Answer:
Lightly pigmented people tend to be at higher risk of vitamin D deficiency
Explanation:
BACKGROUND KNOWLEDGE:
Human skin is the largest organ of the body which makes boundary line between environment and internal conditions. Human skin cell produces pigment called melanin when ever it is subjected to Sun. More the melanin pigment produced more will be the skin darkens. Ultraviolet (UV) radiations also come from Sun and responsible for more pigmentation.
ANSWER EXPLANATION:
According to the question darkly pigmentation only occurs when their is high level of UV radiations. High level of UV radiations are also responsible for Vitamin D production.
People with lightly pigmented means that there environment has low level of UV radiations which are the requirement of Vitamin D production. Hence due to low UV radiations peoples with light pigmentation's are also be at higher risk of vitamin D deficiency
RNA is a single-stranded molecule, which is made up of similar composition as DNA. RNA differs from DNA in the nitrogenous base as it has uracil in place of thymine.
<h3>What is the complementary RNA sequence?</h3>
- A complementary sequence refers to the copy of the strand or template strand of the RNA. The complementary strand will be the copy of the original strand.
- In the complementary base pairing, guanine will be complementary to cytosine and adenine to uracil.
- In the given sequence of RNA, ACC TAG CGA, the complementary sequence formed will be UGG AUC GCU.
Thus, the complementary sequence will be UGG AUC GCU.
