The human gene for the production of lactose is on chromosome 2. The dna nucleotide sequence of a small part from the middle is 123456789
TACTCGGAA
I haVeTO WRITe DOWN THE EQVIVALENT SEQUENCE FOR MRNA AND HENCE WORK out the sequence of amino acids coded in this part of the polypeptide produced
I get AUGAGCCUU
AUG = METHIONNNE
AGC= SER
CUU= LECINE
is this correct and would you be able to critique this for me
thanks
i have the same oh the Methionine is MET it is a start of the structure
check page 127 as seems your on the ou
To determine the RNA sequence and the corresponding amino acids coded by the given DNA sequence, you need to follow the process of transcription and translation.
1. Transcription:
Transcription is the process where DNA is converted into RNA. During transcription, the DNA sequence is copied to form a complementary RNA sequence. The following base pair conversions occur during transcription:
- Adenine (A) pairs with Uracil (U) in RNA
- Thymine (T) pairs with Adenine (A) in RNA
- Cytosine (C) pairs with Guanine (G) in RNA
- Guanine (G) pairs with Cytosine (C) in RNA
Given the DNA sequence: TACTCGGAA
The complementary RNA sequence would be: AUGAGCCUU
2. Translation:
Translation is the process where the RNA sequence is translated into amino acids to form a polypeptide chain. A codon, which consists of three RNA nucleotides, codes for a specific amino acid. You can refer to a genetic code chart to find the corresponding amino acids for each codon.
Using the RNA sequence AUGAGCCUU, we can determine the corresponding amino acids:
- AUG codes for Methionine (Met) and acts as the start codon.
- AGC codes for Serine (Ser).
- CUU codes for Leucine (Leu).
So the sequence of amino acids coded by the given DNA sequence would be:
Methionine - Serine - Leucine (Met-Ser-Leu)
Your interpretation of the amino acids is correct. However, be cautious of the spelling of the amino acids. Methionine is often abbreviated as Met, not Methionnne. Ensure you use the correct abbreviations for amino acids.
If you have a specific resource or page number to refer to for further clarification, please provide it, and I can review it for you.
