The red lines represent dna. true the model shows the correct polarity between the orange and red strands. the 5' labels refer t

o the end of the strand with a nitrogenous base. the model correctly shows an arrowhead on the 3' ends of the strands. hydrogen bonds between the orange and red strands are not shown but are implied by the model. the 3' labels refer to the end of the strand with a phosphate group. the orange line represents rna.

This model of red and orange lines represents the process of transcription.

The 5' labels refer to the end of the strand with a nitrogenous base. false
The 5' label at the end of the DNA strand refers to the phosphate group of the last nucleotide of the strand.

The model correctly shows an arrowhead on the 3' ends of the strands. false
The arrowhead on the 3' ends of the DNA is incorrectly put there. This is because arrowheads are only used to show the direction of the formation of RNA.

The 3' labels refer to the end of the strand with a phosphate group. false
The 3' labels refer to the end of the strand with a hydroxyl group of the last nucleotide of the strand.

Hydrogen bonds between the red and orange strands are not shown but are implied by the model. true
The newly formed RNA molecule is bound to the template DNA with hydrogen bonds. Normally, models describing the transcription process need to show the presence of the hydrogen bonds.

The red lines represent DNA. true
The red lines represent the unwinded double-stranded DNA.

The orange lines represent RNA. true
The orange lines represent the RNA molecule formed based on the template strand of nucleotides

The model shows the correct polarity between the orange and red strands. false
The RNA polymerase builds the RNA molecule by creating a strand that grows from 5' to 3' (this is correctly shown at the model). However, the template strand of DNA is read by the DNA polymerase in the 3' to 5' direction. Therefore, the model needs to show that the RNA molecule is bound to the other strand of DNA, the one with the 3'-5' direction.
