In a DNA strand, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C).
Instead of adenine, RNA strands contain uracil (U).
So, the DNA triplet AGT is complemented by the RNA triplet UCA.
Answer:
area = Iw
Explanation:
area = lw
where
l = length
w = width
Therefore,
The area of the shaded region = area of the big rectangle - area of the small rectangle
Therefore,
area of the big rectangle = (x+10)(2x+5) = 2x² + 5x + 20x + 50 = 2x² + 25x + 50
area of the small rectangle = (x+1)(x+1) = x² + x + x + 1 = x² + 2x + 1
area of the shaded region = 2x² + 25x + 50 - ( x² + 2x + 1)
area of the shaded region = 2x² + 25x + 50 - x² - 2x - 1
area of the shaded region = x² - 23x - 49
