3. are removed by DNA polymerase I.
A primer is a short nucleic acid sequence that provides a starting point for DNA synthesis which has to be removed after DNA synthesis by DNA polymerase
4. it is not RNA as it contains thymine and RNA contains Uracil.
In double-stranded DNA
A + T = G + C
30 + 35 # 15 + 35
and as A+T is not equal to G+C it is not double-stranded DNA. Thu it is single-stranded DNA.
