Which Statement About Lampbrush Chromosomes is incorrect

Question

Which statement about lampbrush chromosomes is incorrect? A)More DNA is looped out from the axis than is required for a single gene. B)They are meiotic chromosomes. C)Looped out regions are active in RNA synthesis. D)The loops consist of two DNA helices,whereas the axis consists of a single DNA helix. E)Instead of being condensed,they are extended.

Accepted Answer

Lampbrush chromosomes feature loops that are extended regions of chromatin, which are actively involved in RNA synthesis. These loops are not simply two DNA helices; they are more complex structures involving DNA and proteins, and the axis of the chromosome is also not limited to a single DNA helix but is a complex structure. Thus, the statement about the loops consisting of two DNA helices and the axis consisting of a single DNA helix is incorrect.
