What is a GENE ? A Molecular Approach

This video discusses about a Gene at Molecular level.
A gene is a locus (or region) of DNA which is made up of nucleotides and is the molecular unit of heredity. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. Most biological traits are under the influence of polygenes (many different genes) as well as gene–environment interactions. Some genetic traits are instantly visible, such as eye colour or number of limbs, and some are not, such as blood type, risk for specific diseases, or the thousands of basic biochemical processes that comprise life.

Genes can acquire mutations in their sequence, leading to different variants, known as alleles, in the population. These alleles encode slightly different versions of a protein, which cause different phenotype traits. Colloquial usage of the term "having a gene" (e.g., "good genes," "hair colour gene") typically refers to having a different allele of the gene. Genes evolve due to natural selection or survival of the fittest of the alleles.

The concept of a gene continues to be refined as new phenomena are discovered.[3] For example, regulatory regions of a gene can be far removed from its coding regions, and coding regions can be split into several exons. Some viruses store their genome in RNA instead of DNA and some gene products are functional non-coding RNAs. Therefore, a broad, modern working definition of a gene is any discrete locus of heritable, genomic sequence which affect an organism's traits by being expressed as a functional product or by regulation of gene expression.

The diagram that you make from Cell to Gene is 👍👍
It's clears concept..
And even the basic difference between Intron and Exons are just easy to understand...

[preetipaliwal]

Simply u r amazing... What a video yaar... Lots of knowledge in just 5 min... U save our time...

[Furieni]

I have two days to prepare for my biology exam, and you saved my life :)

[suvendu]

This has been the confusing part for me. And now cleared it thank you

[SonuBotany]

Your way of teaching is very unique and easy 🙏

[sanjidahnaznin]

It's amazing..clear conceptual video about gene👍👍

[aiyushsharma]

Nice lecture. Please make a lecture on non coding RNAs and RNAi

[sunkavalliteja]

Your writing is really good. Not a comment it's complement .

[lolowardi]

Thank you very much.
The most interesting explanation for the gene .

[Drbretholz]

So Gene is a portion of DNA which we can not predict which portion it is ... .. Right ... So it is .. ?? what is it? A definition ? Or a portion of DNA, which we not always know which portion, or we can know with calculations? Or computers (from the Genome) ?

[subhasishbanerjee]

I knew much things about genes except what it is actually and it's constituents, you cleared those, thank you

[xcvxcvxcv]

You try to give the video more brightness it will be great if you do

[drashishhomoeopath]

Amino acids ko agar increase Kar deya jaye to gene ko repair kiya jasakta hai Kya sir ???

[kiehore]

Please make videos about SCA disease how is faulty genem
Make proteins

[robertkwiat]

Is the gene technically referring to the coding or noncoding strand?

[misbahhussain]

Sir upload video on mono and polycistronic mrna

[allaboutbiology]

Sir...plz make a video on structure of gene...

[raminkhan]

You are really good at speaking. Thank you it helped me a lot

[justshirley]

Thank you so much!! very helpful. so glad you made this video

If non coding part means intron don't produce protein so why denote it with codon CGA AND TCC bcz they both are protein producing codon or u just use it for understanding and is non coding are unknown or
