Question
Complete the paragraph using proper words:
(Cytoplasm, nucleus, double codon, triplet codon, 20, 18, translation, transportation, transcription, mutation, tRNA, mRNA)
The mRNA formed in nucleus comes in ______. It brings in the coded message from DNA. The message contains the codes for amino acids. The code for each amino acid consists of three nucleotides. It is called '______'. Dr. Har Govind Khorana, a scientist of Indian origin has made an important contribution in discovery of triplet codons for ______ amino acids. For this work, he has been awarded with the Nobel Prize in 1968, along with two other scientists. Each mRNA is made up of thousands of triplet codons. As per the message on mRNA, amino acids are supplied by the ______. For this purpose, tRNA has 'anticodon' having complementary sequence to the codon on mRNA. This is called as '______'. The amino acids brought in by tRNA are bonded together by peptide bonds with the help of rRNA. During this process, the ribosome keeps on moving from one end of mRNA to the other end by the distance of one triplet codon. This is called as '______'. Such many chains come together to form complex proteins. These proteins control various functions in the body of living organisms and their appearance too.
Solution
The mRNA formed in nucleus comes in cytoplasm. It brings in the coded message from DNA. The message contains the codes for amino acids. The code for each amino acid consists of three nucleotides. It is called 'triplet codon'. Dr. Har Govind Khorana, a scientist of Indian origin has made an important contribution in discovery of triplet codons for 20 amino acids. For this work, he has been awarded with the Nobel Prize in 1968, along with two other scientists. Each mRNA is made up of thousands of triplet codons. As per the message on mRNA, amino acids are supplied by the tRNA. For this purpose, tRNA has 'anticodon' having complementary sequence to the codon on mRNA. This is called as 'translation'. The amino acids brought in by tRNA are bonded together by peptide bonds with the help of rRNA. During this process, the ribosome keeps on moving from one end of mRNA to the other end by the distance of one triplet codon. This is called as 'translocation'. Such many chains come together to form complex proteins. These proteins control various functions in the body of living organisms and their appearance too.
