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:
In about 30 days
Explanation:
Assume Xavier sights a full moon today, it'll take around 29.5 days to see the moon at that size again.
Analysing each of the given options, only option D answers the question because 29.5 days can be rightly said to be about 30 days.
Or better still, 29.5 days approximates to 30 days.
The answer is 5.1 because the nucleus will work faster
The plant responds to severe heat stress by producing heat-shock proteins, which may protect the plant's proteins from denaturing. These heat-shock proteins or chaperones are responsible for protein folding, assembly, degradation and also translocation in many cellular processes. Additionally, they stabilize proteins and membranes and can also assist in refolding of proteins under stress conditions.
