What is DNA

a self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.

200

What is RNA 

ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.

300

What is DNA replication

the process by which the genome's DNA is copied in cells

400

DNA Replication steps 

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.

500

Krebs Cycle definition 

The Krebs cycle summarizes a circular series of reactions in the mitochondria to metabolize AcCoA to two molecules of CO2 with resultant generation of one molecule of GTP, three molecules of NADH, and one molecule of FADH2. GTP is equivalent to ATP in terms of energy charge.

Whats are allele frequencies 

allele frequencies are a reflection of genetic diversity.
