Protein and nucleic Acid

Nucleic Acids are responsible for all of the following except

• Dictate amino acid sequence

• Transfer of genetic information

• Blue print of all the instructions for cell function

• Energy formation for organism

---------- subunits of nucleic acids are nucleotides

RNA is synthesized in the nucleus and exported via nuclear pore to

• Cytosol

• Mitochondria

• Nucleus

• Cytoplasm

--------- sugar is almost the same but lacks one

oxygen atom

--------------are large, ----------ring molecules found in both DNA and RNA

• Purines, single

• Pyrimidine Single

• Purines, Double

• Pyrimidine Double

The mode of DNA replication accepted widely is

• dispersive theory

• dispersive theory

• semi-conservative

• evolutionary theory

HOW MANY STOP CODONS ARE PRESENT IN NATURE FOR PROTEIN SYNTHESIS

• 2

• 1

• 3

• 64

---------- gave Chargaff’s Rules, proved that guanine and cytosine units, as well as adenine and thymine units, were the same in double-stranded DNA

DNA replication on leading strand occurs from

• 5'-3'

• 3' OH

• 3'-5'

• 5' PO4

The addition of a deoxyribonucleotideto the 3' end of a polynucleotide chain (the primer strand) is the fundamental reaction by which DNA is synthesized DONE BY -------
