They have phosphate groups in the rings

A ribonucleotide triphosphate used in RNA synthesis has an OH group on this carbon in the sugar portion of the nucleotide:      2′

AAATTT

This is a transversion mutation

After making a peptide bond, the ribosome:

What kind of mutation is caused by intercalating agents such as proflavin?

Which of the following statements about nucleotides are true and which are false?    For both DNA and RNA, the backbones are sugar-phosphate chains

Below is a sequence of 100 base pairs from the ADE2 gene of yeast, and six 8 base oligonucleotide primers.  You wish to amplify portions of the ADE2 gene using PCR.  Which pairs of primers (oligos) will give you a PCR product if you use the given ADE2 genomic DNA as a template? how long will the product be?        Write how long will the PCR product be from each primer pair listed below (the answer is number only!). If the listed primer pair results in no PCR product, write 0. Primer pair 1+2 will give PCR product length: [1] Primer pair 1+3 will give PCR product length: [2] Primer pair 1+4 will give PCR product length: [3] Primer pair 1+5 will give PCR product length: [4] Primer pair 1+6 will give PCR product length: [5] Primer pair 2+3 will give PCR product length: [6] Primer pair 2+4 will give PCR product length: [7] Primer pair 2+6 will give PCR product length: [8] Primer pair 4+5 will give PCR product length: [9] Primer pair 3+4 will give PCR product length: [10] Primer pair 3+5 will give PCR product length: [11] Primer pair 3+6 will give PCR product length: [12]
