Genetic-material Sentence Examples

Ray Lankester's term, homoplasy, has passed into currency as designating such cases where different genetic material has been pressed by similar conditions into similar moulds.

If we look at style as an organism, style-markers are its genetic material - making this project analogous to the human genome project.

As the tube grows, the contents of the pollen grain - essentially genetic material - passes down the tube.

Alien genetic material invading genomes also give rise to gene mutations, some of which may result in cancer.

Therefore mutation provides a mechanism for adding random genetic material into the chromosome by changing one or more of the gene values at random.

Foreign genetic material can also be introduced into plant and animal cells by insects and arthropods with sharp mouthparts.

Vegetative reproduction - a reproductive process that is asexual and so does not involve a recombination of genetic material.

Recombinant A cell or organism formed by the rearrangement of genetic material from different sources.

Within the cell, the viral RNA is replicated entirely in the cytoplasm, outside the nucleus containing the cell's own genetic material.

The other fuses with genetic material in the ovule to produce a triploid tissue (has three copies of each chromosome).

Mutation-A permanent change in the genetic material that may alter a trait or characteristic of an individual, or manifest as disease.

Virus-A small infectious agent consisting of a core of genetic material (DNA or RNA) surrounded by a shell of protein.

The first diagnosis of a mitochondrial disorder occurred in 1959, and the genetic material of microchondria, called mtDNA, was discovered in 1963.

Genetic defects may be passed through nuclear DNA (nDNA), the genetic material found in each cell that determines the majority of hereditary characteristics, or through mtDNA.

Chromosomes are made up of hundreds of small units known as genes, which contain the genetic material necessary for an individual to develop and function.

Identical twins will have the same DNA, genetic material (genotype), but it may be expressed differently (phenotype).

The zygote is a single cell that contains the genetic material of both the mother and the father.

Mitochondria contain genetic material (DNA and RNA) and are responsible for converting food to energy.

Alkylating drugs-kill cancer cells by directly attacking DNA, the genetic material of the genes.

Alkylating agent-A chemical that alters the composition of the genetic material of rapidly dividing cells, such as cancer cells, causing selective cell death; used as a chemotherapeutic agent.

The sample of amniotic fluid is sent to a laboratory where fetal cells contained in the fluid are isolated and grown in order to provide enough genetic material for testing.

Because both parents contribute genetic material to their offspring, each child carries two copies of almost every gene, one from each parent.

The genetic material of the sperm and egg then combine to form a single cell called a zygote and the germinal stage of prenatal development commences.

Cri du chat syndrome is also called 5p minus syndrome or chromosome 5p deletion syndrome because it is caused by a deletion, or removal, of genetic material from chromosome 5.

This deleted genetic material is vital for normal development.

A deletion occurs when the genetic material in the chromosomes does not recombine properly during the formation of sperm or egg cells.

Deletion-The absence of genetic material that is normally found in a chromosome.

Often, the genetic material is missing due to an error in replication of an egg or sperm cell.

Initially, scientists found that individuals with PWS have a portion of genetic material deleted (erased) from chromosome 15.

In order to have PWS, the genetic material must be deleted from the chromosome 15 received from one's father.

Over time, scientists realized that some individuals with PWS do not have genetic material deleted from chromosome 15.

A small number of patients with PWS have a change (mutation) in the genetic material on the chromosome 15 inherited from their father.

Traditional DNA testing looks at the information contained in the nucleus, but mitochondrial DNA testing examines the genetic material in the mitochondria themselves.

It was this scientist who first suggested genetic material could be removed from a cell and used to create another adult.

This experiment's premise was to prove genetic material is not lost as cells grow and divide.
