MCQ on DNA Translation
After a mature mRNA leaves the nucleus of a cell, it heads for a __ in the cell’s cytoplasm where the code it contains can be translated to produce a protein
centrioles
Ribosome
mitochondria
Golgi apparatus
Ribosome
Each codon specifies one _ in the polypeptide chain of a protein.
Sugar molecule
Fatty acid
amino acid
None of these
amino acid
Each codon specifies one amino acid in the polypeptide chain of a _
protein
Carbohydrate
Vitamin

DNA translation is a crucial process in molecular biology where the genetic information encoded in messenger RNA (mRNA) is decoded to produce a specific sequence of amino acids, forming a polypeptide chain. This process occurs in the ribosomes, utilizing transfer RNA (tRNA) molecules to match codons on the mRNA with corresponding amino acids.
Number of possible codons is?
12
144
64
89
64
_ is called the start codon because translation begins here
AUG
UAA
UAG
UGA
AUG
AUG represents the amino acid _
Leucine
Lysine
methionine
phenylalanine
methionine
methionine is the _ amino acid added to the polypeptide chain in RNA translation
second
first
third
fourth
first
The codons UAA, UAG, and UGA are called _ codons
Start
middle
stop
None of these
stop
Stop codons include _
UAA
UAG
UGA
All of these
All of these
_ represent arginine
CGU
CGC
CGA
CGG
All of these
All of these
In order for your cells to decode mRNA, they need the help of an important worker i.e __
Ribosomal RNA

transfer RNA
Both of these
None of these
transfer RNA
Each tRNA has a special group of three nucleotides, called a _, that pairs up with the codons in mRNA
anticodon
Exons
introns
None of these
anticodon
