Answer:
If a DNA strand has the base sequence TTCCGGAA the complementary strand has the sequence AAGGCCTT.
Explanation:
A DNA molecule is constructed from sequences of its four nitrogenous bases: adenine, thymine, guanine and cytosine. Since DNA is made up of two strands, the sequence of nitrogenous bases of one strand is complementary to the other
.
The complementarity of the bases is a characteristic of the nitrogenous bases in the nucleic acids to combine with their complementary base, which is the same as saying that purines complement with pyramidines.
- <em>Adenine is combined with Thymine A=T
</em>
- <em>Cytosine is complemented with Guanina C≡G
</em>
In this way, given a sequence on a DNA strand
:
<em> T-T-C-C-G-G-A-A</em>
The complementary strand will have this sequence:
<em> A-A-G-G-C-C-T-T</em>
Answer: Option C. consists of ancestor species and all of its descendants groups.
Explanation:
Monophyletic clade refers to a group composed of a collection of organisms, including the most recent common ancestor of all those organisms and all the descendants of that most recent common ancestor.
A monophyletic clade is also called a taxon. By classifying organisms based on their biological diversity and evolutionary history, we can easily know, how different organisms, both past and present, are related to one another. Examples of monophyletic groups include: Mammals, birds, angiosperms, and insects.
The tonsils located at the base of the tongue are the lingual tonsils.
