what 3 componants make up a nucleodtide in DNA?
Deoxyribose, Nitrogenous base, Phosphate group
2 of 16
what enzyme unzips the DNA strand?
DNA Helicase
3 of 16
How many base pairs in one full turn of the double helix?
10
4 of 16
how many possible combinations of the 4 bases are there?
64
5 of 16
what bond forms between the base and sugar?
glycosidic
6 of 16
what bond forms between the sugar and phospate group?
phosphodiester
7 of 16
where do mRNA and tRNA meet?
in the ribosome
8 of 16
what bond forms between the bases and how many depending on the bases?
hydrogen bonds. 3 in G-C and 2 in T-A
9 of 16
what are the purine bases?
Guanine and Adenine
10 of 16
what enzyme is in the ribosomes?
Peptidyl transferase
11 of 16
what are the pyramidine bases?
Thymine, Cytosine, Uracil
12 of 16
what are the three types of RNA
mRNA, tRNA, rRNA
13 of 16
whats transcription?
when the DNA double helix splits the free RNA nucleotides in the cytoplasm bind to the DNA bases to form an mRNA strand which will then be edited and can be sent out the nucleus
14 of 16
where do you find the anticodon?
tRNA
15 of 16
what is the role of tRNA
the anticodon it has matches a triplet code of the mRNA and has a specific amino acid attached, it bonds all the amino acids together through peptide bonds to form a primary structure of protein
