A conceptual scheme that guides research but has no real meaning in the context of a cell
Itrogenous base, either A, T, C, G, or U
5-carbon sugar: deoxyribose or ribose
Its structure was discovered by two workers, James Watson and Francis Crick, a doubling of research effort at a building informally called the "Helix" at Cambridge University.
DNA is double stranded, with the two strands both in the form of a helix entwined around each other like strands of a rope.
When DNA interacts with RNA, the two molecules form a twisted double strand.
It seemed like a catchy name even though it has nothing to do with the structure of DNA.
DNA contains ribose, RNA contains deoxyribose.
DNA is double-stranded, RNA is single stranded.
DNA is single-stranded, RNA is double-stranded
DNA and RNA both contain the bases A, T, C, and G
The formation of protein by enzymes at the Golgi apparatus in a specialized cells
The formation of DNA prior to cell division
The process of secretion of proteins from a cell vi th Golgi apparatus
The formation of RNA using DNA as a template
A sequence of three amino acids that codes for a specific type of RNA in a ribosome
three-based sequence on an RNA that codes for a specific amino acid
specific portion of a ribosome that attaches to a membrane
Another term for a gene
in the nucleus
In the smooth endoplasmic reticulum
In the cytoplasm on ribosomes
on the inner surface of the cell membrane
In the nucleolus
A single base difference in the DNA results in a change in the structure of hemoglobin
A rearrangement of DNA in the chromosome results in a mismatch between the RNA and DNA, thus altering the makeup of hemoglobin
RNA is altered by the point mutation such that it cannot be translated
DNA is altered by the point mutation such that is cannot be transcribed.
Spindle fibersspindle fibers
They are identical
They have complementary structures.
They carry differnet genetic information
The are homolgous
Before division, chromosomes are short, thick, and condensed; during division, chromosomes are long, thin, and diffuse
Before division, chromosomes are long, thin, and diffuse; during division, chromosomes are short, thick, and condensed
Before division, chromosomes are made of RNA; during division, chromsomes convert to DNA
Before division, chromosomes are made of DNA; during division, chromsomes convert to RNA.
Each chromosome carries a unique subset of information in the cell, just as a chapter in a book carries a unique subset of the book's information
Chapters in a book are sequential in information; so are chromosomes
Chapters in a book must all have the same author, just as chromosomes must all be from the same organism
All of the above are correct
Chromosomes that have been altered by mutations.
Chromsomes that always have only one chromatid and never duplicate.
Paired chromosomes,which are derived from the two parents - one from the mother, one from the father.
Chromosomes that are not paired with any other chromosome but carry identical genetic information
the spindle fibers form
the chromosomes line up at the cell equator
The nuclear envelope disappears
Answers 1 and 2 are correct
Answers 1 and 3 are correct
Answers 2 and 3 are correct
In meiosis, synapsis occurs; synapsis does not occur in mitosis
In mitosis synapsis occurs; synapsis does not occur during meiosis.
In mitosis, the nuclear envelope disappears; in meiosis it does not disappear.
In mitosis, the nuclear envelope does not disappear; in meiosis it does disappear
Prophase; prophase I
Metphase; metaphase II
Anaphase; anaphase II
Telophase; telophase I
Reproduction involving two parents who each contribute all of their genetic information to form an offspring.
Reproduction involving one parent who contributes one-half of its genetic information to form an offspring.
Reproduction involving one parent who contributes all of their genetic information to form an offspring
Aseuxal reproduction is another term for meiosis.
Homozygous dominant = 1heterozygous = 4homozygous recessive = 3
homozygous dominant = 4heterozygous = 1homozygous recessive = 3
Homozygous dominant = 1heterozygous = 3homozygous recessive = 4
homozygous dominant =3heterozygous = 4homozygous recessive = 1

An exchange of pieces of chromatid between homologous chromsomes during meiosis
An exchange of pieces of chromatid between homologous chromsomes during mitosis
an exchange of pieces of chromatid between non homologous chromsomes during meiosis
an exchange of pieces of chromatid between nonhomologous chromsomes during mitosis
These traits tend to be more lethal in female embryos than in males, so you will see more males with the trait.
These traits are simply not inherited by females due to sexual selection in meiosis.
Males have only one copy of the allele because it is carried on the X-chromosome. Females have two alleles for these traits
There is no known explanation for this observation
Male pattern baldness is sex-influenced, with a combination of male hormones and genetics affecting pattern baldness
Male pattern baldness is sex-linked, which means that more men will have the trait
Male pattern baldness is caused by a disease to which men are more prone
There is no known explanation for this phenomenon
