Question

in DNA molecule, guanine binds with Regarding the four bases in DNA, the double-stranded DNA molecule is held together by complementary bases. In the DNA molecule, a. guanine binds with ______ b. and adenine binds with ______ in DNA: inRNA, adenine binds c. with ucacil instead. d. Therefore, if the codon on the DNA strand is CAG, then the mRNA codon that will bind to it will be _____. e. Go to the chart, figure 2.1, in your text. (THE CHART IN THE TEXT IS FOR THE DNA CODONS). For the DNA codon GAT, the amino acid that would result would be ______. The following questions relate to chs. 3 and 4: 3 The four evolutionary forces are: Mutation, gene flow, 4. Read the following description and answer the questions (a and b) below.

Explanation / Answer

(a) ln DNA, Guanine(G) binds with cytosin(C)

(b) Adenine(A) binds with thymine(T).

(c) ln RNA, adenine binds with uracil(U).

(d) Therefore, if codon on DNA strand is CAG, then mRNA codon that willl bind to it will be CAG.

(e) for the DNA codon GAT, the amino acid that would result would be Asp (aspartic acid).
