What Does DNA Do? DNA is like a set of instructions that govern the arrangement of amino acids. It is composed of various 3 letter codes, calledcodons. These codons need to be interpreted in order to attain the correct amino acid. Think of it as a password that, if entered correctly, ...
Cells can vary between 1 micrometer (μm) and hundreds of micrometers in diameter. Within a cell, a DNA double helix is approximately 10 nanometers (nm) wide, whereas the cellular organelle called a nucleus that encloses this DNA can be approximately 1000 times bigger (about 10 μm). Se...
RNA transcription is associated with a transcription bubble, which consists of an unwound template DNA that is accessible to RNA polymerases and transcription factors.The short answer to your second question is no, transcription generally does not happen at the same time as DNA replication. In ...
Prior to sequencing, the DNA library must be attached to a solid surface and clonally amplified to increase the signal that can be detected from each target during sequencing. During this process, each unique DNA molecule in the library...
What does it do? DNA Replication: DNA replication is an important process that occurs as the cell is beginning to divide into two. This is because the new daughter cell will need its own DNA, and so the original DNA needs to replicate. ...
DNA polymerase is an enzyme responsible for synthesizing new strands of DNA during DNA replication. It adds nucleotides to the growing DNA strand, using a DNA template and a primer as a starting point. DNA polymerase specifically catalyzes the formation of phosphodiester bonds between the added nucl...
DNA is shared by two species is to compare their complete DNA sequences (or genomes) with each other. However, determining the entire DNA sequence of an animal is a difficult task that takes significant time and effort. It requires a great deal of equipment, resources, and funding to do ...
