    Nucleic Acids, DNA replication and protein synthesis.

    4 star(s)

    DNA stores genetic information, and RNA allows that information to be made use of in the cell. NUCLEOSIDES Both DNA and RNA contain nucleotides with similar components. In RNA the sugar components is ribose and deoxyribose in DNA. The prefix 'deoxy' means that an oxygen atom is missing from one of the ribose carbon atom. When a sugar bonds together with a nitrogen base, it creates a structure known as a nucleoside. There are five nitrogen bases found in RNA and DNA. These bases are divided into two categories based on their molecular structure 1. Purines (adenine & guanine) 2.

    Evolution vs. Intelligent Design

    and their harshest criticism. He addressed the concept of natural selection, in which life evolves through random mutations. Many concepts within evolutionary theory have been corroborated by scientific evidence. Scientists have been following DNA's footprints, which have been permanently engraved by concrete genetic research. Therefore, usually don't refute the basic tenets of evolution. There are some scientists and non-academics that do attempt to debunk the theory of evolution by purporting the notion of intelligent design (abbreviation: I.D.). Proponents of this spiritual concept look beyond the material world and assume that divine intervention has rendered the creation of life on earth.

    Nucleic acid, DNA replication and Protein Synthesis

    3 star(s)

    Adenine always pairs with thymine, and guanine always pairs cytosine. The bases are held together by hydrogen bonds. Watson and Crick's model also suggested a way in which DNA could make copies of itself. First, the ladder untwists. Then the bases break apart. Since and adenine nucleotide can only bond with thymine, and guanine can only bond with cytosine, new units are assembled in precisely the same order as old. When the splitting and pairing processes are competed, two identical DNA molecules stand in the place of one. The process by which DNA makes copies of itself is called replication.

"DNA is just another operating system waiting to be hacked."

-Marc Goodman

Just 60 years ago, Watson and Crick described the structure of DNA for the first time. Now, we have a map of the entire human genome, and we're making new discoveries every day. If you've been following the news about genetic markers for cancer and Alzheimer's, or the controversies surrounding stem cells and GMOs, then you've probably noticed that genetic research is rapidly changing the world. If this excites you, and you thrive on hard work and critical thinking, then studying genetics at university level might be a good fit for you.

The degree will entail plenty of lab work, and where there's lab work there are lab reports. If your writing needs a bit of support, come learn to edit your own work with Marked by Teachers' collection of biological science papers. Make the teacher-marked essays a regular study tool, and before long your writing will excel anything you've done before.

Specialising in genetics at the undergraduate level can be a starting point for careers in industry and medicine and for research in fields like genomics and conservation.
