How do components of a DNA molecule influence its physical properties? (3 points) Deoxyribose and phosphate, linked by phosphodiester bonds, form repeating units to make up the backbone of DNA. Deoxyribose molecules, nitrogenous bases, and phosphate side chains are linked by glycosidic bonds to give DNA its helical shape. Nitrogenous bases and phosphate groups are linked by peptide bonds and then folded to give DNA its helical shape. Nitrogenous bases have a phosphate bound to its 3' end and a deoxyribose bound to its 5' end to form the backbone of DNA.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added

the  different  of  these  two  are  that  they  differently  handle  their  team.

an  expressive  leader  focuses  on  the  task  at  hand  and  make  sures  that  their  goal  is  achieved.  they  accurately  finish  the  task.  an  instrumental  leader  on  the  other  hand  works  on  the  unity  of  the  group,  they  care  more  about  their  employees.  all  the  while  creating  a  good  environment.
