In apoptosis, a process of programmed cell death, the cell undergoes controlled degradation of cellular components including nuclear DNA Researchers have noted that if the DNA is isolated from an apoptotic cell, it appears as distinct bands of multiples of approximately 145 bases in length. Why does this occur? Multiple Choice There is a specific DNase that digests DNA every 145 base pairs. ODNA sequences that appear every 145 base pairs allows for easier DNA breakage. DNA that is wrapped around the histones is not being degraded. DNA is coated with transcription factors every 145 base pairs.

Genome annotation

The technique of linking biological information to genome sequences is termed genome annotation. Gene annotation is the method of identifying gene locations and coding sections. It helps us understand what these genes are doing in the body through establishing structural characteristics and linking them to the actions of various proteins.
