hesis RNA Synthesis: Transcription Transcription is the process where a segment of DNA is copied into RNA by the enzyme RNA polymerase. This process involves: Unwinding the DNA double helix at the gene of interest Assembling complem
ocesses; it also involves appreciating their roles in health, disease, and biotechnology: Genetic mutations: How changes in DNA affect protein function Gene expression regulation: Turning genes on or off Biotec
copy of the genetic material during cell division. It is a semi-conservative process, meaning each new DNA molecule consists of one original and one newly synthesized strand. Steps of DNA Replication Initiation: The replication fork forms at origins of
nt, and reproduction of organisms. How does the structure of RNA differ from DNA? RNA is typically single-stranded, has a ribose sugar, and contains uracil instead of thymine, unlike DNA which is double-stranded with deoxyribose and thymine. What role does mRNA play in protein synthe
