@@josephxjoestar Hi, im self teaching too and we dont set ourselves exams, we sign up for exams at the end of the year at an exam center, and the exams will be at the same time and date as everyone else doing the A-Level we signed up for e.g. I'm doing my biology a level with AQA and my exam will be at 1pm at 5/06/2024, the same time as everyone else doing their biology a level with AQA.

Hey, thanks for the video, really helpful! Had a quick question though. At about 30:33 you said that the nucleotides are joined together by DNA polymerase to form phosphodiester bonds. However, I thought that the bonds between nucleotides are hydrogen bonds and those between the pentose sugar and the phosphate group in DNA. Could you confirm that?

@MissEstruchBiology Год назад

hello, the bonds between bases on different strands hydrogen bonds, not between nucleotides

Does reducing sugar test only test for disaccharides? I don't understand why acid is added to hydrolyse monsaccharides in the test for non-reducing but no acid is added in the test for reducing.

@MissEstruchBiology Год назад

Reducing sugars tests for all mono and disaccharides, except sucrose. Sucrose is the only one that is non-reducing because the chemical group that is able to reduce is involved in the glycosidic bond. Thats why you have to hydrolyse the molecule, and then it works.
