For example, your standard fixed overhead cost is $3 per unit. If your actual fixed overhead cost is $4 per unit, you have an unfavorable variance of $1. You spent $1 more per unit than you had originally budgeted.
In biology, histones are highly alkaline proteins found in eukaryotic cell nuclei that package and order the DNA into structural units called nucleosomes. They are the chief protein components of chromatin, acting as spools around which DNA winds, and playing a role in gene regulation. Without histones, the unwound DNA in chromosomes would be very long (a length to width ratio of more than 10 million to 1 in human DNA).
What is the function of helicase in DNA replication? A- It joins together Okazaki fragments. B- It untwists the double helix and separates the two DNA strands. C- It adds nucleotides to the new strand in the 5' to 3' direction. D- It checks for errors in the newly synthesized DNA strand. E- It relieves strain from twisting of the double helix as... show more A- It joins together Okazaki fragments. B- It untwists the double helix and separates the two DNA strands.
