Question: Which two statements are true for the leading strand in DNA?
It is synthesized toward the replication fork.
It is synthesized in the 3′ to 5′ direction.
It is synthesized away from the replication fork.
It is synthesized in the 5′ to 3′ direction.
Answer:
The two statements that are true for the leading strand in DNA are "it is synthesized toward the replication fork and it is synthesized in the 5′ to 3′ direction"
Explanation:
Leading strand in DNA is the strand of new DNA being synthesized in the same direction where the replication fork is moving. The movement of replication fork allows the access of template for the new DNA. The DNA synthesis is continuous in the leading strand. It is synthesized in the 5' to 3' as DNA synthesis always takes place in this direction. This is because dNTP ( deoxyribonucleoside triphosphate) provides free 3' OH group where new dNTP can be added by the enzyme DNA polymerase.
The aerodynamic shape and lightness of the blue shark body allow it
to move “elegantly” across the oceans. It exhibits countershading like
many other sharks. The upper part is an indigo blue tone while the
ventral and the sides are white.
It has a long caudal heterocercal fin. The second dorsal fin measures
almost half the size of the first and its pectoral fins are unusually
long compared to other sharks. Its eyes are large, its teeth are
triangular, and it has a conical snout.
It reaches a length ranging from 3.8 to 4 meters and weighs about 240
kilograms. This species presents slight sexual dimorphism since the
female tends to measure little more than 1 meter in comparison with the
male.

The vitamin that plays an important roles in the epithelia and in the synthesis of visual pigments is vitamin A.
Vitamin A (retinol) is needed for the synthesis of photopigments. The photopigment rhodopsin is synthesized withinside the rods and is answerable for imaginative and prescient beneathneath low ranges of light. When nutritional reassets of diet A are insufficient for a protracted length of time, the quantity of visible pigment withinside the photoreceptors declines.
Vitamin A (VitA) is a micronutrient this is important for preserving imaginative and prescient, selling boom and development, and defensive epithelium and mucus integrity withinside the body.Vitamin A is critical for lots physiological processes, which includes preserving the integrity and feature of all floor tissues (epithelia): for example, the skin, the liner of the respiration tract, the gut, the bladder, the internal ear and the eye.
