Why is it necessary for the genetic material in a cell to exist in chromatin form during normal cellular activity, and not in ch
romosome form? a)It requires more surface area in the cell to have the cells condense. b)Condensing into chromosome form requires more energy than the cell has to exert.
c) Chromatin prevents genetic material from being broken off during replication. d)Chromatin form allows the genetic code to be read and proteins to be made.
D- During interphase, when the cell is not dividing, chromatin is less tightly packed compared to our chromosomes, which allows transcription to occur.
d) Chromatin form allows the genetic code to be read and proteins to be made.
Explanation:
Chromatin:
It is the structure of DNA along with histone proteins that are not in condensed form. This structure is further made up of Euchromatin which is loosely packed and Heterochromatin which is tightly packed. Chromatin especially Euchromatin allows the genetic code to be read by polymerase enzymes and proteins to be synthesized.
Chromosome:
It is a highly condensed structure of DNA and histone proteins which is seen during cell division. This structure of heredity material is adopted for the proper segregation of alleles during cell division.
Best choice:
d) Chromatin form allows the genetic code to be read and proteins to be made.
