No they are not the same. Gene expression refers to the process by which information from a gene is used to synthesize a functional gene product, such as a protein. It involves two main stages: transcription, where the information in DNA is transcribed into messenger RNA (mRNA), and translation, where the mRNA is translated into a specific protein. Gene regulation, on the other hand, refers to the mechanisms and processes that control the way genes are expressed. Gene regulation can occur at various levels, including transcriptional regulation (controlling when and how often a gene is transcribed into mRNA), post-transcriptional regulation (modifying the mRNA after transcription), translational regulation (controlling the rate of protein synthesis from mRNA), and post-translational regulation (modifying the protein after it is synthesized).
DNA-binding proteins are not typically already present on the DNA strand. Instead, they recognize specific DNA sequences and bind to them through a process known as molecular recognition. DNA-binding proteins have specific domains or motifs that recognize particular DNA sequences through complementary interactions with the DNA base pairs. These domains or motifs may be present in a specific protein or as part of a larger protein complex. Once the DNA-binding protein has located its target DNA sequence, it binds to the DNA strand through a variety of mechanisms, such as electrostatic interactions, hydrogen bonding, and van der Waals interactions. This binding can occur either through the major groove or minor groove of the DNA, depending on the specific DNA-binding protein and the DNA sequence it is binding to. Overall, the binding of DNA-binding proteins to DNA is a complex process that involves molecular recognition and specific interactions between the protein and DNA.
Hello, thank you for this great video. I finally understand this mechanism. Would it be possible for me to use some of you diagrams? If you are willing to share them with a reference to yourself that would be amazing. I have to give a talk at a conference and this would help me a lot.
You are most welcome. These pictures were created using multiple sources such as Powerpoint, Inkscape, etc. You can cite them by mentioning these sources and our channel name th-cam.com/users/biologylectures Hope this helps.
What would happen to the RNA m at the end of translation is it degraded or the translation cycle is repeated with the same mRNA to synthesize the same protein?
Thank you very much for the nice question. . Once mRNAs enter the cytoplasm, they are translated, stored for later translation, or degraded. mRNAs that are initially translated may later be temporarily translationally repressed. All mRNAs are ultimately degraded at a defined rate
Untranslated regions (UTRs) are regions of the messenger RNA (mRNA) that are not translated into protein. However, they play important roles in regulating gene expression and are therefore considered part of the gene. The UTRs are located at the ends of the mRNA molecule, immediately upstream of the start codon and downstream of the stop codon. The UTRs contain various regulatory sequences that interact with specific proteins and RNA molecules to control mRNA stability, localization, and translation efficiency.
I was reading Bioinformatics for Beginners book by Choudhury and coming across this videos has made me understand chapter one more. 🥂
Thanks a lot 😊

Is gene regulation and expression in eukaryotes answer is same...plz reply sir

Lovelyyyyyyyy thanks a lot ❤️
You are most welcome.
very helpful video, thank you!!

Sir is the dna binding proteins aready present on dna strand.if not then how it binds to dna?

Thank you very much Professor
you are most welcome.
Excellent explanation sir
Thanks for liking
Thank you sir
Welcome
THANK YOU!!
You're welcome!
great video man!
Thank you so much. Means a lot 😊
JazakAllah sir .
Plz make more videos of first year MBBs topics
As soon as possible. we will try to upload MBBS topics. Thank you.
Nice video sir 👍 thanks 😊
You are most welcome Deepika
thank you very much professor!!
You are most welcome.
Thankyou❤
You're welcome 😊
Why is the promotor on the 5' end and not the 3' when synthesis is 5' to 3'?
thanks for you
Most welcome

Why are the untranslated regions included under the exons if they are not translated?
Untranslated regions (UTRs) are regions of the messenger RNA (mRNA) that are not translated into protein. However, they play important roles in regulating gene expression and are therefore considered part of the gene.
