Question

practice: transcribing and translating
transcribe and translate the following dna molecules.

1. dna: taccggatgccagatcaaatc

mrna:
amino acids:

1. dna: tacctgttaagctacaaaatt

mrna:
amino acids:

1. dna: aatacggggcgtaaccacta

mrna:
amino acids:

1. dna: gctagtacgtgcacattagaa

mrna:
amino acids:
(there is a circular chart at the bottom, which is a codon table for translating mrna to amino acids.)

Explanation:

Problem 1:

Step1: Transcribe DNA to mRNA (A→U, T→A, C→G, G→C)

DNA: TACCGGATGCCAGATCAAATC
mRNA: AUGGCCUACGGUCUAGUUUAG

Step2: Translate mRNA to amino acids (using codon wheel)

• AUG: Methionine (Met)
• GCC: Alanine (Ala)
• UAC: Tyrosine (Tyr)
• GGU: Glycine (Gly)
• CUA: Leucine (Leu)
• GUU: Valine (Val)
• UAG: Stop

Step1: Transcribe DNA to mRNA (A→U, T→A, C→G, G→C)

DNA: TACCTGTTAAGCTACAAAATT
mRNA: AUGGACAAUUCGAUGUUUAA

Step2: Translate mRNA to amino acids (using codon wheel)

• AUG: Methionine (Met)
• GAC: Aspartic acid (Asp)
• AAU: Asparagine (Asn)
• UCG: Serine (Ser)
• AUG: Methionine (Met)
• UUU: Phenylalanine (Phe)
• AAA: Lysine (Lys)

Step1: Transcribe DNA to mRNA (A→U, T→A, C→G, G→C)

DNA: AATACGGGGGCGTAACCACTA
mRNA: UUAUGCCCCCGCAUUGGUGAU

Step2: Translate mRNA to amino acids (using codon wheel)

• UUA: Leucine (Leu)
• AUG: Methionine (Met)
• CCC: Proline (Pro)
• CCG: Proline (Pro)
• CAU: Histidine (His)
• UGG: Tryptophan (Trp)
• UGA: Stop

Answer:

mRNA: AUGGCCUACGGUCUAGUUUAG
amino acids: Met, Ala, Tyr, Gly, Leu, Val, Stop
