Answer:
G - 21%
T - 29%
A - 29%
Explanation:
Nucleotide bases in DNA are complementary. Adenosine (A) binds to Thymine (T) while Cytosine (C) binds to Guanine (G). Hence the composition of A in DNA is the same as that of T; and that of C is the same as that of G.
From the information given, C is 21%
Therefore G is also 21% of the genome as C is bound to G, the therefore are the same proportion.
C and G make up 42% of the genome (that 21% + 21%).
The remaining 58% (100%-42%) is made up of A + T
Similarly the proportion of A is equal to that of T,
Hence A is 29% (half of 58%) and T is 29%.
Silicate minerals are the most common of Earth's minerals and include quartz,feldspar, mica, amphibole, pyroxene, and olivine. Silica tetrahedra, made up ofsilicon<span> and oxygen, form chains, sheets, and frameworks, and bond with other cations to form silicate minerals.</span>
