What are the 5 components of DNA?

(The Double Helix) DNA is made up of six smaller molecules — a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).

What are the main features of DNA?

Salient Features of DNA Double-Helix

  • It consists of two polynucleotide chains where the sugar and phosphate group form the backbone and the nitrogenous bases project inside the helix.
  • The two polynucleotide chains have anti-parallel polarity i.e. if one strand has 5′ → 3′ polarity, the other strand has 3′ → 5′ polarity.

What are the 3 main features of DNA?

DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.

What are the four bases of DNA?

There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).

What is the 4 parts of DNA?

The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).

What are the features of DNA replication?

The replication process

  • DNA double helix.
  • Hydrogen bonds break and helix opens.
  • Each strand of DNA acts as a template for synthesis of a new, complementary strand.
  • Replication produces two identical DNA double helices, each with one new and one old strand.

What are the features of DNA double helix?

The salient features of double helix structure of DNA are as follows:

  • There are two polynucleotide chains in a double stranded DNA.
  • The backbone is constituted by sugar phosphate.
  • The two strands possess anti-parallel polarity, means one chain has polarity 5′-3′ and the other has 3′-5′.

What are the 4 proteins in DNA?

Adenine, thymine, cytosine and guanine are the four nucleotides found in DNA.

What are the five basic features of DNA?

The amount of DNA per nucleus is constant in all the somatic cells of a given species.

  • The total amount of DNA in a haploid genome is a characteristic of each organism and is known as C-value.
  • Only a small fraction of DNA is functional in eukaryotes.
  • DNA is the chemical basis of heredity and is organized into genes or cistrons.

    • Answer Wiki. Five basic Features of DNA: 1. It contains two polynucleotide strands wound around each other. 2. The backbone of each consists of altering deoxyribose and phosphate groups.

    What are some characteristics found in your DNA?

    DNA From Parents. Human beings get one complete set of genes from their mother and another from their father.

  • Chromosomes. DNA is coiled up into chromosomes in the nucleus of a cell.
  • DNA Bases. Four chemical bases make up DNA coding: adenine (A),guanine (G),cytosine (C) and thymine (T).
  • Replication. DNA replication is critical to new cells.
  • Uniqueness.

    What are the structural features of DNA?

    Structural Features of DNA | Genetics. 1. DNA exists as a double helix in which the two polynucleotide chains are coiled about one another in a spiral with a diameter of about 20Å (Fig. 1). 2. Concentration of thymine was always equal to the concentration of adenine and the concentration of cytosine was always equal to the concentration of guanine.
