The Biology Of Reproduction Quiz

Information processing

Stabilizing the structure of the nuclear envelope

Connecting chromatids together at the centromere

Forming the spindle apparatus at cell division

segment of protein that carries information

Segment of protein that acts as an enzyme to carry out processes coded in the information contained in the nucleus

A segment of DNA that encodes information for the metabolism or reproduction of a cell or organism

A conceptual scheme that guides research but has no real meaning in the context of a cell

Phosphate group

Itrogenous base, either A, T, C, G, or U

5-carbon sugar: deoxyribose or ribose

amino acid

cholesterol

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

Ribosomes

Cell membrane

Bacterial RNA

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.

Haplotypes; karyotypes

Genotype; phenotype

Phenotype; genotype

allele; locus

Homozygous dominant = 1heterozygous = 4homozygous recessive = 3

homozygous dominant = 4heterozygous = 1homozygous recessive = 3

Homozygous dominant = 1heterozygous = 3homozygous recessive = 4

homozygous dominant =3heterozygous = 4homozygous recessive = 1

genotypes: all rrphenotypes: all white

genotypes: 1/2 RR: 1/2 Rrphenotypes: all red

Genotypes: 1/2 RR: 1/2 Rrphenotypes: 1/2 red; 1/2 white

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
