What do you think?
In order for you to be confident with your answer, let's try eliminating some choices first. Right off the bat, which choices can you eliminate immediately with your background knowledge?
because dna doesn't contain the info to the cell
That is somewhat correct… a cell contains a nucleus that directs the function of the cell, but a cell nucleus contains DNA.
C is definitely eliminated because CELLS have small organelles… not DNA.
right so out of a or b i pick a because it makes the most sense
Now as for B, you know the saying 'everyone is unique'? Well, same goes for the DNA. No two individuals (except twins) have the same DNA.
Also.. only 23 chromosomes are inherited from each parent. Try researching that up. Keep in mind that I didn't eliminate D yet.
Each of us has a unique set of chemical blueprints affecting how our body looks and functions. These blueprints are contained in our DNA (deoxyribonucleic acid), long, spiral-shaped molecules found inside every cell. DNA carries the codes for genetic information and is made of linked subunits called nucleotides. Each nucleotide contains a phosphate molecule, a sugar molecule (deoxyribose), and one of four so-called "coding" molecules called bases (adenine, guanine, cytosine, or thymidine). The sequence of these four bases determines each genetic code. The segments of DNA that contain the instructions for making specific body proteins are called genes. Scientists believe that human DNA carries about 25,000 protein-coding genes. Each gene may be thought of as a "recipe" you'd find in cookbook. Some are recipes for creating physical features, like brown eyes or curly hair. Others are recipes to tell the body how to produce important chemicals called enzymes (which help control the chemical reactions in the body). Along the segments of our DNA, genes are neatly packaged within structures called chromosomes. Every human cell contains 46 chromosomes, arranged as 23 pairs (called autosomes), with one member of each pair inherited from each parent at the time of conception. After conception, the chromosomes duplicate again and again to pass on the same genetic information to each new cell in the developing child. Twenty-two autosomes are the same in males and females. In addition, females have two X chromosomes and males have one X and one Y chromosome. The X and the Y are known as sex chromosomes. Human chromosomes are large enough to be seen with a high-powered microscope, and the 23 pairs can be identified according to differences in their size, shape, and the way they pick up special laboratory dyes.

oh ok so whats the final answer???? :)
its either a or d right?
Hello, After a long discussion.. the answer would be D... Happy Studying in Openstudy... !!!
D is the rna
