(1)
To determine: The first start codon in the given DNA (deoxyribonucleic acid) strand.
Introduction: There are two type of nucleic acid: DNA and RNA. Both the
(2)
To determine: The sequence of complementary mRNA (messenger ribonucleic acid) bases following the start codon.
Introduction: RNA is essential
(3)
To determine: The amino acids translated by the given mRNA triplets.
Introduction: Amino acids are the building blocks of proteins. There are 22 standard amino acids that are involved in formation of proteins. these amino acids are encoded by specific mRNA codons.

- Identify the features of tRNA that are important in decoding genetic information and converting it into protein language.arrow_forwardThe peptide hormone oxytocin induces labor by stimulating the concentration of uterine smooth muscle. Its amino acid sequence is as follows: Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly.Write a messenger RNA sequence for that sequence. Write the sequence of the two strands of DNA nucleotides that carry the information. for that protein.arrow_forwardAssume the first nucleotide in the sequence is at the +1 position. Transcribe the DNA sequence into mRNA and then translate it into the polypeptide. Give the polypeptide sequence in the following form: Met-Thr-Trp-Tyr-Val etc. 5' ACCGAAGGACTTATGGAGCGCTCATGATTTGCT 3'arrow_forward
- A strand of DNA contains this nucleotide sequence: TACTGCCTCCCCATAAGAATT. The corresponding nucleotide sequence of the mRNA strand from this DNA template is as follows: AUGACGGAGGGGUAUUCUUAA. Q: What is the amino acid sequence of the polypeptide that is produced form the mRNA strand? As well, draw a labelled diagram of the mRNA molecule being transcribed from this strand of DNA.arrow_forwarda) Identify three types of RNA and provide a description of each and the role they play in protein synthesis.

Use your Amino Acids Reference Sheet to complete the following table. Fill in the blank spaces of each row with either the missing DNA triplet, the mRNA codon, or the Amino Acid. While there are actually multiple codons that code for any one amino acid, for this activity there only needs to be one DNA triplet and one corresponding mRNA codon recorded for each amino acid.
