Which statement about the incorporation of a nucleotide into DNA is true?

A. Before incorporation into DNA, nucleotides are in their tri-phosphate form.

B. The nitrogenous base in the nucleotide determines the orientation of the phosphate residues.

C. The nucleotide that has been incorporated into a DNA molecule has three phosphate groups.

D. The sugar (ribose or deoxyribose) determines the number of phosphate residues.

Expert Solution

Incorporation of nucleotide means addition of nucleotide in the DNA molecule. A nucleotide consists of N2 base, deox-ribose sugar and phosphate group. Whent e nucleotides are incorporated in to DNA, they have a single phosphate group.Ribose or de-oxy ribose has no effect on number of phosphate group.Orientation of the phosphate group is determined by the sugar molecule. Before the incorporation of nucleotide in to DNA, they are in their tri-phosphate form. With i the nucleoplasm there are nucleotides present in their tri-phosphate form. When they get incorporated in to DNA, they loose two of their phosphate groups.

A is the right option.

Which statement about DNA replication in eukaryotes is true? Group of answer choices Nucleotides are added...

Which statement about DNA replication in eukaryotes is true? Group of answer choices Nucleotides are added from beginning to end of one strand, from 5' to 3', and then to the other strand. Errors that occur during DNA replication are repaired by DNA polymerase. DNA helicase adds nucleotides with complementary bases to the strand of DNA that is being synthesized. DNA replication only occurs in somatic cells. Nucleotides are added to the 5' end of the growing DNA strand.

13) Which nucleotide monomer is REPLACED by the nucleotide URACIL (U) when a gene (DNA) is converted to an mRNA during the process of transcription? A) Adenine B) Guanine C) Cytosine D) Thymine 14) Different RNA molecules have diverse roles in cell biology; for example- mRNAs are the substrates for protein synthesis, which is performed by a large enzyme complex called the ribosome- a cellular machine composed of proteins and: A) siRNA B) rRNA C) tRNA D) All of these...

Which of the following is/are true about DNA replication? A) Primase is needed to initiate DNA replication on both the leading strand and the lagging strand. B) The sliding clamp is loaded once on each DNA strand, where it remains associated until replication is complete. C) Telomerase carries its own DNA molecule to use as a primer at the end of the lagging strand. D) Primase requires a proofreading function that ensures there are no errors in the RNA primers...
