PPT-DNA, Transcription, and Translation….

Why Should We Learn About DNA To understand how genes are inherited and expressed To understand the evolution of the Earths diversity and protect it To understand the relationships between species. Replication,. Transcription, & Translation. . DNA Replication. DNA Replication. . Before a cell can divide by . mitosis. or . meiosis. , it must first make a copy of its . chromosomes. .. The . DNA. RNA. PROTEIN. RNA and Transcription. RNA. R. ibo. n. ucleic . A. cid. another type of nucleic acid similar to DNA found in cells. also a polymer made of nucleotides. takes information from the nucleus to the rest of the cell. DNA directs the activities of the cell by controlling the proteins the cell produces.. This determines what the cell becomes, what it synthesizes, and how it functions. Gene Protein occurs in 2 steps Transcription and Translation. Objectives. Be able to explain the processes of DNA replication, transcription and translation. https://www.youtube.com/watch?v=gG7uCskUOrA. Replication. DNA makes an exact copy of itself. Unzips. DNA polymerase unzips the DNA by breaking the weak hydrogen bonds that hold nitrogen bases together. Learning Objectives. Learn what a ‘transcription factor’ is.. Learn how oestrogen affects gene transcription.. Learn what siRNA is and how it affects gene expression.. Recap of 15.1. That the cells in our bodies are highly . BNFO 602/691. Biological Sequence Analysis. Mark Reimers, VIPBG. Why TFBS?. Protein transcription factors were among the first gene regulators identified.
