SOS Response and DNA Repair
HTML-код
- Опубликовано: 7 сен 2024
- The SOS response is a global response to DNA damage in which the cell cycle is arrested and DNA repair and mutagenesis are induced. The system involves the RecA protein.The RecA protein, stimulated by single-stranded DNA, is involved in the inactivation of the LexA thereby inducing the response. It is an error-prone repair system that is attributed to mutagenesis.
SOS genes include lexA, recA, uvrA, uvrB, and uvrD.

Lecture is very precious but pronunciation is not very clear...should not imitate foreign style ...otherwise very good
Thanks buddy....I will stick to real accent.
I am fluent in English language, but I understand every work he says…maybe you are too dumb for this lol🤷🏻♀️
Thank you sir
Thank you sir ❤
great! thank you

@@hussainbiology i hope it will be video about the lab experimnet please.

nice. I have a question. Can you tell me how the cell regulates the preparation of uvrC and uvrD proteins and uvrA protein as they all come under the same promoter?
I have not read any specific regulation for uvrC ,D, and A proteins but i can say the majority of gene expression is controlled via DNA methylation and for these genes to be regulated it must be the CpG islands present on the genes that on/off the expression of any gene by Methylation of CpG islands.

Deep Accent. When one has accent, at least, s/he tries to reduce her/his speed or put subtitle to let others understand what's going on.

Can you please refer a book for this particular topic ?
Great Job :)
Very nice analysis bhai ji

So how does it make SOS repair a direct reversal repair mechanism? Since it is the last resort for the cell to repair extensive damages.
this happens to occur in bacteria as a global response mechanism.
@@hussainbiology Okay so all the direct reversal mechanism occur only in prokaryotes right?
@@anushkasupakar3305 Na na....It occurs in Mammmals too.
Like Photolyases have vast diversity found within bacteria , fungi, plants and in animals too.
Furthermore direct reversals in mammals by MGMT protein
✓ AlKb mediated direct reversal in E.Coli.
@@hussainbiology thank you for the clarification! Thanks a lot. Take care!

It will be nice to hear from you sir if you are from kashmir .

Nothing like that its my exam tomorrow and i am from srinagar brother.

What is sos genes
Any genes which help at the time of urgency
Nice
Thanks for appreciation....Keep supporting

That's not an operon it is a regulon since it's not on the same gene
It is a type of Regulon , which falls under the group of operons........ i hope this makes sense

Apologies........Will stick towards my real accent.
@@mominayasmin6941 I don't even remember I commented this 😂😂
Is it "Translesion " or "translation" DNA synthesis?
at 2:54 It is Translesion synthesis
The Translesion synthesis is a DNA damage tolerance process that allows the DNA replication machinery to replicate past DNA lesions such as thymine dimers or AP sites.It involves switching out regular DNA polymerases for specialized translesion polymerases (i.e. DNA polymerase IV or V, from the Y Polymerase family), often with larger active sites that can facilitate the insertion of bases opposite damaged nucleotides.
