With binary fission, a parent bacterium divides into two identical daughter cells. Theoretically, can a bacterium be immortal? Since each division gives rise to new cells without the original individual undergoing true aging.

How do the new contractile proteins made in the MPS process get to be part of the muscle cell in myofibrillogenesis (the procsess of structuring new fibers)? do they 1- turn into new sarcomeres (if so, then how do the new sarcomeres get into the existing myofibers)? or 2- fuse with existing ones? or a third option?

Does anyone know what bug makes this sound?? its starts at minute 2:00

As we know biologically humans have consider as animals but through the time of evolution we have changes over the time of period biologically , so what does exactly explanation for this statement?

I am interested in how tetrapods went from early vertebrates, with bones only in their core, to having fully-formed bony limbs, connected to that core.

I can find lots of information about how proto-tetropods went from fins to legs, but these organisms already have bones connecting the trunk to these appendages. How do we get from something with a skeleton like a lamprey, to something with fins that are essentially full limbs?

I'd be particularly interested if you know of a video that shows and explains the full transition from no limbs to terrestrial tetropod feet, (especially if it showed front *and" back legs), but it's that no-limb to bony fin gap I'm most looking to fill, even if just by text.

Thanks in advance!

Edit: I'm looking most for which structures adapted from which, and what incremental advantages may have been provided as those adaptations progressed.

Hello I’m in my 2nd year in college and I love learning about viruses and pathogens . Should I pursue a CLS or a Bio degree ? Also what pre requisite do I need to take ? Thank you .

Hello everybody. I'm a fourth year Btech BT student. As I'm reaching the end of my degree i really cannot decide what exactly to choose. A little guidance would be really helpful. Thankyou.

8 cgpa. I am keen and strong in immunology, microbiology and molecular biology but I find bioinfo a bit tougher. I'm weak in biochem since no matter what I do, I keep forgetting stuff.

I was thinking of doing an mba after graduation but turns out they only take the best of the best into top colleges. I mean I can still do it but it would require a very strong decision of going towards mba which I don't have yet.

About internships, what if I'm underprepared for doing that? Also which kind of internships I could do? Or should I actually pursue mba? Or just go into research?

Please please guide me through this.

I'm curious, I've noticed that when I don't stretch first, I'm able to plank longer

I understand this goes into “eugenics and recognising differences” and is considered taboo, but why are ethnicities not sub species or eco types?
Our genetic similarity means we are all the same species. But our traits like melanin levels, ability to hold breath, bone density, hair colour, eye shape, height are often affected by our needs of different environments.
So why can’t we consider them as differentiating us as much?

Would you want to study the billions of organisms trapped in glaciers for example?

I know about SciHub but this is a really new paper. My university credentials won’t get me in unfortunately:/

Please biology wizards help me.

I have rubber rock climbing shoes that smell terrible. I've tried freezing them and alcohol sprays to help fight the smell but they are borderline unbearable.

I was hoping someone here would know of a cleaning solution I can use to kill the bacteria while not causing too much harm to the rubber.

I understand the very basics of it, such as its molecular scissors (to say) that cuts the DNA in really precise locations among the strand. As far as I understand Cas9 enzyme cuts the gene you are trying to edit with a guide RNA? But I don’t know if I’m understanding correctly, like what do we do with the genes that were cut?

I’m searching for ways to expand my knowledge and learn more about animals in specific and the mysterious universe as a hole

Hey everyone,

I'm trying Native PAGE for the first time to see up until what affinity substrates can be pulled along for the ride on an intact protein. I decided to start off with a commercially available standard protein and standard manual conditions to see how it would behave. After staining the gel I noticed that the gel was empty except for the few millimeters right under the wells, which corresponded with the quantity of protein loaded. Would anyone have some recommendations as to how to improve the migration of protein through the gel? Thank you very much!

Details: Protein is a 60 kDa monomer with a theoretical pI of 6.2-6.3. Samples are diluted in standard pH 7.4 PBS (~10 mM phosphate).
Gel used was a commercial bis-tris 4-20% polyacrylamide gradient PAGE cast at neutral pH compatible with native PAGE as per the product manual.
5x loading buffer is 125 mM Tris at pH 6.8 with 50% glycerol
Running buffer is 50 mM Tris, 50 mM MES, 1 mM EDTA at pH 6.8.

I initially thought that the pI was too close to that of the buffers so I did a second try using pH 8.3 Tris-Glycine buffer as running buffer, which slowed the electrophoresis down significantly but ended in the same result.

Why the cells are programmed to die off? And can we stop that? Or at least slow it down?

Found this video interesting. I hope its ok to post link to YT in here.

Hello guys hopefully I will be in college next year and I was thinking of studying biology. There is a good few courses here that are like that. I was wondering what courses I could do and maybe get a research and development job in a nice pharmaceutical company. The main ones here are: biological and biomedical sciences, biotechnology, biochemistry and molecular biology, neuroscience, microbiology, physiology and immunology. Obviously some of these would be harder to get into than others. Also I suppose that you would have a better chance of getting a job with a masters or even a phd. Anyway guys any answers will be greatly appreciate thanks🔥🔥

Hello,

I'm at a cross road. I'm trying to decide if I want to study plant or human biology. I'm teetering between being able to work with agricultural research or infectious disease research. I really like the idea of getting into gmo research but I also like the idea of getting into vaccine and medical research. Have any of you chosen either path or have any advice?

I have been in college 7 almost 8 years now. My major during this time has changed more than I’d like to admit. I was a biology major starting out since I had wanted to be a veterinarian for as long as I can remember. Chemistry kicked my butt so, I switched to psychology. After almost finishing my degree in psychology, I started working at a vet's office. I loved it so much it convinced me to switch back to biology. After toughing out the first chemistry class with barely a C I was able to get through Chemistry II with barely a C as well. I tried Organic Chemistry I and lost all hope as I've come to find out know my foundation in chemistry is not where it should be. Due to burnout, feeling stupid, and bullying in the workplace I decided to switch completely to fashion design. I wanted to get away from science completely and do something that didn't completely drain me of everything that I was at the time. During this time, however, I have come to realize that my heart is truly drawn to my studies in Biology. In order to fulfill my desire to be a part of biology in some way, I discovered that I could go into Conservation law enforcement, as I have a passion for wildlife and I feel enforcing rules to control populations is important. I’m only three weeks into my classes for this path, however, my professor has confessed something I am completely appalled by. It has made me lose all respect for her, and has completely stripped me of any interest to continue this path. I guess what I’m trying to reach out for is any ideas for new paths I can take while still pursuing my love for the science. I’ve taken two chemistry classes and my local university requires five and I am just not equipped for that. I truly appreciate any ideas. Please be kind, as I feel so lost in this moment.
