The processes of DNA replication, gene transcription and protein translation are simpler in prokaryotes compared to eukaryotic cells. Ongoing scientific research is continually uncovering the complexities of these proces... More » Science Biology Molecular Biology & DNA

DNA is found in the nucleus of animal cells. The DNA compounds are packaged into chromosomes inside the nucleus. Each chromosome contains a single molecule of DNA that can be replicated during the processes of transcript... More »

Helicase is the enzyme that is responsible for unzipping the DNA double helix and separating the strands by breaking the hydrogen bonds between them. Helicase is one of multiple enzymes working together in tandem in orde... More » Science Biology Molecular Biology & DNA

DNA replication takes place in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells, HowStuffWorks states. Reference explains that prokaryotes are organisms without a nucleus. More »

The CAAT box refers to a short consensus sequence of nucleotides in DNA that occur close to (about 80 base pairs away) the transcription start site of a gene in eukaryotes. The transcription start site of a gene is where... More » Science Biology Molecular Biology & DNA

The main similarity between transcription and translation is that they are both important phases in the process of protein synthesis. Transcription is the copying of a DNA gene sequence into RNA, while translation is the... More »

The pGLO plasmid is a small circular piece of DNA that contains the gene to produce green fluorescent protein in the model organism. Within the pGLO plasmid, the gene that codes for GFP is typically linked to a gene prom... More »
