RNA

Question 1

mRNA

Answer 1

Messenger RNA

Question 2

tRNA

Answer 2

Adaptor between mRNA and amino acids

Question 3

Telomerase RNA

Answer 3

Template for telomerase enzyme
Role in apoptosis

Question 4

snRNA

Answer 4

Small nuclear
Composes spliceosomes

Question 5

snoRNA

Answer 5

Small nucleolar
Process and chemically modify rRNA Alternative splicing
If over-expressed⇒cancer

Question 6

lncRNA

Answer 6

Long noncoding RNA
Modulate histone/DNA modification
Ex. Methylation (supress) and acetylation (promote) of histones
Regulation and expression, including X-chromosome inactivation.

Question 7

miRNA

Answer 7

Micro,
Regulates gene expression by blocking translation

Question 8

siRNA

Answer 8

Small interfering,
Turn off gene expression by degrading mRNA
Uses RNAi ır PTGS (post transcriptional gene silencing

Question 9

piRNA

Answer 9

Piwi interacting,
spermatogenesis.
Combination of piRNA and Piwi proteins→Silencing of transposons.
Transposons=Important for evolution

Question 10

Xist RNA

Answer 10

X-inactive specific transcript, long noncoding, gene regulation of X chromosomes in females
