Answer:
The correct option is;
A, B, and C, only
Explanation:
The amino group is the functional group of the form CH-NH₂ consisting of single bonds formed between hydrogen atoms, aryl groups, alkyl groups or two or more of such groups combined together bonded with a nitrogen atom. An amine is an organic compound that has an amino group in its composition or structure
Therefore, the amino group can be found in the molecules of A, B, and C only.
Random fertilization allows random combination of genetic information, which helps synthesize genetically unique gametes. The fusion of a unique sperm together with a unique egg can introduce further variation.
TCTCG and AGAGC are the perfect pair.
Option A
<h3><u>Explanation:</u></h3>
DNA is the genetic molecule of a living cell. The DNA stores genetic information of the species inside itself by means of particular pattern or sequence of nitrogen bases called as gene. The gene is comprised of the particular sequence of nitrogenous bases which are four in number - adenine, guanine, thymine and cytosine.
The nitrogen bases are present in both the strands of DNA and they have complementary relationship between them. The adenine forms hydrogen bonds with thymine and guanine pairs with cytosine.
Here the sequence of one strand is given as TCTCG. So according to the complementary pairing process, the opposite strand must have the sequence of AGAGC to maintain the structure.
