Question 8

It acts as a unified system, performing all the functions required for RNA synthesis

Answer 8

RNA POLYMERASE

Question 9

Serves as our blueprint where we encode the bases of our RNA

Answer 9

● TEMPLATE STRAND

Question 10

also known as the sense strand or non-template strand, is one of the two strands of DNA that serves as a template for mRNA synthesis during transcription.

Answer 10

CODING STRANDS

Question 11

t delivers the bases needed to pair with the RNA, essentially carrying the letters for RNA synthesis.

Answer 11

NTPs - Nitrogen triphosphate

Question 12

This portion is a combination half
in half, half dna and half rna
→ This is also temporary.

Answer 12

● RNA-DNA HYBRID REGION

Question 13

signifies the starting point of
initiation

Answer 13

TATA

Question 14

→ This is the site of the main event, where everything happens.

Answer 14

ELONGATION

Question 15

This region serves as the starting point for transcription.

Answer 15

initiation

Question 16

The promoter region consists of four bases: Thymine, Adenine, Thymine, and Adenine.

Answer 16

initiation

Question 17

→ Matches the mRNA sequence

Answer 17

the coding strand

Question 18

→ Initiates transcription

Answer 18

RNA Polymerase

Question 19

This sequence emits signals
indicating the end or termination of
the process.

Answer 19

TERMINATION

Question 20

REQUIREMENTS BEFORE LEAVING THE NUCLEUS

Answer 20

Processing, quality check, packaging

Question 21

involves removing unnecessary bases because not all of the codes are essential for maturation

Answer 21

splicing

Question 22

Are required to make proteins

Answer 22

mRNA

Question 23

This complex assists in removing unnecessary elements.

Answer 23

○ Spliceosome

Question 24

are catalytic RNA molecules that function as enzymes and can splice RNA

Answer 24

Ribozymes

Question 25

This process involves double-checking and proofreading errors, correcting any discrepancies that may arise.

Answer 25

EDITING

Question 26

→ Signals the end of mRNA
→ Exports mRNA out of the nucleus
→ Protects mRNA from enzymes that
might break it down

Answer 26

POLYADENYLATION

Question 27

→ Single Guanine
→ Consist Guanine

Answer 27

5’cap

Question 28

→ “Poly A tail”
→ Around 250 Adenines

Answer 28

○ 3’ tail

Question 29

this serves as the primary template for synthesizing proteins by ribosomes. It is the central player, holding the blueprint for protein synthesis.

Answer 29

Messenger RNA

Question 30

transfers specific amino acids to growing polypeptide chains at the ribosomal site of protein synthesis during translation

Answer 30

➔ Non-coding RNA
