- The 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.A gene contains the sequence CGCATACGGTAC that results in the amino acid sequence arg-ile-arg-tyr. A mutation in this gene removes the first G in the strand.What is true of this mutation's effect on the phenotype?1.It will affect the phenotype because although most of the protein will be identical, the first amino acid will be different.2.It will not affect the phenotype because the protein will be identical to the original protein.3.It will affect the phenotype because all the amino acids past this point will be different from the original protein.4.It will not affect the phenotype because only the first amino acid is different from the original protein.Which of the following does cytosine pair with?a. guanineb. thyminec. adenined. a pyrimidine

Asp to Glu Asn to Glu Cys to Lys Pro to Gly Val to ThrIf an extra nucleotide is inserted in the first exon of the beta globin gene, what effect will it have on the amino acid sequence of the globin polypeptides? Will the globin most likely be fully functional, partly functional, or nonfunctional? Why?
- Identify the features of tRNA that are important in decoding genetic information and converting it into protein language.Which of the following does cytosine pair with? a. guanine b. thymine c. adenine d. a pyrimidineA certain mRNA strand has the following nucleotide sequence: 5AUGACGUAUAACUUU3 What is the anticodon for each codon? What is the amino acid sequence of the polypeptide? (Use Figure 13-5 to help answer this question.) Figure 13-5 The genetic code The genetic code specifies all possible combinations of the three bases that compose codons in mRNA. Of the 64 possible codons, 61 specify amino acids (see Figure 3-17 for an explanation of abbreviations). The codon AUG specifies the amino acid methionine and also signals the ribosome to initiate translation (start). Three codonsUAA, UGA, and UAGdo not specify amino acids; they terminate polypeptide synthesis (stop).
