EX1 Q3

Question 1

Non-Coding RNA (ncRNA)

Answer 1

a diverse class of RNA molecules that are transcribed from DNA but are not translated into proteins

Question 2

Transfer RNA (tRNA)

Answer 2

Acts as an adapter between the mRNA’s genetic code (codons) and the amino acids that are used to build a protein.

Each tRNA molecule carries a specific amino acid and recognizes a specific codon on the mRNA, ensuring that the correct amino acids are added to the growing protein chain during translation.

Question 3

Ribosomal RNA (rRNA)

Answer 3

Helps hold mRNA in place and catalyze the formation of peptide bonds between amino acids during protein synthesis.

Question 4

RNAi (RNA interference)

Answer 4

used in gene regulation and silencing

Question 5

MicroRNA (miRNA)

Answer 5

Basically, the miRNA stops the mRNA from being translated into protein.
It does this by binding to a complementary mRNA gene sequence with the help of a protein (AGO)

Question 6

Small Interfering RNA (siRNA)

Answer 6

-A double-stranded RNA molecule
-One of the strangs binds to the RISC complex
-The RISC complex then binds to mRNA with a complementary sequence to inhibit or destroy it
