How many nucleotides are needed to code for an amino acid
ivanzaharov [21]

Answer:

Three nucleotide

Explanation:

Three nucleotides are required to code for one amino acid. There are four types of nucleotides A, T, G, C which make DNA. So a doublet of nucleotide code which involves only two nucleotide would be insufficient to code for 20 amino acids because if 4 different nucleotide is taken two at a time then it can only produce 16 amino acid(4²=16).

But if we take three-nucleotide than the number reaches 64 which is more than sufficient to code for 20 different amino acids(4³= 64). Therefore 3 nucleotides are needed to code for an amino acid.

Fill in the blank Competition drives natural selection as individual members of a species compete with each other for limited na
maks197457 [2]

Answer:

1. Intraspecific

2. speciation

3. fossil record

4. The fossil record provides empirical evidence for evolution because it shows that species now aren't the same as species that existed in the past and that small changes happen over time to create new species.

5. A geographic variation in the fossil record occurs when two similar organisms occupy the same time span in two different places. These organisms hold the same purpose within the overall ecology.

6. A more detailed fossil record is preferable for supporting evolution because it allows for the instances of gradual change to be recorded and placed into broader speciation events.

7. Fossils provide a great many intermediaries that connect past species with their living descendants.

8. Intraspecific competition is competition that occurs within species. This is the competition that drives natural selection.
