- Genetic engineering is the technique of transferring a gene from one organism to the genome of another. It has many important applications from medicine (eg. making insulin) to agriculture (eg. GM plants to be resistant to pests, diseases and certain conditions). In this video, we will go through the details of the process of genetic engineering.

my friends say mr murray is the better biology youtuber but ive been backing biorach from the day i was created via somatic cell therapy. biorach is the reason i pass my biology a level. i love u
shh
the way you explain concepts so clearly is amazing
Better than the textbook, thank you so much for explaining this
As this topic isn’t on the advanced information my teachers skimmed past it really quickly so I wasn’t too confident but this video and your playlist on manipulating genomes has genuinely helped me so much thank you so much for all the videos you’re a life saver!!!!!
Really glad the video helped! :)
You are an amazing teacher, never stop posting the explanation videos you help us all students. Thank you so much!!! I always recommend you to everyone in my school
Came across your channel last week and it’s honestly the best thing I’ve seen for OCR Biology. I struggle dealing with the sheer content in Biology but your vids make it so much easier to learn and understand. I just wanted to ask how much extra work through the textbook or revision guides should we do after watching your vids ? I’m currently working through the revision guide, whilst watching your videos, along with the occasional look in the textbook if I want something in slightly more detail. Would this, along with doing lots of questions and past papers, be enough to achieve an A in the exam ?
Thank you very much! Your support means a lot to me and I'm very glad to hear how you've found my videos helpful! And also it's great to hear that you're putting hard work into your revision :)
You got the right idea, but I'll put extra emphasis on the importance of exam question practice. Once you've learnt the content of a topic well, then do exam questions AND check the mark scheme. Learn the keywords and phrases that they often look for in exams. Practise writing clear and concise answers, as waffling on is not ideal.
I'd recommend that you check out two websites here:
1. Google "Science retrieval roulette" and you should get to a pink page. Click on the drop-down boxes to find the right course (ie. OCR A-level biology) and pick your topic on the second drop-down box next to it. 5 random questions will then pop up in the big box. Do them, then click on the box to reveal the answers in the back. This will help you check if you know the basic knowledge of the topics.
2. Google "Physics and Maths tutor". The website has got topic-specific exam questions and mark schemes. Just make sure to find the ones for OCR A!
Hope this helps :)
The person that disliked this video deserves to be punished
Is there a vid on gene therapy i think you missed it out on the chapter 21.
This is so detailed and helpful thank you so much , your videos help me slot in understanding the topics
Woop Woop! Thank you for this, much needed! :D
Glad to be of help! Thanks for watching :D
Plz could you do a walkthrough of some of the ocr A Level Biology past papers. Or maybe go through some questions. Thanks
you've made it so straightforward
Your videos are better at explaining than my teachers at school.
Can you please make a video about the heart and cardiac cycle. the TISsue like SAN and AVN
Haha thank you for your kind words :) it's on my list already!
Does the reverse transcriptase method still have sticky ends? Thanks
You are an angel :)
do u have a video on 'effects of nervous mechanisms on heart rate' (module 5)?
No not quite, but I'll put it on my list of topics to cover :) thanks for the suggestion!
Can you please do a video on measuring the process of ventilation?
I'll add it onto my list of topics to cover :) thanks for the suggestion and for watching!
Can I watch these even tho I’m doing edexcel?
Of course! The major difference between exam boards is the style of exam questions and mark schemes, but otherwise the science is the same :) I'd suggest that you watch the video, then check with your textbook and see if there are any details that may be slightly different, just to make sure you won't miss anything out!
is the whole unit here?
I love u
