what are the two categories that tRNA are divided into?

Mitochondrial and cytoplasmic

1 of 12

What is the main role of tRNA and what are the other roles?

MAIN: protein translation

SUB: adaptive protein synthesis and regulatory networks

2 of 12

what is adaptive protein synthesis

changes the rate of protein synthesis based on modifications of the anticodon loop

3 of 12

are tRNA's coding or non coding?

tRNAs are part of the non coding structural RNA's

4 of 12

What are rRNA's used for ?

ribosome biogenesis and translation

5 of 12

what is the function of an rRNA in a ribosome?

acts as a ribozyme. Their structure is involved in the catalysis of going from substrate to product.

6 of 12

what are the two regulatory RNA's

long non-coding RNA's (lnsRNAs) and small non-coding RNA's (ncRNA's)

7 of 12

what are the functions of long non-coding RNA's ?

the functions are not really understood lincRNA (long intergenic ncRNA) epigenetic gene regulation.
cRNA (chromosomal RNA) binds chromatin to modulate expression
controlling other ncRNA's e.g microRNA sponges

8 of 12

what are the functions of small non-coding RNA's?

mainly regulatory
bind to target mRNA's leading to degradation or translational inhibition

9 of 12

what are the properties of long non-coding RNA's?

longer than 200 nucleotides
most contain poly-A-tails

10 of 12

what are the properties of small non-coding RNA's?

smaller than 200 nt
most contain poly-a-tails
post transcriptional processing to 'functional' forms

11 of 12

what are the two major classes of transposable elements

class I retrotransposons
class II DNA Transposons
