Explain how is dna replicated

This elaborate tutorial provides an in-depth review of the different steps of the biological production of protein starting from the gene up to the process of secretion. Also included are topics on DNA replication during interphase of the cell cycle, DNA mutation and repair mechanisms, gene pool, modification, and diseases Part of the genetic information is devoted to the synthesis of proteins.

Read this tutorial for further details The cell is defined as the fundamental, functional unit of life. Some organisms are comprised of only one cell whereas others have many cells that are organized into tissues, organs, and systems. The scientific study of the cell is called cell biology.

This field deals with the cell structure and function in detail. It covers.. This tutorial looks at the mutation at the gene level and the harm it may bring. DNA Replication. Lawrence C. Brody, Ph.

A pairs with T, and C pairs with G. The color of the rectangle represents the chemical identity of the nitrogenous base. A grey horizontal cylinder is attached to one end of the rectangle in each nucleotide and represents a sugar molecule.

The nucleotides are arranged in two rows and the nitrogenous bases point toward each other. A set of four nucleotides are in both the upper and lower rows. From left to right, the nucleotides in the top row are adenine green , cytosine orange , thymine red , and guanine blue. From left to right, the complementary nucleotides in the bottom row are: thymine red , guanine blue , adenine green , and cytosine orange.

Figure 5: A new DNA strand is synthesized. This strand contains nucleotides that are complementary to those in the template sequence. How long does replication take? More on replication. How does DNA polymerase work? What does the molecular structure of a nucleotide look like? What does the lagging strand look like?
