Question

SRY is best described in which of the following ways? A) a gene present on the X chromosome that triggers female development B) an autosomal gene that is required for the expression of genes on the Y chromosome C) a gene region present on the Y chromosome that triggers male development D) an autosomal gene that is required for the expression of genes on the X chromosome E) a gene required for development, and males or females lacking the gene do not survive past early childhood The following questions refer to this table of codons. A possible sequence of nucleotides in the template strand of DNA that would code for the polypeptide sequence phe-leu-ile-val would be A) 5' TTG-CTA-CAG-TAG 3'. B)3' AAC-GAC-GUC-AUA 5'. C) 5' AUG-CTG-CAG-TAT 3' D) 3' AAA-AAT ATA ACA 5'. E) 3' AAA-GAA-TAA-CAA 5'. What amino acid sequence will be generated, based on the following mRNA codon sequence? 5' AUG-UCU-UCG-UUA-UCC-UUG 3' A) met-arg-glu-arg-glu-arg B) met-glu-arg-arg-glu-leu c) met-ser-leu-ser-leu-ser D) met ser ser-leu-ser-leu E) met leu-phe-arg-glu-gl

Explanation / Answer

Answer

8). a gene region present on the Y chromosome that triggers male development

SRY gene present on Y chromosome and they are present only in males. They help in male development.

9).E. 3'AAA-GAA-TAA-CAA 5'

Amino acid. Phe-Leu-ile-Val

mRNA. 5' UUU-CUU-AUU-GUU 3'

DNA template strand. 3' AAA-GAA-TAA-CAA 5'

10). D. met-ser-ser-leu-ser-leu
