1. Questions for 1.05 Early Atmosphere Assignments.
1. What does it mean when scientists say that living
organisms share a universal genetic code? The scientist
means that all living organisms share a genetic code which
all living organisms have a genetic code. Like Humans,
animals , and other species have genetic codes and DNA
2. How does a universal genetic code relate to the
hypotheses about the origin of life on Earth?
The Universal genetic code relates to the hypotheses
because it shares the formed life of earth. Like one true cell
can pass genetic information to one microsphere to
another microsphere.
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?
Like the RNA cells would pass on their genetic information and
then it would help them explain why the species have the same
or share the genetic codes. Reproduction.

2. 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?
It depends on the species DNA compared to another species to
determine if the species are related or not. Like the human and
the rhesus monkey they are closely related because all the
genetic codes have the same DNA except one.
5. Based on the amino acid sequence data, what species do
humans appear to be most closely related to and most
distantly related to? Explain your answer
I would say the Human and the Rhesus Monkey because they
both have the same genetics but they only have different
genetic code at least one genetic code that is different from
the others. The donkey and the horses are distantly related.
