Answer 1

8. Glycolysis is both aerobic and aerobic but it is a catabolic process. Where glucose is broken. So, answer is B. 9. Two ATP per cycle of glycolysis. It does not use ATP and is not anabolic and does not produce CO2. Answer is D. 10. It is an elimination reaction as double bond is formed after loss of H20. Answer is A. 11. Nucleotide backbones are held together by phosphodiester bonds among the 3' end of one to the 5' end of the other. Peptide and ionic bond is among protein and hydrogen bond is among the strands. Answer is A. 12. Hydrogen bonds between base pairs hold the DNA. Hydrogen bonds between adenine and thymine & guanine and cytosine. Answer is D. 13. Replication process produce daughter DNA which is identical and complimentary to parent. So, answer is A. 14. Translation is the process of protein formation from RNA. Transcription is RNA synthesis while replication is DNA synthesis and catabolism is a process of breaking of complex systems of molecules. Answer is C. 15. In transcription double stranded DNA opens and mRNA forms which is complimentary in base pairs to the parent DNA strand. Thymine here is replaced by uracil and hydrogen bond to adenine. Answer is B. 16. Adenine-thymine is found in DNA. Adenine-uracil is in RNA. Answer is D. 17. Codon is on mRNA and anticodon on tRNA. Answer is B.
