Explanation / Answer
The monomers that are chemically linked together to form nucleic acids are called nucleotides. They are monomers for nucleic acids like DNA, RNA. Nucleotides consist of sugar, base and a phophate group. Answer is c.
Phosphate groups in DNA connect the 3' and 5' positions of neighboring sugar units. In DNA, a covalent bond is formed between 5' phosphate group of one nucleotide and 3' -OH group of another nucleotide. Answer is a.
Phosphate and sugar units comprise a nucleic acid backbone. Nucleic acid consists of sugar, base and phosphate group. Answer is c.
A complementary strand (written in the 5'-3' order) for the DNA segment AGC is GCT. Answer is a.
mRNA is formed during transcription. Answer is d.
