GENE EXPRESSION EUKARYOTIC

Question 1

histone acetylation

Answer 1

adds acetylation groups to histones, which loosens the DNA

Question 2

histone

Answer 2

provides structural support for the protein

Question 3

dna methylation

Answer 3

adds methyl groups to DNA, which causes the chromatin to condense

Question 4

EPIGENETIC INHERITANCE

Answer 4

chromatin modification do not alter the nucleotide sequence of the DNA, but they can be heritable for future generations
-modifications can be reversed, but mutations cannot

Question 5

TRANSCRIPTION INITIATION

Answer 5

chromatin modifications allow the DNA to be more accessible, specific transcription factors bind to control elements

Question 6

RNA processing

Answer 6

alternative splicing of pre-mRNA

Question 7

what inhibits translation?

Answer 7

micro RNA & interfering RNA

Question 8

morphogenesis

Answer 8

the physical process that gives an organism its shape

Question 9

cytoplasmic determinants

Answer 9

-substances in the maternal egg that influence cells
-they influence pattern formation, or “body plan” for the organism

Question 10

induction

Answer 10

cell to cell signals that can cause a change in gene expression
