pair up your nucleoide sequence with the mRNA sequence then you will find from the amino acids in the codons what amino acids are present in the lactase production. Each dna sequence coincincids with the appropriate mRNA sequence unless there is a mutation

can someone please show me the mRNA sequence and amino acid codes that is equivalent to the human gene for lactase production ie

position - - 1 2 3 4 5 6 7 8 9 -
nucleoide- - T A C T C G G A A -

MANY THANKS

mRNA Sequence AUG AGC CUU

Amino acid codes: Met, Ser, Leu

good luck with the rest of S103

To determine the mRNA sequence and corresponding amino acids for the given nucleotide sequence, you need to refer to the genetic code chart. The genetic code chart shows the correspondence between nucleotide triplets (codons) and the amino acids they encode.

Here is how you can find the mRNA sequence and amino acid codes for the given nucleotide sequence:

1. Start by transcribing the DNA sequence into mRNA. In DNA, the nucleotide T (thymine) is replaced by U (uracil) in mRNA. So, the given DNA sequence TACTCGGAA becomes the mRNA sequence AUGACCGUU.

2. Once you have the mRNA sequence, divide it into codons. Each codon consists of three nucleotides.

- The first codon is AUG.
- The second codon is AGC.
- The third codon is CUU.

3. Refer to the genetic code chart to find the amino acid codes for each codon.

- AUG codes for the amino acid Methionine (Met).
- AGC codes for the amino acid Serine (Ser).
- CUU codes for the amino acid Leucine (Leu).

So, the mRNA sequence is AUG AGC CUU, and the corresponding amino acid codes are Met, Ser, Leu.

Remember to note that this is assuming there are no mutations or changes in the nucleotide sequence.
