Answer:
GAA TTC GCA Original strand
CTT AAG CGT Complimentary strand
Explanation:
The original strand is already given. It is GAA TTC GCA
Now we need to recognize the complementary strand from the pool of options and pair their bases. Names are written with their letters.
Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines.
- Adenine (A) and guanine (G) derive from purines,
- Thymine (T) and Cytosine (C) derive from Pyrimidines.
In the DNA molecule, Adenine (Purine) forms pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. Two hydrogen bonds join the A-T pair, and three hydrogen bonds join the G-C.
Knowing this, we need to find the correct option, which will pair A with T and C with G.
- 1st Strand → CUU AAG CGU → You can eliminate this option because it includes Uracil, which is a base of RNA. Uracil complements with Adenine, but only in RNA, and now we are looking for a DNA complementary strand.
- 2nd Strand → GAA CCT CAT → None of the triplets pair correctly the original strand. It is not complementary
- 4rth Strand → GAA TTC GCA → This is equal to the original strand. It does not complement it.
- 3rd Strand → CTT AAG CGT → The three triples complement the ones of the original strand. This is the correct option.
G ⇔<em>C</em>
A ⇔ <em>T</em>
A ⇔ <em>T</em>
T ⇔ <em>A</em>
T ⇔ <em>A</em>
C ⇔ <em>G</em>
G ⇔ <em>C</em>
C ⇔ <em>G</em>
A⇔ <em>T</em>
Answer:
The smell of pie from the oven in the kitchen to another room.
A reducing sugar is any sugar that either has an aldehyde group or is
capable of forming one in a reaction thru isomerism. The first example
that should come to mind is glucose, which can form a <span>β(1→4)</span>
linkage. Sucrose, on the otherhand, is a non-reducing sugar. And is
bascially the opposite of a reducing sugar. It doesn't form or have
aldehydes in a basic environmet.Hope this helps!!
Answer:
A) ADH secretion decreases. B) Urine osmolarity decreases.
Explanation:
Antidiuretic Hormone or ADH is responsible for the reabsorption of water through the kidneys.
A) Drinking alcoholic and/or caffeinated beverages decreases the release and effect of ADH so the water does not get absorbed as much as it should, which in turn results in more urination.
B) Osmolarity is a term used to express the concentration of a solution in terms of a certain particle. Since less ADH secretion results in more water being in the urine, this lowers the concentration of the urine. So urine osmolarity would be decreased.
I hope this answer helps.
