Question

23) What is the complementary strand for a single DNA strand with the sequence TCGA E) AGCT A) TGCA B) TCGA C) GATC D) CTAC 24) A codon is A) a sequence of three nucleotides in RNA that codes for a specific amino acid or for chain termination. B) a sequence of three amino acids that translates to a specific nucleotide in RNA. C) all the segments of DNA needed to direct the production of a specific protein. D) the collection of DNA that stores all the genetic information for an individual organism. E) a complex of proteins and DNA which is associated with cell division. 25) Which molecule shown is a D-isomer? A) B) C) D) CHO CHO HO-C-H HO-C-H H-C-OH HO-C-H HC OH HO-C-H HO-C-H HO-C-H HO-C- H H-C-OH HO-C-H CH2OH HO-C-H HO-C-H CH20H CH20H

Explanation / Answer

23.complimentary base pairs : A and T

     .complimentary base pairs : G and C

      Therefore for TCGA the complimentary strand for single DNA strand is AGCT (option E)

24 A Codon is a sequence of three nucleotides in RNA that codes for a specifc amino acid or for chain

    termination (option A)

25 D-isomer of glucose is option C
