In e. coli a particular trna normally has the anticodon5’-ggg-3’, but because of a mutation in the trna gene, the mutant trna has the anticodon 5’-gga-3’.a. what amino acid would the wildtype trna carry? b. what amino acid would the mutant trna carry? c. what codon would the normal trna recognize? d. what codon would the mutant trna recognize? e. what would be the effect of the mutation of the proteinsin the cell

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.

In the diagram below, the northern hemisphere would be in what season at position a a.fall b. winter c.summer d.spring

How can a geological time scale best be reconstructed? a) comparing vestigial structures in living species b) comparing homologous structures in living species c) examining homologous structures in fossil remains d) examining the written records of scientists from past cultures
