Concept explainers
(a)
Interpretation: The base sequence of the hnRNA strand synthesized from the DNA template strand has to be stated.
Concept introduction: hnRNA can be formed by the transcription of DNA. Transcription process occurs in nucleus. DNA strand contains a segment called “gene” which contains the base sequences for production of hnRNA.
(b)
Interpretation: The base sequence of the mRNA strand synthesized from the hnRNA strand has to be stated.
Concept introduction: hnRNA can be formed by the transcription of DNA. Transcription process occurs in nucleus. DNA strand contains a segment called “gene” which contains the base sequences for production of hnRNA.
(c)
Interpretation: Codons present in the mRNA strand produced from the DNA template strand has to be mentioned.
Concept introduction: hnRNA can be formed by the transcription of DNA. Transcription process occurs in nucleus. DNA strand contains a segment called “gene” which contains the base sequences for production of hnRNA.
(d)
Interpretation: The tRNA molecule anticodons needed to interact with the codons present in the mRNA strand produced from the DNA template strand has to be stated.
