Protein Synthesis, DNA Replication

Protein Synthesis, DNA Replication

Protein Synthesis, DNA Replication DNA replication is the process of copying a double-stranded DNA molecule to form two double-stranded molecules.[1][2] The process of DNA replication is a fundamental process used by all living organisms as it is the basis for biological inheritance. As each DNA strand holds the same genetic information, both strands can serve as templates for the reproduction of the opposite strand. The template strand is preserved in its entirety and the new strand is assembled from nucleotides — this process is called “semiconservative replication”. The resulting double-stranded DNA molecules are identical; proofreading and error-checking mechanisms exist to ensure near perfect fidelity.

    Wanda, perhaps a little more education would allow you the knowledge that this exists; as does what is in the Holy Bible. You might be more effective in your pursuit for the TRUTH if you did not come across as functionally illiterate. DNA does give your body INSTRUCTIONS and your ORGANS and your entire make up is as a result of these wonderful DNA. Liberalism may be a mental disorder, but ILLITERACY can be overcome.

    hahahahhahhaahha, next time you have the flu, tell your family md about this one… maybe instead of a vaccination he’ll pray for you, or do some voodoo :)

    Wanda, people like you give religion a bad name.

    By your spelling, it also looks like you have never gone any further than junior high.

    yes actually. with the invention of the electron microscope, DNA, along with many other cellular components, have been seen performing their functions. We have actually seen DNA replicate, be read by transcribed to RNA, and translated in to proteins… the same proteins that are found in every cell in your body.

    DNA is a myth and does not exist, made up by liberal academics to discredit the Bible. Libs also want you to believe the nonsense of evolution and the lies that we are descended from monkeys. Little DNA creatures, shaped as a ladder, giving your body “instrucionts” on how to behave and creating your orgens and bones?!? LOL! How prerposterus! Has anyone ever seen a DNA creature? Who believes this tripe? If you want the TROOTH, read the Holy Bible. Liberalism is a mental disorder.

    This was all DNA replication, what about the protein synthesis?

    this helped a ton…i’ve got a genetics exam later this week on replication, transcription and translation.
