Question

Compare the structure and function of dna and rna nucleic acids

Answer 1

Answer
_______

The image of the DNA double helix is the best place to start when you compare and contrast DNA and RNA. This double-stranded molecule contains the four bases adenine, guanine, cytosine and thymine, plus a backbone formed from the sugar deoxyribose and phosphate. RNA, on the other hand, is single stranded and uses the sugar ribose in its backbone, which contains one more oxygen atom than deoxyribose. When it comes to chemical bases, RNA substitutes the base uracil for thymine.

Answer 2

Answer:

DNA is deoxyribonucleic Acid and RNA Ribonucleic Acid

Explanation:

• DNA is made up of Adenine (A), guanine (G), cytosine(C) and Thymine (T).
• The base pairs of DNA is made up of A, G, C and T .
• Each base pair is attached to a sugar molecule and a phosphate Molecule. This unit ( base, sugar and phosphate) is called Nucleotide.
• This Nucleotide arranged in the double helical structure or spiral structure called Double Helix.
• sugar and phosphate are in vertical position.

Function:

Its main function are:

• DNA can make copies of itself.
• It is the genetic material in most of the living beings.
• It controls the metabolic activities by protein synthesis. So it is called as the Masté molecule

RNA:

• RNA is nucleic acid which has the similar structure like DNA.
• But it is of single stranded.
• The backbone of the RNA is made up of alternate phosphate group, the sugar ribose.
• Four bases are attached to this. These are Adenine, Cytosine, Uracil and Guanine.

Function:

Its main ne function are

• To construct Cells.
• Create Proteins
• Carries genetic information
• Carries Amino acid from one part to the other part of the body .
