In this question A is Franis Crick, B is translation and C is transcription. It is unidirectional flow of information DNA to mRNA (transcription) and then decoding the information present in mRNA in the formation of polypeptide chain or protein (translation).

Correct Option: A

In this question A is Franis Crick, B is translation and C is transcription. It is unidirectional flow of information DNA to mRNA (transcription) and then decoding the information present in mRNA in the formation of polypeptide chain or protein (translation).

Transcription unit consists of promoter, structural gene & terminator.

Correct Option: A

Transcription unit consists of promoter, structural gene & terminator.

Removal of RNA polymerase III from nucleoplasm will affect the synthesis of tRNA while RNA polymerase I forms r-RNA and RNA polymerase II form m-RNA is Eukaryotes.

Correct Option: A

Removal of RNA polymerase III from nucleoplasm will affect the synthesis of tRNA while RNA polymerase I forms r-RNA and RNA polymerase II form m-RNA is Eukaryotes.

Remonal of introns by spliceosome in hnRNA and joining of exons by DNA liagse in a defined order during transcription is called splicing.

Correct Option: D

Remonal of introns by spliceosome in hnRNA and joining of exons by DNA liagse in a defined order during transcription is called splicing.

Genetic code is the relationship of amino acid sequence in a polypeptide and nucleotide/base sequence in mRNA/ antisense strand of DNA. It is universal, i.e., a codon specifies the same amino acid in all organisms, non-overlapping, i.e., adjacent codons are independent with no base being member of two codons, degeneracy, i.e., some amino acids are coded by more than one codon, hence the code is degenerate, unambiguous, i.e., one codon codes for only one amino acid.
