Which aminoacid is determined by 4 genetic codes

Which of the following is true with reference to transformation in bacteria
i) Transfer of genetic material is mediated by F factor
ii) Uptake of DNA fragments from the surrounding environment and expression of that genetic information in recipient cell 
iii) Transformation experiments were the basis to propose chromosomal theory of inheritance
iv) Transformation was discovered by Griffith in Streptococcus pneumonia

The codons UUU and UUC codes for phenylalanine only. This feature of genetic code is called

A molecule that acts as a genetic material must fulfill the traits given, except

Escherichia coli in which both the strands are labelled with $$^{15}N$$ is transferred to $$^{14}N$$ medium and allowed to replicate for two generations. Find the number of hybrid DNA molecules in the second generation

Read the following statements carefully and choose the correct ones
a) In a transcription unit, the promoter located at the 5 end of coding strand
b) The single strand DNA having the polarity 5 3 is the template strand
c) RNA polymerase binds to the operator during transcription
