Explain the structure and function of tRN/A in protein synthesis. tRNA is only found in animal cells tRNA is made up of lipids tRNA helps in DNA replication tRNA carries amino acids to the ribosome during protein synthesis.Explain the role of RNA polymerase in transcription. RNA polymerase helps in transcribing the DNA into RNA. RNA polymerase breaks down the DNA into smaller fragments. RNA polymerase is not involved in transcription. RNA polymerase helps in replicating the RNA into DNA.Specialized cells that use a lot of energy.such as muscle cells have a lot of Golgi bodies Enuclei D vacuoles D mitochondria A "typo" or mistake when copying DNA is called a(n) D mutation D carcinogen Doopsie D mitochondria What happens in the G1 phase of the cell cycle? D Mitosis D DNA synthesis Cytokinesis D Organelle duplicationWhere does translation take place in the cell? Nucleus Endoplasmic Reticulum Mitochondria RibosomesA cell membrane can be described as being selectively permeable. What does this mean? D It allows certain particles to enter the cell and blocks others. D It allows all types of particles to flow freel in and out of the cell. (1) It allows millions of tiny objects to cross into the cell constantly. It does not allow objects to enter the cell.PREV 145146147148149150151152153 NEXT
