1

_____ do not encode ________

NCRNAS polypeptides

2

How do NCRNAS bind to DNA and RNA

complementary base pairing

3

how do NCRNAS bind to proteins/small molecules

scaffold protein = binding site for molecules

4

abbreviation protein functions?

DRAGBS

5

kindaps NCRNAS

decoy

6

catalyzes functions

ribosome

7

Alter function/ stability changes

ability to act as enzyme
bind to other molecules
Stability

8

are telomeres in eukaryotic or prokaryotic

eukaryotic

9

why is there an overhang?

ends of chromosomes can’t be replicated fully

10

constraints for replications

Needs to stetch
5 to 3

11

why can’t telomeres replicate?

there isn’t enough room in chromosome

12

what fixes overhang problem

telomerase

13

telomerase is an

A. Enzyme
B. Protein
C. NCRNA

enzyme

14

what does telomerase considt of?

protein part
NCRNA - TERC

15

Steps of telomere lengething

Binding
Polymerization
Translocation

Banning polygamy train

16

what happens in binding? (Telomerase)

TERC is a guide
Telomerase finds end of DNA

17

what happens in polymerization (telomerase)

TERC is template!
rna —> DNA

18

what happens in translocation?

moved to new end :)

19

What was the goal of the fire mello

how does ncrna silence mRNAS

20

when injected with ____ rna the _____ dissapeares

double, mex 3

21

Does RNAi interference happen in eukaryotes or prokaryotes?

Eukaryotes

22

two NRNAS that cause RAi

miRNAS (micro)
SIRNAS

23

micrornas are _______ and
______ to mRNAS

endogenous
complementary

24

SiRNAS are ______ and ______ to mrNA and prevent __________

exogeneous, complementary, viral infections

25

CDBGMISI

CANNABIS DISPENSARY BRINGS GOOD MONEY IN SOUTH INDIANA

chop
degrade 1 strand
bind
guide to mRNA

MiRNA - inhibit
SiRNa - degrade

26

SRPRNA acts as _____ and _______

scaffold, alters structure

27

what happens when SRP interacts

Pauses translation

28

what happens when the translation is paused in SRP

receptor binds

29

What happens when recepotor binds SRP

GTP is hydrolyzed
SRP is released, can resume translation :)

30

CRISPR CAS type 11 defends against

bacteriophages and trabsposons
