WebOct 6, 2014 · Depending on the DNA and ATP concentrations, it took 10–100 s for the motor to package a new DNA molecule. Because the average DNA translocation rate for the T4 packaging machine is about 700 bp/s ( 13 ), the 45-bp DNA used in our assay gets packaged in about 50 ms. WebDNA is packaged into chromatin Although DNA is commonly depicted as linear, chromosomal DNA in the nucleus is actually organized into a higher-order structure called chromatin. This packaging is required to fit DNA with a total length of ~1 m into a nucleus with a diameter of 10 −5 m.

WebDNA and Genomes. DNA (deoxyribonucleic acid) is the genetic material of living organisms. In humans, DNA is found in almost all the cells of the body and provides the instructions they need to grow, function, and respond to their environment. When a cell of the body divides, it will pass on a copy of its DNA to each of its daughter cells. WebDNA Packaging. DNA packaging into viral particles is then initiated by the interaction of a specific viral protein with a particular nucleotide sequence within the genome, the pac site, from which packaging of the DNA then proceeds linearly until the viral coat, called the phage head, is full. ...
