|---|---|---|---|---|---|
| Alleles | one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
🗑
|
||||
| Heredity | The passing of genetic factors from parent to offspring (or from one generation to the next).
🗑
|
||||
| Trait | a distinguishing quality or characteristic, typically one belonging to a person.a genetically determined characteristic.
🗑
|
||||
| Recessive | relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents, i.e., when not masked by a dominant characteristic inherited from one parent.
🗑
|
||||
| Dominant | most important, powerful, or influential.
🗑
|
||||
| Phenotype | the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
🗑
|
||||
| Genotype | the genetic constitution of an individual organism.
🗑
|
||||
| Homozygous | Heterozygous means having one each of two different alleles.
🗑
|
||||
| Heterozygous | The genetics term heterozygous refers to a pair of genes where one is dominant and one is recessive — they're different.
🗑
|
||||
| Mutation | A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene.
🗑
|
||||
| replication | he process of duplicating or producing an exact copy of a polynucleotide strand such as DNA.
🗑
|
||||
| nucleotide | a compound consisting of a nucleoside linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA.
🗑
|
||||
| Transcription | The process of transcribing or making a copy of genetic information stored in a DNA strand into a complementary strand of RNA (messenger RNA or mRNA) with the aid of RNA polymerases.
🗑
|
||||
| translation | Translation is a step in protein biosynthesis wherein the genetic code carried by mRNA is decoded to produce the specific sequence of amino acids in a polypeptide chain.
🗑
|
||||
| Karyotyping | the determination of a karyotype, e.g., to detect chromosomal abnormalities.
🗑
|
||||
| codon | a sequence of three nucleotides that together form a unit of genetic code in a DNA or RNA molecule.
🗑
|
||||
| anticodon | a sequence of three nucleotides forming a unit of genetic code in a transfer RNA molecule, corresponding to a complementary codon in messenger RNA.
🗑
|
||||
| Recombinant DNA | DNA that has been formed artificially by combining constituents from different organisms.
🗑
|
||||
| Restriction enzyme | an enzyme produced chiefly by certain bacteria, having the property of cleaving DNA molecules at or near a specific sequence of bases.
🗑
|
||||
| Genetic engineering | the deliberate modification of the characteristics of an organism by manipulating its genetic material.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
