Ihave some questions about biology
the most and accurate answer will get brainliest!

● what does it mean when scientists say that living organisms share a universal genetic code?

● how does a universal genetic code relate to the hypotheses about the origin of life on earth?

● how are self-replicating molecules, such as rna molecules in the “rna world” hypothesis, essential to the most popular hypotheses about the origin of life on earth?

● how might similarities and differences in genetic codes, or the proteins built as a result of these codes, be used to determine how closely related different species are?

Hello there!

Question: #1 ... What does it mean when scientists say that living organisms share a universal genetic code.

When a scientist say that living organisms share a universal genetic code, this would then indicate that the code would signify the code of DNA. We all share the universal code, which had started way back from the first human. Some DNA chimps stay within the family line, and later come back, and that would be the reason to why it would be universal, mainly because everyone has the code, the DNA code.

Question: #2 ... How does a universal genetic code relate to the hypotheses about the origin of life on Earth?

This would relate to the origin of life on Earth based on because the RNA hypothesis that they had taken in 2009. One scholar wrote;, "Based on the genetic code and how it would relate to the hypotheses about the origin of life on Earth would be because of the RNA test that each man from each decade has had". And from this, we can see that from each man, most likely man and women, the hypothesis had been the same, both or either DNA, and RNA affects are the same from the code taken way back.

Question: #3 ... How are self-replicating molecules, such as RNA molecules in the “RNA World” hypothesis, essential to the most popular hypotheses about the origin of life on Earth?

Let's think about this. Self-replicating molecules, such as the RNA, we know that they would reproduce on their own, correct? So, it would be just like the origin of like, just as the plants, plants in water, bugs (some), humans are able to do this, which may require work. But either case, they both SR molecules and the origin of life relate.

Question: #4 ... How might similarities and differences in genetic codes, or the proteins built as a result of these codes, be used to determine how closely related different species are?

As we had considered earlier, the DNA codes maybe change throughout times, and this is normal, but, you are still able to find some similarities still within both RNA, and also the DNA. For example, some proteins would change some substances, and minerals in the body, which would make it really hard to find the resemblance. But, just with one same mineral or something similar, that's when you are able to find the same concept of the body through-out the years of the difference of the RNA and DNA.

I hope it was clear for you, and well understood. Feel free to ask more question on ! :)

okay now i don't know this but for the pints nothing else to say bye
