Which term among A-D is not correctly matched with its definition?
A) O Slime layer: loose assemblage of polysaccharide material external to the cell envelope
B) O Polysome or polyribosome formation: multiple ribosomes binding to a messenger RNA transcript
C) O Replisome: two of these complexes working in opposite directions are needed to copy the bacterial chromosome
D) O Nucleoid: cytoplasmic area containing the bacterial chromosome
E) OA-D are all correctly matched
Why does release (the rate of release of minus ends from the nucleation site of the centrosome, allowing the depolymerization of minus ends) cause the decrease of the number and length of microtubules?
The genome of D. melanogaster consists of approximately 1.7 * 108 base pairs. DNA synthesis occurs at a rate of 30 base pairs per second. In the early embryo, the entire genome is replicated in five minutes. How many bidirectional origins of synthesis are required to accomplish this feat?
