The following sentences describe the middle part of a gene found in a template strand of DNA (see template strand DNA in bold below).
The following sentences describe the middle part of a gene found in a template strand of DNA (see template strand DNA in bold below). Use the genetic code given in the figure to complete the sentences, and then arrange the sentences in the correct chronological order. Template strand DNA: 3 TAACGCCGTTCGTCA 5 First letter of codon U - UUUU UUC UUA UUG c| CU CUC CUA CUG A AUU Phenylalanine (Phe: F) Leucine (Leu; L) G GUU GUC GUA GUG -Leucine (Leu; L) AUC-Isoleucine (le:) AUA AUG Start Methionine (Met; M) Valine (Val; V) UCU UCC UCA UCG CCU CCA CCG ACU ACC ACA ACG GCU GCC GCA GCG The Genetic Code Second letter of codon A UAU UAC UAA UAG Serine (Ser; S) -Proline (Pro; P) -Threonine (Thr, T) Alanine (Ala; A) CAU CAC CAA CAG AAU AAC AAA AAG GAU GAC GAA GAG -Tyrosine (Tyr: Y) Stop Stop Histidine (His; H) Glutamine (Gin; Q) -Asparagine (Asn; N) -Lysine (Lys; K) Aspartic acid (Asp; D) -Glutamic acid (Glu; E) G UGU UGC UGA UGG CGU CGC CGA CGG AGU AGC AGA AGG GGU GGC GGA GGG Cysteine (Cys; C) Stop Tryptophan (Trp; W) -Arginine (Arg: R) -Serine (Ser, S) Arginine (Arg: R) -Glycine (Gly, G) SUAU SYNC DCAG SUA Third letter of codon lle-Ala-Ala-Ser-Ser amino acid transcription codon Ser-Ser-Ala-Ala-Thr IRNA elongation AUUGCGGCAAGCAGU Thr-Val-Val-Ser-Arg translation Reset DNA UAACGCCGUUCGUCA ribosome initiation mRNA arilicodon nucleus cytoplasm ATTGCGGCAAGCAGT termination This gene sequence undergoes transcription (i.e., is copied) into mRNA by RNA polymerase and other proteins. This occurs in the nucleus of the cell. Reading from 5 to 3 , this RNA product has the sequence UAACGCCGUUCGUCA. It binds to the small subunit of the ribosome. It is joined by the large subunit, completing the initiation stage of the process of translation. Each mRNA 3-base sequence, called a codon, matches with a tRNA sequence called the anticodon. The tRNA also carries the specified amino acid, used as a building block for a protein. The resulting portion of the polypeptide has this sequence (using the 3-letter codes): Thr-Val-Val-Ser-Arg.
