In a DNA molecule, the end with the 3' designation has a free hydroxyl group on the third carbon of the sugar molecule, while the end with the 5' designation has a free phosphate group on the fifth carbon of the sugar molecule. This can be determined by examining the structure of the DNA molecule.
The 5' end of a DNA strand refers to one end of the molecule where a phosphate group is attached to the 5' carbon of the sugar molecule in the DNA backbone. This end is important for determining the directionality of the DNA strand. The 5' end impacts the structure and function of the DNA molecule by influencing how enzymes read and replicate the DNA sequence. It also plays a role in the process of transcription, where genetic information is used to create RNA molecules.
False: DNA replication starts at origins of replication which can be anywhere on the DNA molecule. Replication is taking place at multiple origins at the same time.
After DNA replication, each new molecule has one strand of the original DNA molecule and the other strand is composed of new nucleic acids. This is due to the semi-conservative replication of DNA.
Each chromosome is originally made of one DNA molecule.
The DNA molecule contains the genetic instructions that determine the traits and functions of an organism. It serves as a blueprint for the synthesis of proteins and plays a crucial role in cell growth, development, and reproduction. The DNA molecule also carries hereditary information that is passed down from one generation to the next.

The DNA molecule is anti-parallel. This is because the two strands are the opposite of one another, such that if one strand has the base sequence ATC, the opposite strand would have the base sequence TAG.

One can determine whether a nucleotide is DNA or RNA by looking at the sugar molecule it contains. DNA nucleotides have deoxyribose sugar, while RNA nucleotides have ribose sugar. This difference in sugar molecules helps distinguish between the two types of nucleotides.
There is one double helix DNA molecule per chromosome.
A molecule is polar if it has an uneven distribution of electrons, causing one end to be slightly positive and the other end to be slightly negative. This can be determined by looking at the molecule's shape and the electronegativity of its atoms. If there is a significant difference in electronegativity between the atoms in the molecule, it is likely to be polar.
DNA actually has 3 forms. A-DNA, B-DNA, and Z-DNA. B-DNA is the kind you are most familiar with and present in most organisms. A-DNA can be found in dehydrated samples while Z-DNA is rare and mostly synthesized in the lab.
we started with a single strand DNA molecule.
Each DNA molecule formed is half new, with one strand coming from the original DNA molecule and the other newly synthesized during replication. This process ensures that each new DNA molecule contains one original strand to serve as a template for accurate replication.
