(46 cards)
Complementary bases of DNA
Adenine thymine cytosine guanine
Where is DNA found
Nucleus
Decribe structure of DNA
Sugar+phosphate +nitrogen bases making the leaders
Where does DNA replication occurs ?
In the nucleus
What does a semi conservative DNA means?
After replication the new DNA is compose of a new strand and KEEPS an old one
What mutation in DNA ?
A change in the DNA sequence
What would be the other side of this DNA sequence
ATTCGGCATC
TAAGCCGTAG
What are the building blocks of DNA
Nucleotides
Why can’t DNA leave the nucleus ?
It’s too big
Define transcription
Process of creating a complementary RNA copy of DNA
It makes mRNA, rRNA, tRNA and other protein complements
What is the proces of translation?
RNA is decoded by the ribosome to produce specific amino acid, that becomes protein
Describe tree toipes of mutation
- addition-adding one or more base pair into DNA secuency
- deletion-deleting one or more base to a DNA sequence
- substitution-changing a base pair into a different base pair
Are any mutations beneficial ?
Yes. Is the main force of evolution
What cellular proces does cancer take over?
Cell division
mRNA sequence of
ACA TAC AAA TGG ATC
UGU AUG UUU ACC UAG
Transport amino-acidsto the ribosome ?
tRNA
Recombinant DNA
DNA that result from the use of laboratory methods to bring genetic material from multiple sources
Restriction enzime
Cuts DNA at specific recognition nucleotide
Recognition site
Specific base where restriction enzime makes a cut
Levels of taxonomy from biggest to smallest
Kingdom, phylum, class, order, family, genus, species
Name the six kingdoms
Eubacteria, archea, protista, fungi, plants, animalia
Autotrophs
Organism that can capture energy from the sunlight and convert it into chemical energy
Reproductive cells of fungi
Spores
Name bacteria and method of movement
Amoeba-pseudopods
Euglena-flagella
Paramecium-cilia
