In humans, these traits range from hair color to disease susceptibility. The genetic information encoded by an organism's DNA is called its genome. During cell division, DNA is replicated, and during reproduction is transmitted to offspring.

The offspring's genome is a combination of the genomes of its parents. Lineage studies can be done because mitochondrial DNA only comes from the mother, and the Y chromosome only comes from the father.

In humans, the mother's mitochondrial DNA together with 23 chromosomes from each parent combine to form the genome of a zygote, the fertilized egg.

As a result, with certain exceptions such as red blood cells, most human cells contain 23 pairs of chromosomes, together with mitochondrial DNA inherited from the mother. RNA nucleotides contain ribose rings and uracil unlike deoxyribonucleic acid DNA , which contains deoxyribose and thymine. RNA serves as the template for translation of genes into proteins, transferring amino acids to the ribosome to form proteins, and also translating the transcript into proteins.

RNA contains ribose, rather than the deoxyribose found in DNA there is a hydroxyl group attached to the pentose ring in the 2' position whereas DNA has a hydrogen atom rather than a hydroxyl group. Structural analysis of these RNAs have revealed that they are not, "single-stranded" but rather highly structured. Unlike DNA, this structure is not just limited to long double-stranded helices but rather collections of short helices packed together into structures akin to proteins.

In this fashion, RNAs can achieve chemical catalysis, like enzymes. They also discovered the unidentified fact about base pairing from the work of Erwin Chargaff, which is also called Chargaff rule of base pairing. If you want to receive detailed information about the work of researchers and scientists on the structure of DNA to write your assignment, you can submit your question at assignmenthelp.

RNA is another molecule that was of interest for researchers. All other features are same as that of DNA. Besides these all other structures are almost similar in both these molecules.
