Sorry for the 1 am post, I can't sleep and this question is stuck in my head sleep hygiene, I know, I know 😅 . I'm trying to track "n" chromosome number and "C" DNA amount for a human diploid cell 2n = 46, DNA content 2C
It's 1 am and I can't sleep so might as well ask this here. I keep going in circles with transcription. Part 1: strands. DNA template strand is 3'-ATGCATGCA-5'. I wrote the mRNA as 5'-UACGUACGU-3' but my guide key says t
I have been going through Werner's postulates for a few days and I can recite them, but I get stuck the moment a question asks me to apply them. The series I am looking at is the classic one in NCERT: CoCl3·6NH3, CoCl3·5

Three subjects, dozens of chapters, and a feeling that there is always more. How do you turn the whole syllabus into pieces you can finish?
Colour-coded my respiratory volumes and capacities page TV in green, IRV in yellow, ERV in pink, RV in grey and I still failed a small numerical. The question gave: tidal volume 500 mL, inspiratory reserve volume 3000 mL
Circuits look scary until you spot the pattern. Here is how to set up Kirchhoff's equations without sign chaos, and when to skip them altogether.
Yaar gas laws pe mera confidence zero hai. Class mein sir ne ek hi equation ke teen versions likha diye aur ab sab mix ho gaya. PV = nRT, \qquad PV = Nk BT, \qquad P = \frac{\rho RT}{M} Mujhe samajh nahi aata kaun sa kab
