Adna molecule consists of two polynucleotide strands that form a double helix. the strands are held together by hydrogen bonds between the nitrogen‑containing bases. one strand is complementary to the other strand, which means that a base on one strand is paired with a base on the opposite strand. the nucleotide bases in dna are adenine (a), cytosine (c), guanine (g), and thymine (t). choose the dna sequence complementary to gact (a) agtc (b) gact (c) tcag(d) ctga

D) CTGA

Explanation:

As the question says, DNA consists of two complementary strands held together by hydrogen bonds between bases.

Nucleotides are the monomers of DNA, which means they are the basic building block of it. The nucleotides consists of:

A sugar: deoxyriboseA phosphate. A base: Adenine (A), Thymine (T), Guanine and Cytosine (C)

Adenine pairs with Thymine, they form two hydrogen bonds between them. While Cytosine pairs with Guanine, they form three hydrogen bonds between them. This is because each base can bond with a specific base in a process called complementary base pairing.

So, the complementary sequence of GACT is CTGA.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
