Dna deoxyribonucleic acid essay

Nucleosides differ from nucleotides in that they lack phosphate groups. The phosphate is joined with carbon atom 3 of deoxyribose at one side and with carbon atom 5 of deoxyribose on the other side.

The helix is narrower and more elongated than A form. Adenine will always pair with thymine and guanine with cytosine.

Examples List on Deoxyribonucleic Acid

Thus there is deoxyribose on both sides of phosphate. The pitch is 4. The major groove is wide which is easily accessible to proteins. This is a pentose sugar having five carbon atoms.

The number of base is 10 per turn of helix. The number of bases is Thus, in DNA there are four different types of nitrogenous bases, viz. The base pairing is nearly perpendicular to helix axis. The phosphate molecule is arranged in an alternate manner to deoxyribose molecule.

The sugar phosphate linkage is zigzag.

The sugar phosphate linkage is normal. The base pairs are tilted to helix axis. The purine and pyrimidine bases always pair in a definite fashion.

The helix is narrower and more elongated than A or B form. The four carbon atoms are inside the ring and the fifth one is with CH2 group. The helix is shorter and wider than B form. Hydrogen atoms are attached to carbon atoms one to four.

However, these bonds are weak which help in separation of DNA strands during replication. Main features of pyrimidines are given below:DNA controls every aspect of a person’s body from their eye and hair color, height, and other features. DNA’s specific and unique characteristic can be crucial when solving a crime.
