@@lifeasmbali9606at 11.47 the answer for 2.1.4 (b) is CCU since you change it from GGA (only change it once since you going from mRNA to tRNA). Hope that this makes sense and that it’s clear?
Sir question 2.1.4 is more complicated 🙏🙏 There are so many changes that cause confusion even though i have a little bit understanding About Effect on protein formed
Try to remember the order in which the changes occur: if DNA base triplet changes, then mRNA codon changes, tRNA anti-codon changes, which then changes the amino acid, and results in a different protein being formed.
@@MrParkerGr11-12 I understand that basic sir but am confused. The DNA nitrogenous sequence coded for mRNA Changed the first T By G And C by A, That leads to CUA mRNA and UCC. Why do we not using the changed DNA nitrogenous sequence for the change of anticodon Because I saw you sir using TAT changed to UAU My confusion is here actually 🙏🙏🙏
@@MpilonhleMpanza-t5mit would not be incorrect to mention the changed DNA sequence in your explanation. The reason why the focus is on the mRNA codon changes is due the fact that the mRNA codon is needed for the tRNA anticodon. That is why the changed mRNA codons are mentioned in the explanation
Thank you sir❤
It's a pleasure
isn’t 2.1.2 supposed to be AGT? 6:22
as well as 2.1.3 b) isn’t it supposed to be CAT? or are we supposed to change it twice? from trna to mrna to dna? 11:47
For 2.1.2 the answer is TCA since the nitrogenous based given is found on tRNA. So yes, it must be changed twice to get the DNA base triplet

@@MrParkerGr11-12i was talking about 2.1.3 b) but i see that you have to change it twice. thank you
Plz explain 2.1.4 (b).........I don't seem to understand

I thank very much sir
Everything is clear I got this
I hope I will write fantastic on the next day
@@MpilonhleMpanza-t5m It’s a pleasure. I wish you all the best for your last Life Sciences exam 💯
