What is the nucleotide sequence of the mRNA Strand?
The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain. The anticodon is the complementary three nucleotide sequence in the appropriate tRNA. b. Template strand is the DNA strand off which the mRNA is synthesized.
What is the 3 nucleotide sequence on mRNA?
anticodon – a sequence of three nucleotides on a tRNA molecule that bond to a complementary sequence on an mRNA molecule. The anticodon sequence determines the amino acid that the tRNA carries.
What are the nucleotides of mRNA?
It was also known that there are only four nucleotides in mRNA: adenine (A), uracil (U), guanine (G), and cytosine (C).
How do you turn a DNA sequence into mRNA?
During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1).
How do you find the sequence of an Anticodon?
Each tRNA has a set of three bases on it known as an anti-codon. The anti-codon matches complementary bases in the mRNA sequence. To determine the overall anti-codon sequence that will match a strand of mRNA, simply retranscribe the RNA sequence; in other words, write out the complementary bases.
What are the sequence of these stop codons?
There are 3 STOP codons in the genetic code – UAG, UAA, and UGA. These codons signal the end of the polypeptide chain during translation.
What are the three parts of a nucleotide?
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
