Which student accurately describes the products of mitosis?
Student 1
Student 2
Student 3
Student 4
At a point in the cell cycle, chromosomes have aligned near the middle of a cell. Which sequence of events will the cell need to complete to produce two identical daughter cells?
anaphase telophase cytokinesis
anaphase II telophase II cytokinesis II
prophase metaphase anaphase
metaphase II anaphase II telophase II
Which event describes cellular activities that would be observed during cytokinesis in an animal cell?
The cytoplasm of the parent cell divides following the division of the nucleus
The chromosomes line up at the equator of the spindle in their most tightly condensed form
The DNA and proteins condense and the centrioles move toward the opposite ends of the cell to form a spindle
The spindle fibers, attached to the two sister chromatids of each chromosome, contract and separate as the chromosomes move to opposite poles of the cell
Which student correctly compared the outcomes of meiosis and mitosis?
Student 1
Student 2
Student 3
Student 4
Which process helps to preserve the genetic information stored in DNA during DNA replication?
The replacement of nitrogen base thymine with uracil
Enzymes quickly linking nitrogen bases with hydrogen bonds
The synthesis of unique sugar and phosphate molecules for each nucleotide
Nucleotides lining up along the template strand according to base pairing rules
Which statement describes a cell process that is common to both eukaryotic and prokaryotic cells?
Both cell types carry out transcription in the nucleus
Both cell types use ribosomes to carry out translation
Both cell types assemble amino acids to carry out transcription
Both cell types carry out translation in the endoplasmic reticulum
Which statement best describes how organisms use DNA and amino acids to synthesize a
protein?
DNA is transcribed into mRNA, which is translated by the ribosome to produce an
amino acid chain.
DNA is translated into mRNA, which is transcribed by the ribosome to produce an
amino acid chain.
Amino acids are transcribed into mRNA, which is translated in the nucleus to produce a
molecule of DNA.
Amino acids are translated into mRNA, which is transcribed in the nucleus to produce a
molecule of DNA.
Which mutation would most likely affect the organism’s phenotype?
A genetic mutation resulted in a change in the sequence of amino acids of a protein, but the function of the protein was not changed. Which statement best describes the genetic mutation?
It was a silent mutation that caused a change in the DNA of the organism
It was a silent mutation that caused a change in the phenotype of the organism
It was a nonsense mutation that caused a change in the DNA of the organism
It was a nonsense mutation that caused a change in the phenotype of the organism
A section of DNA in a cell is altered. Which mutation is being illustrated in the DNA section in the diagram?
deletion
insertion
duplication
nondisjunction
