In which direction will water always flow in a cell?
What is high to low concentration.
100
What is splicing?
What is cutting up DNA molecules and splicing the fragments together
100
How many chromatids are in a duplicated chromosome?
What is 2
100
What happens when organic compounds are broken down into simpler compounds?
What is energy is released
100
Evolution is?
What is the gradual development of a species
200
Why is osmosis important to a cell?
What is it is needed to transport nutrients around the cell.
200
The 5' capping process creates what type of linkage?
What is 3'-5'
200
What happens during prophase?
What is 1. The nucleoli disappear 2. Chromatin fibers coil up to become discrete chromosomes. 3. Each chromosome now consists of two identical sister chromatids 4. Microtubules grow out from the centrosomes
200
What are the products of cellular respiration?
What is CO2, water, and ATP
200
Random evolutionary changes in a small breeding population is known as?
What is genetic drift
300
A solution that has a higher concentration of solute than another solution is called?
What is hypertonic
300
Codons that code for the same amino acid are called?
What is a synonym
300
What happens during metaphase?
What is 1. The mitotic spindle is fully formed 2. The microtubules move the chromosomes to the metaphase plate
300
What are the two stages of cellular respiration?
What is glycolysis and aerobic respiration
300
What process provides the genetic variability that natural selection acts on during evolution?
What is mutation
400
A solution that has a lower concentration of solute than another solution is called
What is hypotonic
400
Adenine and guanine are examples of what class of nitrogen base?
What is purine
400
What happens during anaphase?
What is 1. The two centromeres of each chromosome come apart, separating the sister chromatids. 2.Each sister chromatid is considered a full-fledged daughter chromosome. 3. Motor proteins of the kinetochores move the daughter chromosomes along the spindle microtubules toward opposite poles 4. Microtubules shorten. 5. Spindle microtubules not attached to chromosomes lengthen, pushing the two poles farther apart and elongating the cell.
400
During cellular respiration, what does pyruvic acid undergo when no oxygen is present?
What is fermentation
400
The formation of a new species from an ancestral population?
What is speciation
500
Two solutions that have the same solute concentration are called
What is isotonic
500
What signals the end of transcription?
What is a stop codon
500
What happens during Telophase?
What is 1. Nuclear envelopes form around the identical sets of chromosomes at the two poles of the cell. 2. Chromosomes uncoil 3. Nucleoli appear in the two new nuclei. 4. Cytokinesis begins, splitting the cytoplasm and separating the two daughter cells.
500
What are the two stages of aerobic respiration?
What is the Krebs Cycle and the Electron Transport Chain
500
Evolution that involves changes in allele frequencies over just a few successive generations is referred to as?
What is natural selection
