Reproduction Defs

Exploring Creation with Biology - Module 7 (Cellular Reproduction) Definitions

QuestionAnswer
Genetics The science that studies how characteristics get passed from parent to offspring
Genetic factors The general guideline of traits determined by a person's DNA
Environmental factors Those "non-biological" factors that are involved in a person's surroundings such as the nature of the person's parents, the person's friends, and the person's behavioral choices
Spiritual factors The quality of a person's relationship with God
Gene A section of DNA that codes for the production of a protein or a portion of a protein, thereby causing a trait
Chromosome A strand of DNA coiled around and supported by proteins, found in the nucleus of the cell
Mitosis The duplication of a cell's chromosomes to allow daughter cells to receive the exact genetic makeup of the parent cell
Interphase The time interval between cellular reproduction
Centromere Constricted region of a chromosome and the point at which duplicate DNA strands attach themselves
Mother cell A cell ready to begin reproduction, containing duplicate DNA and centriole
Karyotype The figure produced when the chromosomes of a species during metaphase are arranged according to size
Diploid cell A cell whose chromosomes come in homologous pairs
Haploid cells Cells that have only one of each chromosome
Diploid chromosome number The total number of chromosomes in a diploid cell
Haploid chromosome number The number of homologous pairs in a diploid cell
Meiosis The process by which a diploid (2n) cell forms four gametes (n)
Gametes Haploid cells (n) produced by diploid cells (2n) for the purpose of reproduction
Virus A non-cellular infectious agent that has two characteristics: (1) It has genetic material inside a protective protein coat; (2) It cannot reproduce itself
Antibodies Specialized proteins that aid in destroying infectious agents
Vaccine A weakened or inactive version of a virus that stimulates the body's production of antibodies which can destroy the virus

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
