A DNA strand was sequenced using the Sanger method
(https://www.youtube.com/watch?v=KTstRrDTmWI). The reaction
tube contained the DNA strand, fluorescently labelled
dideoxynucleotide triphosphates (ddATP – yellow, ddGTP – green,
ddCTP – blue, ddTTP - red), deoxynucleotide triphosphates, DNA
polymerase, or its Klenow fragment. Synthesis of DNA is allowed to
proceed, and the results are shown on the right:

- Which of the following is true of primers that are used in DNA replication? They are made out of ribonucleotides with a possibility of having a thymidine base. They are made out of ribonucleotides with a possibility of having a uracil base. They are made out of deoxyribonucleotides with a possibility of having a thymine base. They must be made up of proteins.arrow_forwardDNA is made of two strands that are antiparallel. If one strand runs from 3’ to 5’ direction the other one will go from 5’ to 3’ direction. During replication or transcription, whatever the process is, it will always follow the 5’ to 3’ direction using the 3’ to 5’ directed strand as the template strand. Therefore, if following is the DNA sequence 5’-CCG ATC GCA CAA-3’ Using this sequence as template after transcription no protein can be translated. Why?
