Answer:
The answer is double helix.
Explanation:
In its natural state, each DNA molecule is actually composed of two single strands held together along their length with hydrogen bonds between the bases. Watson and Crick proposed that the DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix.
Hope this helps!! ;)

There are a few theories as to what defines our traits to create our personality
According to one such theory, Dan P. McAdams claims our personalities develop in <span>three </span>stages:
<span>Our genes cause genetic mutations forming a 'draft' personality.During our early upbringing, our parents, teachers and friends treat us differently based on our looks and draft personality.Once we are older we then form a narrative of our lives based on our experiences growing up, and make decisions consistent with the character we have created.</span>
So our traits started from slight genetic variances, which effected how we were treated, which then shapes our own self-narrative. So really, our personality is one big story that we tell ourselves, and our childhood was the prologue to that story.
Answer: <u>Guanine
</u>
According to Chargaff's rule, the base pairing in the DNA and RNA is fixed. Adenine always pairs with Thymine in DNA and Uracil in RNA. Guanine pairs up with cytosine. This complementary base pairing is universal and constant. That's why amounts are also equal. It means if cytosine is 20% in any DNA sample, then amount of guanine would be 20% as well.
