Flashcards in Storing and Using Genetic Info Deck (13):
1

Each nucleotide of DNA contains

phosphate, sugar (2-deoxribose), nitrogen containing base
In RNA, sugar = ribose

2

Purines

adenine (A) and guanine (G)

3

Pyridimines

thymine (T) and cytosine (C),

4

2 properties of DNA

semi-conservative (1 parental/1daughter) and bidirectional (new strands grow different direction 5 to 3)

5

Different codons specify the same amino acid

Degeneracy/redundancy of genetic code

6

coding regions

exons (transcription)

7

non-coding regions

introns (transcription)

8

Which chromatin has active genes?

euchromatin

9

where does transcription occur?

nucleus
make mRNA (RNA polymerase)

10

where does translation occur?

cytoplasm
info contained in mRNA used to make polypeptide

11

Difference between normal Hb and sickle cell

mutation of single nucleotide
coding strand GAG to GTG
template strand GUG
GLU to VAL (6)

12

continuous - DNA polymerase
coding strand - 3' to 5'
template strand - 5' to 3'

Lagging strand

13

One gene can code more than 1 protein

alternative splicing
