Because I only had a digital copy of the exam, not the physical paper. I would've needed the length of the actual image on the paper. But the calculation to do so is (Length of Image / Actual Length of Specimen) x 100.
me ent have so much experience with that but: 1. draw plan diagram neat and good, learn annotations 2. draw graph good 3. learn to write hypothesis 4. learn basic methods for some expts 5. learn basic precautions/limitations for some expts
However, I can say that the phrasing of the question is bad. By saying 'two' nucleotides, it might be inferred to as the opposing nucleotides on the 5' to 3' and the 3' to 5' chains, but H bonds would be correct if they had said the base pairs of those nucleotides not the nucleotides themselves. The question should have said 'successive nucleotides' instead. Phosphodiester bonds are formed by the condensation of the 3' OH group of a sugar on one nucleotide to the 5' phosphate group of the next nucleotide.
good explanation
it help?
@@Strangelove20 yes sir
do you do chemisrty as well?
Bless up sir🙌
cn u do 2022
2022 and 2023 man☹ thanks for this tho
yea, definitely need those
Why didn't you calculate magnification?

sir can you do 2023 P2 U1 and U2 bio
Hi sir any tips on the alternative paper 03/practical part of the EXAM.?
me ent have so much experience with that but:
1. draw plan diagram neat and good, learn annotations
2. draw graph good
3. learn to write hypothesis
4. learn basic methods for some expts
5. learn basic precautions/limitations for some expts
@@Strangelove20 thank you
@@barbiejohnson4l321 If you have specific questions tho, feel free to msg on my ig @kjaredhosein
You change your channel name lol
Anyway wanna thank you i got a 1 in physics last year!
Question 2 part iii
Should be ‘hydrogen bonds’
H bonds hold base pairs together. Phosphodiester bonds hold nucleotides (nitrogenous base, sugar molecule and phosphate group) together.
However, I can say that the phrasing of the question is bad. By saying 'two' nucleotides, it might be inferred to as the opposing nucleotides on the 5' to 3' and the 3' to 5' chains, but H bonds would be correct if they had said the base pairs of those nucleotides not the nucleotides themselves. The question should have said 'successive nucleotides' instead.
Phosphodiester bonds are formed by the condensation of the 3' OH group of a sugar on one nucleotide to the 5' phosphate group of the next nucleotide.
