Answer:
DNA is also called deoxyribonucleic acid which is made up of two chains which wind around each other to form a double helix model. The 2 DNA strands are also called polynucleotides and they are made up of monomeric units known as nucleotides. These nucleotides are made up of one of four nitrogen-containing nucleobases: cytosine, guanine, adenine and thymine, a phosphate group, and sugar known as deoxyribose.
Nitrogen bases present on the two separate polynucleotides strands are bound together with the help of base pairing (such as adenine with Thymine) and with hydrogen bonds to form double-stranded DNA.
So, adenine in DNA is complementary to thymine.

Cells are the basic structural and functional unit of life and possess genes. These genes evolve to carry out new biological functions in the body.
Cells undergo division and growth whether it be unicellular organisms or multi cellular organisms.
All cells possess the property of compartmentalization and metabolism henceforth taking up nutritive material from the environment.
These nutrients are further transformed into the cell compartments and the waste produced as a result is expelled out thus forming on open system.
Grana, thykaloids and storma are components found in the chloroplast within plant cells
Explanation:
we all find ourselves confronted with the age-old question:
what happens when you fall into a black hole?
You might expect to get crushed, or maybe torn to pieces. But the reality is stranger than that.
The instant you entered the black hole, reality would split in two. In one, you would be instantly incinerated, and in the other you would plunge on into the black hole utterly unharmed.
Hope this helps you.. Good Luck
