Unit 6 vocab

TermDefinition
DNA Replication the biological process of producing two identical replicas of DNA from one original DNA molecule
Replication Fork s a structure that forms within the long helical DNA during DNA replication. It is created by helicases, which break the hydrogen bonds holding the two DNA strands together in the helix.
Semiconservative - in regards to DNA replication occurs separately on each template strand in antiparallel directions.
Alternative Splicing a process that enables a messenger RNA (mRNA) to direct synthesis of different protein variants (isoforms) that may have different cellular functions or properties.
Exon any part of a gene that will encode a part of the final mature RNA produced by that gene after introns have been removed by RNA splicing.
Intron a segment of a DNA or RNA molecule which does not code for proteins and interrupts the sequence of genes.
Splicing join or connect (a rope or ropes) by interweaving the strands.
Template Strand the DNA strand whose base sequence is identical to the base sequence of the RNA transcript produced.
Transcription the process of copying a segment of DNA into RNA
Codon a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule.
Retrovirus a virus that uses RNA as its genetic material
Translation is the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus.
Virus a submicroscopic infectious agent that replicates only inside the living cells of an organism.
Cell Differentiation the process in which a cell changes from one cell type to another.
Cell Specialization is the process by which generic cells change into specific cells meant to do certain tasks within the body.
Epigenetics the study of heritable changes in gene expression (active versus inactive genes) that do not involve changes to the underlying DNA sequence
Gene Expression the process by which the instructions in our DNA are converted into a functional product, such as a protein.
Histone any of a group of basic proteins found in chromatin.
Operon a sequence of DNA containing a cluster of genes under the control of a single promoter.
Promoter a sequence of DNA to which proteins bind that initiate transcription of a single RNA from the DNA downstream of it.
Transcription Factor a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence.
Conjugation the temporary union of two bacteria or unicellular organisms for the exchange of genetic material.
Host Cell an animal or plant on or in which a parasite or commensal organism lives.
Sterility inability to affect sexual reproduction in a living thing, members of whose kind have been produced sexually.
Tranduction the process by which foreign DNA is introduced into a cell by a virus or viral vector.
Transformation a thorough or dramatic change in form or appearance.
Transposition the genes are transferred from one organism to another through copying and inserting process.
Triploidy a rare chromosomal abnormality in which fetuses are born with an extra set of chromosomes in their cells.
Biotechnology the exploitation of biological processes for industrial and other purposes, especially the genetic manipulation of microorganisms for the production of antibiotics, hormones, etc.
DNA Sequencing the process of determining the nucleic acid sequence
Electrophoresis the movement of charged particles in a fluid or gel under the influence of an electric field.
Genetic Engineering process of using recombinant DNA (rDNA) technology to alter the genetic makeup of an organism.
Polymerase Chain Reaction (PCR) is a method widely used to rapidly make millions to billions of copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detail.

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.
