A. Wild-type Zif268 binds the sequence 5’-GCGTGGGCG-3’. Rebar is using phage display to generate an altered version of Zif268 that binds the sequence 5’-GCGTGGGAC-3’. He creates a library in which residues Arg 18, Asp 20, Glu 21, and Arg 24 are randomized. Why did he choose these residues? b. if you were generating a Zif268 protein that binds the sequence 5’-GCGGACGCG-3’, what residues would you randomize? Justify your answer.
c. The selected phage from part a have the following sequences:

Position: 18 20 21 24
S Q N R
D A N R
D R N R
D S N R
S S N R
S T N R
T A N R
T P N R
What do the consensus sequences at positions 21 and 24 indicate?
d. Suppose Rebar had created a library in which His 25 and His 29 were randomized. What sequences might you expect to be selected from this library? Why?

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !

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.  

answer; the tunica intima also called tunica interna, consists of elastic fibers,connective tissue and smooth muscle cells;

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
