DNA AND RNA Flashcards
The 2 scientist that found out that DNA as a double helix
James Watson and Francis Crick
RNA
Ribonucleic acid
—- uses the information from mRNA to make more proteins
translation
where can you find anti codons?
on one end of tRNA
—- used to carry genetic info from DNA to the ribosome
mRNA
Jelly like structure in a cell
cytoplasm
Genetic code
Corresponds to the nucleotide triplets which forms the amino acids which is the base of proteins
what are the complementary pairs of codons?
anticodons
what are codons made out of?
nitrogen bases
triplets of nitrogen bases that code for amino acids are called?
codons
Termination: Step 3 in translation
this is when the tRNA runs into the stop codon: UAA, UAG, UGA (none are amino acids). The ribosome attaches the last amino acid that will serve as the protein and it will be sent to the cytoplasm to undegro modification. Lastly, the ribosome breaks of the mRNA starnd.
Initiation: S1 in protein synthesis
Enzyme called RNA polymerase binds to promoter (an area in the DNA) this signals the DNA to unwinds so that the enzyme can read its strands. RNA polymerase will make an mRNA strand.
what do you call the arrangement of the DNA and RNA codes?
genes
monomer of nucleic acids
nucleotide
the process of using an existing DNA to make a new DNA
DNA replication
making a new copy of DNA
replication
what codon signals the start of translation?
AUG= methionine
amino acid
basic unit of protein
Order of DNA replication
- Helicase begins to break the hydrogen binds between nitrogen bases
- Free floating nucleotide pair up with the exposed nitrogen bases
- DNA polymerase attach the free floating nucleotides to the exposed nitrogen bases
- Two molecules of DNA are created
- Cell starts into the mitosis parts of the cell
transcription occurs in the —-
nucleus
where can you find codons?
the strand of the mRNA
proteins are made in the —-
ribosome
theory that genetic information flows in one direction from DNA to RNA to protein.
central dogma
what are the 2 steps of protein synthesis
Initiation and Translation
