How many possible combinations can be made from 6 codons using base pairs?

In summary, the conversation discusses the genetic code and the number of possible ways to get the sequence Leu-Asp-Phe-Ile-Pro-Cys. It is mentioned that there are 6 codons, each made up of 3 base pairs, and that the genetic code is degenerative. The question is how many ways there are to get this specific sequence, and the conversation also discusses the concept of multiplying combinations to find the answer.

This is a math question. really.

So I have 6 codons.
Leu-Asp-Phe-Ile-Pro-Cys.
Now as we've all learned from high school biology, codons are made up of 3 base pairs each.
We've also learned that the genetic code is degenerative, that is, more than one combination of base pairs can mean one single codon.

Leu has 4 different posisble combinations
Asp has 2
Phe has 2
Ile has 3
Pro has 4
and Cys has 2

The question is now, as you've probably guessed, to determine the number of possible ways to get Leu-Asp-Phe-Ile-Pro-Cys.

I'd rather not draw it out. Is there a good equation I could use/way to go about this?

If there are 4 ways to get to City Leu from where you are, and 2 ways from Leu to Asp City, how many ways are there to get to Asp? Think about multiplying the combinations.

Thanks, that helped me visualize the problem!
 

FAQ: How many possible combinations can be made from 6 codons using base pairs?

1. What are "Mathy-genes"?

"Mathy-genes" are a hypothetical concept that refers to genes or genetic traits that are believed to influence mathematical abilities or aptitude.

2. How are "Mathy-genes" identified?

Currently, there is no definitive way to identify "Mathy-genes". Researchers often use genome-wide association studies to look for genetic variants that are associated with mathematical abilities, but the results are still inconclusive.

3. What are condons in relation to genetics?

Condons are sequences of three nucleotides (building blocks of DNA) that code for a specific amino acid. These amino acids then join together to form proteins, which are essential for the functioning of cells and organisms.

4. How do condons affect gene expression?

Condons play a crucial role in determining the sequence of amino acids in a protein, which ultimately determines its function. Changes in the sequence of condons can result in different proteins and potentially alter gene expression.

5. Can variations in condons lead to genetic disorders?

Yes, mutations or changes in condons can lead to genetic disorders. For example, a mutation in a condon that codes for a vital protein can result in a dysfunctional protein, leading to a genetic disorder. However, not all condon variations result in genetic disorders, as some may have no significant impact on protein function.
