Prokaryotic cells contain ________ chromosome within a nucleus.

During this phase, sister chromatids of each chromosome, held together only at their centromere regions, disjoin (separate) from one another and are pulled to opposite ends of the cell.

_______________ replication describes the mechanism of DNA replication in all known cells.

Variants of a gene controlling the same trait and occupying a specific region on a chromosome.

The dense, constricted region containing highly-specialized repetitive DNA sequence, and functions chiefly by joining the two sister chromatids that make up the X-shaped chromosome and by serving as a site for kinetochore assembly during cell division.

Molecules that act as temporary carriers of amino acids, bringing the appropriate amino acids to the ribosome based on the messenger RNA (mRNA) nucleotide sequence.

Organic compounds that contain amine and carboxyl functional groups, along with a side chain specific to each one.

Sequence of three RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis.

Mitosis leads to the production of _______ cells, each with the same number of chromosomes as the parent cell. Strictly speaking, mitosis is that portion of the cell cycle during which the hereditary components are equally partitioned into daughter cells.

Mitosis leads to the production of two cells, each with the same number of _______ as the parent cell. Strictly speaking, mitosis is that portion of the cell cycle during which the hereditary components are equally partitioned into daughter cells.

Fred Griffith was famous for his research on:

DNA ____________ is the biological process of producing two identical replicas of DNA from one original DNA molecule.

Meiosis reduces the genetic content and the number of chromosomes by precisely _______. This reduction is essential if sexual reproduction is to occur without doubling the amount of genetic material in each new generation. Meiosis is part of a special type of cell division that leads to the production of sex cells: gametes or spores.

Meiosis reduces the genetic content and the number of chromosomes by precisely one half. This reduction is essential if _______ reproduction is to occur without doubling the amount of genetic material in each new generation. Meiosis is part of a special type of cell division that leads to the production of sex cells: gametes or spores.

Deoxyribonucleic acid, better known as DNA, stores hereditary information in small segments called histones.

Deoxyribose is a ribose derivative in which an oxygen atom is missing from one carbon; the carbon was deoxygenated.

A 5-carbon sugar (ribose or deoxyribose) forms the central molecule in a nucleotide.

Each nucleotide is composed of three parts: a 5-carbon sugar, a methyl group, and a nitrogenous base.

Adenine always pairs with thymine.

Purines include which of the following:

Pyrimidines include which of the following:

In Hershey and Chase's experiment, radioactively labeled _______ was used to identify the protein in the virus, because most proteins contain some amino acids with this element in their R-groups.Radioactively labeled phosphorus was used to tag the DNA as this element is found in all nucleotides.

In Hershey and Chase's experiment, radioactively labeled sulfur was used to identify the _______ in the virus, because most proteins contain some amino acids with this element in their R-groups.Radioactively labeled phosphorus was used to tag the DNA as this element is found in all nucleotides.

On every nucleotide, a phosphate group is attached to the 5’ carbon position, the carbon atom that is outside the sugar ring.

Nucleic acids are polymers of individual nucleotide monomers.

Some RNA molecules, such as tRNA and rRNA, are active, three-dimensional products that provide enzymatic or regulatory functions.

DNA is less stable than RNA because it contains one less reactive oxygen atom.
