Where is DNA located in a cell? How is DNA replicated? How does the structure of DNA differ from that of RNA? How does DNA replicate? How does DNA unfold itself in space during reproduction? Where is the cell's DNA located? How does the nuclear envelope support the roles of the nucleu...
DNA stands for deoxyribonucleic acid and is our genetic material. Both prokaryotes and eukaryotes have DNA even though prokaryotes lack a nucleus. DNA is passed down from parents to their children. Answer and Explanation:1 DNA lives in the nucleus and directs protein synthesis. Protein...
In order for DNA to be replicated naturally, the two strands that make up its double helix must be separated—how that process occurs has been the subject of much debate. In this new effort, the researchers were able to get the closest look ever at the components involved allowing them to...
Do unreplicated and replicated chromosomes count for the same amount? What is a duplication mutation? How are gene flow and genetic drift similar? What are three differences and one similarity between mitosis and meiosis? How do DNA mutations occur, and in what phase of the replication cycle ar...
Approximately 3,000 restriction enzymes, recognizing over 230 different DNA sequences, have been discovered. They have been found mostly in bacteria, but have also been isolated from viruses, archaea and eukaryotes. It has been estimated that 25% of all bacteria contain at least one restriction ...

Which is more likely: that we are ignorant, blank souls that were created by a capricious god on a whim and need to learn lessons over countless lifetimes in an Earthly classroom, or that we have always been infinite, eternal, soveriegn Spirits that choose to have countless experiences in ...
is that the latter replicate during a defined period of the cell cycle, ensuring a single round of replication per cell. Vibrio cholerae carries two circular chromosomes, Chr1 and Chr2, which are replicated in a well-orchestrated manner with the cell cycle and coordinated in such a way that...

Explain the mechanism by which DNA is replicated. How do DNA and RNA store genetic information? How did RNA and DNA end up together in living things? Describe the steps for DNA processing. How are genes transcribed in eukaryotes? How do cells use the base sequence of a DNA molecule to pr...
