DNA
Rafael Izas Liard
| Question | Answer |
|---|---|
| deoxyribonucleic acid | -molecule found in the neucleus that acts as instructions that determine everything about a cell(what type of cell, how it functions, and how long it will live) -DNA can take the form of chromatin or it can coil up to create chromosomes |
| chromatin | it is located within the neucleus and it's purpose is to create chromosomes it is cruisial in cell division |
| chromosomes | every animal and plant species has a specific amount of chromosomes the size of the organism doesn't affect the number of chromosomes they come in pairs, one from your father and the other one from your mother it's a compact form of DNA that is |
| nitrogen base pairs | there are 4 types of nitrogen bases and each one can pair with a specific other base adenine pairs with thymine guanine pairs with cytosine |
| adenine | its one of the nitrogen base pairs used to create DNA it also is used to store energy in the cell it can only pair with thymine |
| thymine | it is one of the 4 types of nitrogen bases and can only pair with adenine it's aslo the main stabilizer in the dna ladder to ensure that it will have a soldi fondation |
| cytosine | it's one of the 4 types of nitrogen bases and can only pair with guanine |
| guanine | it's one of the 4 types of nitrogen bases and can only pair with cytosine |
| double helix | it's a structure formed by double starnded molecules of nucleic acids the double helix formation contains all the information to create new cells and is needed for cell replication |
| gene | a segment of nitrogen base pairs forms a gene most genes contain 1000s of nucleotides they hold the instrutions on how to make proteins |
| nucleotide | they are made from phosphate molecules, nitrogen base pairs, and sugar molecules combined they also hep create proteins |
| catalyze | a verb meaning to accelerate a process |
| enzymes | they are a type of protein that speeds up the rate of chemical reactions within a cell |
| genetic screening | the process of testing a population for a genetic disease in order to identify a group of people that have or have the potential of spreading the disease |
| genetically modified organisms | they are organisms that have had their genes modified in order to promote protein production |
| transgenic organisms | they are used to solve problems like protecting crops form bugs there is no proof that they don't have negative effects organs from transgenic pigs are used for human transplants which could lead to humans contracting pig diseases |
| mutagen | it is a cause for mutations such as radiation or harmful chemicals |
| mutation | mutations are a result of a new protein being created which is caused by a change in the neucleotide sequence they can be very harmful and cause issues such as cancer and problems in reproduction but they can also have to effect at all or have a posi |
