double-stranded DNA molecule serves as template for the production

A DNA strand contains a complete representation of everything about our physiology. It also contains instructions on how to form our body by repeated divisions of a single cell. Each cell needs to know when it should‚ split into two‚ split into different kinds of cell for tissue differentiation. Cells also need to know when to stop growing because the body or organ is mature‚ and when it needs to replace tissue lost by injury. All of that is encoded into one molecule. So in other words the benefit

one thing that unites us all‚ DNA. DNA‚ standing for Deoxyribonucleic Acid‚ is commonly compared to a blueprint. This blueprint orders a highly specific set of corresponding bases‚ which in turn codes for an amino acid. However‚ this specificity comes at a very high risk; a single error in a base could code for a completely different amino acid‚ causing a mutation that could devastate the organism. Recently‚ scientists have discovered a new method to edit and repair DNA that could hopefully complement

strands of DNA double helix are separated‚ each can serve as a template for the replication of a new complementary strand‚ producing two daughter molecules each of which contains two DNA strands with an antiparallel orientation. The enzymes involved in DNA replication process are template-directed polymerases that can synthesize the complementary sequence of each strand with extraordinary fidelity. This complex leads to the local denaturation and unwinding of an adjacent A + T rich region of DNA. The interaction

The Comparison Between China and Japan The reason why I choose the country between China and Japan for my comparison is. China and Japan located in the same continent both of them produce many export goods. But China’s export is mainly in workforce and Japan’s export is mainly their goods that they invented themselves‚ such as Cars and electric. China and Japan is located in Asia. China is the most populous country in the world with number of people crossing 1.298 billion in 2004 and

A Comparison Between Hurricanes and Tornados Throughout history‚ people have been amazed and intrigued by the various forces of nature‚ particularly those associated with weather. In a similar way‚ hurricanes and tornados are some of the most violent natural occurring catastrophes experienced by people. While there are many differences between the two‚ the absolute similarities are tragic. Hurricanes are centered on rough wind swirling around a center area‚ and they are one of the deadliest
