The answer is; DNA helicase
They unzip the double helix into single strands during replication. The unzipping occurs at regions called origins where replication is initiated. The protein breaks the hydrogen bonds (using energy from ATP) between the complimentary bases of the strands hence forming a replication fork.
Answer:
The preferable option will be - B.
B. juxtaglomerular complex.
Explanation:
The cells of the macula densa, the juxtaglomerular cells, and the extraglomerular mesangial cells together form <u>the juxtaglomerular complex or juxtaglomerular apparatus.
</u>
The given options were -
a. nephron loop (loop of Henle).
b. juxtaglomerular complex.
c. renal corpuscle.
d. filtration membrane.
e. afferent arteriole.
- The juxtaglomerular apparatus regulates the blood pressure and also regulates the filtration rate of the glomerulus.
Hyponatremia and decreased urine output are exhibited with syndrome of inappropriate secretion of antidiuretic hormone (siadh).
<h3>What is secretion of antidiuretic hormone (siadh)?</h3>
Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is a condition in which the body produces too much antidiuretic hormone (ADH). This hormone helps the kidneys control the amount of water the body loses through urine. SIADH causes the body to retain excess water. ADH is a substance that is naturally produced in an area of the brain called the hypothalamus. It is then released from the pituitary gland at the base of the brain.
There are many reasons why the body needs to produce large amounts of ADH. Common situations where ADH is (improperly) released into the blood when it shouldn't be produced include:
- During surgery General anesthesia
- Brain disorders such as trauma, infections and stroke
- Brain surgery involving the hypothalamus
- Pulmonary disorders such as tuberculosis, cancer, chronic infections and pneumonia
- Substance abuse
Rare causes include: There is a thing Pituitary
- Leukemia and cancer of the small intestine, pancreas and brain
- Psychiatric disorders

Answer:
The correct answer will be option-C
Explanation:
The CsCl gradient centrifugation in Meselson Stahl experiments is done to separate the bands of the DNA containing isotopes on the basis of difference in the density.
In the experiment, bacterial cultures were grown in the medium of 15N and 14N but if we repeat the experiment with P32 and P31 instead of 15N and 14N and centrifugation is performed then the banding pattern will be the same as of the previous experiment as the method of the replication is same that is semi-conservative.
Thus, Option-C is the correct answer.
In four o'clock flowers, red petals show incomplete dominance over white petals. If two pink flowers are crossed, 50 percent of the flowers will be homozygous, and 25 percent of the flowers will be heterozygous.
