a fact.

Flowers tend to respond to stimuli

There are many different kinds of stimuli for which is different for every organism, for example, water, light and carbon dioxide are three stimuli and materials needed for photosynthesis in plants to manifest.
<span>In humans, we have nutrients or food, oxygen and water for us to survive. These are stimuli, eyes need light as a stimuli for it see and function. Nasal receptors needs smell as stimuli caused by molecular reactions of an object as a stimuli. And others.<span>

Why does DNA need to be copied into mRNA?
larisa86 [58]

mRNA will serve as reference book that contains information as the DNA and its sequence is complementary to the DNA template.

The transfer of information in a DNA strand to a new molecule of messenger RNA is known as transcription. Thus, the process of transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors. However, DNA is copied into mRNA because mRNA will serve as reference book that contains information as the DNA and its sequence is complementary to the DNA template.

valentinak56 [21]

Answer:GGATCGA

Explanation:

The complementary double helix of the DNA are antipararell to each other.

Chargaff's rule state that Adenine always pairs with thymine (double bond) and Cytosine always pairs with guanine (triple bond).

Therefore if a DNA molecule is CCTAGCT, then the sequence on the complementary strand of DNA will be GGATCGA as written below

5' CCTAGCT 3'

3' GGATCGA 5'
