Question
In eukaryotes, transcription occurs in the nucleus. Chargaff's rules states that the amount of DNA base pairs (G:C and A:T) varies from species to species. Chargaff's rule states that G=C and that A=T. Gene expression includes the process of making an RNA transcript from DNA. Gene expression includes the processes of utilizing the transcript in the production of protein. Three types of RNA (mRNA, tRNA & IRNA) are required for translation. The genetic code is nearly universal (used and understood by all life forms on this planet). The primary structure of a protein is encoded by the DNA. The DNA code is considered unambiguous because a given codon can specifies one amino acid. More than one codon can specify the same amino acid.Explanation / Answer
19. T
DNA makes chromosomes which remain in the nucleus. Transcription occurs in the nucleus therefore.
20. F
Chargaff’s rule is applicable to all life forms, from bacteria to humans.
21. T
As G base pairs with C and A with T, G=C and T=A.
22. T
Gene expression is the process of utilizing the gene to make its final product – Protein. Transcription is ‘included’ in gene expression (as the statement says).
23. T
Gene expression is the process of utilizing the gene to make its final product – Protein. Translation is ‘included’ in gene expression (as the statement says).
24. T
mRNA encodes the protein sequence, tRNAs read the mRNA and rRNAs form the ribosome structure.
25. T
Yes. It is ‘nearly’ universal (as the statement says). There are exceptions though.
