Cells are like fine tuned machines. They work to maintain a balance by removing what is not needed and obtaining what is. For example, if a particular enzyme such as helicase is needed, the nucleotide sequence related to that protein will be exposed and the protein made. The nucleotide bases below are an example of a segment that would be used to produce a protein. Which protein chain will be formed from this nucleotide segment? NOTE: A codon chart is provided below.

TACAAACGGTTGACT


Answer Choices:
Met - Phe - Ala - Asn

AUGUUUGCCAACUGA

Cys - Leu - Pro - Thr-

Asn - Ala - Phe - Met

Respuesta :

Iqta

Answer:

The answer is Met - Phe - Ala - Asn

Explanation:

DNA Sequence:

TACAAACGGTTGACT

mRNA Sequence:

AUGUUUGCCAACUGA

Genetic Code:

  • The genetic code defines the base sequences on the mRNA and their corresponding amino acids.
  • The code comprises of 64 codons that code for 20 amino acids.
  • According to the genetic code, the codon AUG is known as the start codon. This codes for methionine and is the starting point for translation of mRNA sequence into protein.
  • UUU codes for the amino acid phenylalanine.
  • GCC codes for the amino acid alanine.
  • AAC codes for asparagine.
  • UGA is a stop codon and it terminates translation.
