1

Elongation

________ is the process of polypeptide formation and is the second step on translation.

New cards
2

ribosomal subunits

The ________ dissociate and are returned to the cytoplasm.

New cards
3

Translation

________ occurs in three steps: initiation, elongation, and termination.

New cards
4

ribosome

The ________ transcribes the mRNA molecule until it finds a termination codon on the RNA. They are made up of ribosomal RNA and various proteins and has both a small subunit and a large subunit.

New cards
5

Termination

________ is the last step of translation and ends the process of protein synthesis.

New cards
6

MRNA

________ and tRNA unite in order to make proteins.

New cards
7

rRNA

________ is produced in the nucleus.

New cards
8

Initiation

________ occurs when all the products of translation are brought together and is the first step of translation.

New cards
9

Initiator RNA

________ is usually a form of methionine.

New cards
10

ribosomal units

The products that come from translation are ________, mRNA, and initiator RNA.

New cards
11

Multiple ribosomes

________ can attach to one mRNA simultaneously.

New cards
12

ribosome

The ________ confirms that its anticodon matches the codon on the mRNA.

New cards
13

Translation occurs in three steps

initiation, elongation, and termination

New cards
14

large subunit

"...composed of two RNA strands, a long orange strand and one yellow strand."

New cards
15

small subunit

“...is in charge of information flow during protein synthesis.”

New cards
16

methionine

"...is an amino acid found in many proteins including the proteins in food and those found in the tissues and organs of your body."

New cards
17

stop codon

"A stop codon is a genetic code that signals the end of protein manufacturing inside the cell..."

New cards
18

termination codon

A __________________ is a "trinucleotide sequence (UAA, UGA, UAG) that specifies the end of translation or transcription."

New cards
19

polypeptide

A ___________ is "a molecular chain of amino acids."

New cards
20

anticodons

" _____________ are a sequence of nucleotides that are complimentary to codons. They are found in tRNA's and allow the tRNA's to bring the correct amino acid in line with an mRNA during protein production."
