Key Concepts

DNA

DNA, or deoxyribonucleic acid, is the molecular repository of genetic instructions in nearly all living organisms. It contains the blueprint for the development, functioning, and reproduction of cells by encoding information in the sequence of its nucleotide bases.

Hereditary Information

Hereditary information refers to the set of genetic instructions that are passed from one generation to the next. This information determines inherited traits and is stored in DNA, ensuring that genetic characteristics are transmitted during reproduction.

Transcript

00:01 Okay, in order to talk about the transmission of genetic information from one organism to another.

00:08 Okay.

00:09 First, this, imagine this is your cell.

00:13 Okay.

00:15 And this is the nucleus of the cell.

00:17 In that nucleus of the cell, you're going to have a dna that is double stranded, okay? and this dna has a lot of genes.

00:26 And each gene is going to have the information or particularly have the information for all that traits that this organism have.

00:35 So in order to express, for example, let's suppose this is a cell in the eyes, okay, that is going to give the blue eyes color.

00:44 So let's suppose this gene, this is a gene for blue ice color here.

00:50 So it is going to express a mrna, okay? then this mrna is going to move out from the nucleus and bind the ribosomes here in order to produce a protein a protein that is related with the production or with a trait of blue eyes for this organism.

01:12 Okay, this is how it works.

01:14 So, practically, a mrna is just a messenger.

01:17 Okay, this is why it is called messenger rna.

01:20 It is just a messenger.

01:21 There is going to bring the deformation from the gene in dna to the cytosol.

01:26 And why? because dna cannot move out from the nucleus.

01:30 It is very safe here.

01:31 It has to be safe.

01:32 So it remains in the nucleus...
