What stage of interphase does DNA replication occur?
G1
S
G2
What do the blue and yellow arrows represent
The blue arrow is prophase and the yellow is interphase
The blue arrow is mitosis and the yellow arrow is meiosis
The blue arrow is interphase and the yellow is mitosis
The blue arrow is meiosis and the yellow is prophase
Crossing over occurs during prophase I of meiosis. Which statement about crossing over is true?
RNA translation occurs in the smooth endoplasmic reticulum
Crossing over takes place in backterial cells
Crossing over produces genetically identical daughter cells
Crossing over provides genetic diversity in eukaryotic cells
Embryonic cells each have an identical copy of DNA. If the DNA in all cells is identical, how do the embryonic cells become specialized (ex: Muscle cell, brain cell, liver cell, etc)
Each cell contains only the active parts of the DNA needed for the cell type
Each cell type has only one chromosome containing the DNA needed for that cell type
Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to cell variety
If a person has leukemia, they are given a medicine that inhibits (stops) DNA synthesis. Which phase of the cell cycle will be most affected by this medicine?
G1
S
G2
M phase
Which of the following are in order from smallest to largest
Cells -> tissue -> organ -> organ system
Cells -> Organ system -> tissue -> organ
Organ system -> Organ -> Tissue -> Cell
Tissue -> organ system -> Cell -> Organ
What does the image demonstrate
Punnet squares
Crossing over
Metaphase
Dna replication
During prophase I crossing over occurs and genetic material is exchanged between homologous chromosomes. How is this important
Increases genetic variation
Reduces the diploid number to the haploid number
Increases the haploid number to the diploid number
Reduces the probability of mutations
In mitosis, one parent cell -
Forms two identical daughter cells
Forms four identical daughter cells
Forms two genetically diverse daughter cells
Forms four genetically diverse daughter cells
G1, S, and G2 are all phases of
Mitosis
Meiosis
Interphase
Prophase
