Flashcards in 2/7/17 lecture: molectural genetics I Deck (15):
1

phylogenetics

the reconstruction of evolutionary relationships

2

law of parsimony

simplest explanation

3

dna character

position in sequence

4

dna character states

A, T, C, G

5

hemaphrodites

intersex, both gameets

6

hypodemic mating

inject sperm into one ut doesnt get sperm back - choosy

7

reciprocal mating strategy

both come together, exchange sperm

8

DNA

dexoyribonucleic acid, molecule of heredity, anything living uses DNA as moleule of heredity - DNA just stores info

9

rna

ribonucleic acid, transcription - making copy of a gene- DNA is used by others- DNA itself is copied

10

Gene

sequence of nucleotide - building blocks encoding a speciic sequence of amino acids - polypeptide, sequence of nucelotides that is transcribbed, region of DNA expressed to produce final product

11

builiding blocks of proteins

amino acids ie hemoglobin - carries oxygen from lungs to tissue- cellular respriation

12

central dogma of molecular biology

DNA --> RNA --> protein

13

transcription

take from one form to another - info from DNA to RNA nucelic acids

14

translation

producing - translating - going from nucleic acids to amino acids

15

structure of DNA

double helix ladder, outer sides are sugar phospahte backbones - ladder side; rungs are nitrogenous bases, weak hydrogen bonds
