<p>when I was solving some of the Test Of Biology E/M I was faced questions and I hope that I find her answer with you</p>
<p>(Real SAT Book)</p>
<p>the sequence for acertain protein has been isolated and sequnced from five diffrent species . during their evolution from acommon ancestor , these species have undergone only single nucleotide mutation .a partial DNA sequence from each of the five species is :
I.3'....AGTAC...5'
II.3'...AGTTC..5'
III. 3'..AGTAT..5'
IV. 3...TGTTC..5'
V. 3' ACTTC..5'</p>
<ol>
<li>which of the species would require fewest point mutaion in the original sequence in order to give rise to the new sequence 3'GGTAT5' ?</li>
</ol>
<p>A) I
B)II
C) III
D) IV
E) V</p>
<p>2.which is most likely to be the oldest species if 3'AGAAC 5' were the partial DNA sequence of the chromosome ancestor of the group ?
A) I
B) II
C) III
D) IV
E) V</p>
<ol>
<li>the more frequent occurrence of pattern Bladness in men than in woman ?
A. Linked genes
B. Sex influenced trait
C. Autosomal reccessive
D. sex linked trait
E.leathal allel<br></li>
</ol>
<p>4.Two mature plants that are each 12 centimetres in Hight are croosed and produced offspring ranging from 4 to 18 centemetre in height when mature of the follwing .which is most likely explanation of these result ??</p>
<p>A)Tallness is Dominatnt Over Shortness
B)Multiple genes affect Hight in palnts
C) Height is sex linked Trait in plants
D) Nondisjunction has occured
E) a Mution has occurd</p>
