Question

Francis Crick and Sydney Brenner studies with phage demonstrating that functional bacteriophage proteins are made in bacterial cells only when DNA bases were present in the correct multiples of three, supported the principle that ________________.


three codons in a row are required for DNA replication
bacteriophage possess a unique genetic code made up of three deoxyribonucleotides
amino acids are encoded by specific combinations of three deoxyribonucleotides in DNA
three bases arranged in the correct order are required to make three correct proteins
the redundancy of having three codons in a row ensures that DNA can be transcribed into mRNA

Explanation / Answer

Bacteriophage possess a unique genetic code made up of three deoxyribonucleotides
