Genetics 1
Where does the diversity among organisms come from?
The nucleus of their cells stores different genetic information, which is found within structures called chromosomes that are formed by DNA.
Why do you resemble your parents?
Because the DNA information is transferred to descendants.
What are the three parts that compose a nucleotide?
A phosphate group, a pentose (sugar) and nitrogenous base.
What is a genome?
A genome is the complete set of genetic information in an organism.
How is called the basic unit that contains the genetic information for a particular trait or character?
A gene.
What are the four possible nitrogenous bases that compose DNA?
Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).
How many hidrogen bonds there are between A and T?
Two hidrogen bonds.
How many hidrogen bonds there are between G and C?
Three hidrogen bonds.
What is the scientific field that analyzes and interprets all the complex genomic data?
Bioinformatics.
What is comparative genomics about?
Comparative genomics consists in comparing the genome of organisms in order to grasp the differences in their genomic features (e.g. genes).
