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%.
The statement is false, A cell is to tissue as an organ is to its organ system, not the other way around. as multiple cells make up tissue, organ systems do not make up an organ.
All living things are made up of cells.
