Answer:
I think number 1 is the answer.
Stop codons, when read the ribosome stops producing proteins
Answer:
aka Ethenone
Explanation:
Ethenone is an organic compound made out of the elements Carbon, Hydrogen, and Oxygen. It is an example of a covalent molecule. The Hydrogens are single bonded to the carbon and then the carbons and oxygen are double-bonded to each other. Additionally, because there are 2 Hydrogens and 1 Oxygen the ratio is 2:1, as stated in the question.
<h3><u>Answer and explanation;</u></h3>
- This can be done by<u> DNA sequencing which is the process of determining the accurate order of nucleotides within a DNA molecule</u>.
- By doing a DNA sequencing for the two sequences of DNA from the two species it will help compare the number of random mutations which have occurred in a molecular clock in the two species - that is, seeing how different the sequences are.
- This will make it possible to infer how long ago the species diverged.
Species A: GTTGAGCTAGTATGGACC
Species B: GATAAGCTAGTAAGGTCA
These species differ in 5 nucleotides.
This number should be multiplied by the rate of mutations; that is;
5 × 15 million years =75 million years.
