A mutation that occurs in the gametes of an organism will most likely be transferred to which of the following?
The siblings of the organism
The offspring of the organism
The other organisms living nearby
The mating partner of the organism
What is the purpose of this cellular process
Preserving genetic information for future generations
Deleting the information in the sequence produced from the DNA template
Transcribing information in the DNA sequence for the use by the cell
Producing more nucleotides for the DNA sequence
What is the purpose of this process?
To replicate the DNA of an organism before cell division
To assemble nucleotides in an mRNA chain along a DNA template
To synthesize amino acids used to unzip strands of DNA and copy the genetic code
To translate the genetic code into a specific sequence of amino acids
What characteristic is shared by all four cells?
A mechanism for transforming sunlight into energy
Self-locomotion
Membrane-bound organelles that transport substances
Genetic material composed of DNA
Which DNA strand is complementary to the one shown above?
Human bone, muscle, and nerve cells all contain the same number of chromosomes with the same complement of genes. What enables these cells to perform specialized activities?
The ability of some cells to remove unnecessary DNA sequences
The regulation of gene expression within each cell type
The mutation of genes within each cell type
The use of different methods of cell division.
The process represented in the diagram produces a molecule that is complementary to the template strand of DNA. What type of molecules is produced.
New DNA
Polypeptide
Messenger RNA
Carbohydrate
What causes this change in fur color?
The alleles for fur color change as the arctic fox grows older.
Gene expression for fur color is regulated by latitude.
The arctic fox has two traits for fur color that are determined at birth.
Gene expression for fur color is regulated by temperature.
Which process and product are represented in Diagram 2
Process: transcription; product: mRNA
Process: translation; product: protein
Process: replication; product: tRNA
Process: recombination; product: polymerase
Early-onset Alzheimer's disease affects people under the age of 65. Less than 5% of people who are diagnosed with Alzheimer's disease have this type. Many cases of early-onset Alzheimer's disease are inherited, a type known as familial Alzheimer's disease (FAD). Which statement is best supported by this information?
FAD is the result of a genetic change in one or more chromosomes.
Natural selection will continue to reduce the incidence of FAD.
FAD affects only the genes of middle-aged people.
Deletion of one amino acid causes FAD.
