Some restriction enzyme recognition sites are not necessarily rotationally symmetrical. For example, the enzyme Btg I cleaves DNA at the site 5' C^CRYGG, where the symbol ^ represents the cleavage site, R= either purine, and Y = either pyrimidine. Make the simplifying assumptions that equal amounts of each of the four bases exist in the human genome and that the base sequence is random. How frequently would you expect to find Btg I sites in the human genome? How many of these sites would you expect to have rotational symmetry? a. Once in 1024 base pairs; none of them.
b. Once in 4096 base pairs; none of them.
c. Once in 4096 base pairs; half of them.
d. Once in 1024 base pairs; one fourth of them
e. Once in 1024 base pairs: half of them
f. Once in 4096 base pairs; one fourth of them.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.  

c is the correct answer hope this !

yes

no

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.
