If a cell is just a collection of enzymes causing chemical reactions that make the cell do what it does, then how can a set of chemical reactions create the enzymes it needs, and how can the cell reproduce? Where does the miracle of life come from? The answer to these questions lies i...
Do all cells reproduce the same way? Why/How does DNA decide everything? What enzymes are involved in replication?DNA:DNA stands for deoxyribonucleic acid. DNA is our genetic material that we inherit from our parents and that we pass on to our ...
Biology - How do Organisms Reproduce?Previous Quiz Next IntroductionA basic occurrence in reproduction is the creation of a DNA copy; to produce copies of the DNA, cells use chemical reactions. The DNA in the cell nucleus is actually the information source for creating proteins. Likewise, if ...
cells dividing out of control What do cells normally have to keep cell division under control checkpoints During G1 there are checkpoints for what damaged DNA what does p53 protein promote during G1 p53 protein promotes genes involved with DNA repair to be expressed if the DNA is damaged ...
coli to sense food, move around, eat and reproduce. So, in any living cell, DNA helps to create enyzmes, and enzymes create the chemical reactions that are "life." Bacteria reproduce asexually. This means that, when a bacteria cell splits, both halves of the split are identical -- ...
How is PCR used in DNA sequencing? How are enzymes involved in DNA replication? How do single-stranded DNA viruses replicate? How does Z-DNA form? How does a DNA virus reproduce its host genome? How does Sanger DNA sequencing work?
Bacteria are single-celled microbes, and are one of the simplest forms of life on earth. Containing just a single chromosome of DNA, they lack a nucleus or other organelles found in most eukaryotic cells. To replicate, bacteria undergo the process of bin
double its normal size. Next, it makes a copy of all of its genetic material. This is through a process called DNA replication. Last, the cell actually splits down the middle into two identical ‘daughter’ cells.This process is roughly the same as how our body cells reproduce. ...
Bacteria, however, lack a nucleus, and theirDNAfloats freely within the cell. These microscopic cells don't have organelles and possess different methods to reproduce and swap genetic material. Bacteria are classified asprokaryoticcells. Basic categories aside, scientists also place bacteria in differen...
“For the transport of tau aggregates from cell to cell, we see two pathways in particular. Transfer between cells that are in direct contact, and transport within vesicles that act as cargo capsules, so to speak, and pass from one cell to another to eventually merge with it,” Vorberg ...
