Hello guys :smile: Although it is offtopic, but could you please tell me which genetic engineering technology is most suitable for transferring genes from one animal species to another (transgenic animals)? I thought that it was CRISPR/Cas9, but I was told that this technology is mainly used...

Generally, why I am asking this question :oldsmile: The Euclidean geometry is based on four axioms: But all these notions such as point, line, circle, plane are the results of our eyes and our visual cortex, is t correct? None of them exist as such, but they are in our mind only! So, if our...

DaveC426913 I want to know which physiological reasons prevent this :oldsmile:jim mcnamara And it will help to boost a monkey’s (macaques for example) size from current 41-70 cm to let’s say two meters? It would be interesting to see such monkey :oldeyes: I do not imply/plan to receive an...

Hello again :oldsmile: Let’s assume that for some scientific reasons we need to have monozygotic (identical) twins in apes, for example in chimpanzee or bonobo. So I take egg-cell from female, fertilize it with spermatozoon and receive zygote and it (more precisely morula) later can be...

<mentor - Epistemology (how do we know or perceive) is not subject PF supports in the science forums - moved to General Discussion> Since my previous topic The arrangement of our visual system and the objective truth was closed I will open a new one, less philosophical. So, just imagine that...

This is a continuation of my previous topic Is there any linkage between historic Oxygen levels in Earth's atmosphere and organism size? So, let’s forget about primitive organisms and turn our attention to higher ones, for example rodents, primates :oldsmile: Are there any genes discovered...

But it seems to be quite easy and interesting (I mean results) :oldeyes: Perhaps :cool: But if I had free money I would make such experiments regardless it will yield some practical resulst in biology or not, it is just curiosity :oldsmile:

Sound easy to do, why nobody tried to do it? :oldeyes:

But if genetic alterations are not absolutely necessary, then during several years (and hence about 100 generations?) we can probably achieve desired goal? :oldeyes: So, can they in principle grow 30-40 m height? If only “niches” matter, then why nobody tried to receive such giant ferns? It...

Hello :oldsmile: I have heard that various organisms in Carboniferous period had gigantic sizes because of relatively high Oxygen level in atmosphere. Today it is equal to 21 %, but at that time it was higher: https://www.nationalgeographic.com/science/article/carboniferous So, organisms...

Hello people :oldsmile: I would like to discuss one issue here. Let’s imagine that I am looking to the sphere: I can clearly see that it sphere, not cylinder, or cube, or submarine, or dinosaur. So what I see is objective truth. But how do we generally see the objects? We have got two eyes...

BillTre Thanks :oldsmile:

BillTre Well, thanks a lot for a detailed answer :oldsmile: Insertion into genome is better if we want permanent usage of certain gene, but it requires advanced genetic engineering technologies. From the other hand, if we simply inject DNA molecule containing desired gene into nucleus then...

Ygggdrasil Thanks :oldsmile:

atyy BillTre Thanks :oldsmile: Yes, in minor sulci/fissurae if I remember correctly :oldeyes:
