Receive free material: COMING SOON Find me: Instagram: @professorsamuelcunha Facebook: Biology with Samuel Cunha Summary of the DNA replication (duplication) process: 1 – Separation of the DNA strand by HELICASE. 2 – Forms the REPLICATION FORK. 3 – Each strand is a template for the new DNA chain. 4 – PRIMASE starts the process of making a small piece of RNA, called RNA PRIMER (initiator) – It marks the starting point for the construction of DNA. 5 – DNA POLYMERASE comes into action, binding to the primer. 6 – DNA POLYMERASE adds nucleotides (bases) from 5´ 3´. 7 – One strand is continuous, the other is fragmented. 8 – EXONUCLEASES removes all primers (from both strands). 10 – DNA POLYMERASE fills all gaps in the DNA. 11 – LIGASE connects the fragments. ---- DNA Replication - DNA Duplication - Enzymes - Proteins - Introduction to Biochemistry - Biochemistry Biology with Samuel Cunha - ENEM - College Entrance Exam - Teacher - Samuel Cunha - Biology - Carbohydrates - Lipids - Mineral Salts - Vitamins - Water - Nucleic Acids - Proteins - Amino Acids - Enzymes
