Answer:
Option (b).
Explanation:
Carrier proteins allow the movement of the particles inside and outside the cells. Three types of porter are uniport, symport and antiport. These porters transport molecules in the different directions.
The antiporters transport two molecules at a time. These two molecules are transported in the opposite directions at the same time. The one molecule will move inside the cell and the other molecule will move outside the cell.
Thus, the correct answer is option (c).
Most synapses in our body uses the acetyl choline neurotransmitter.

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.
Answer:
- The three roles of RNA in protein synthesis. Messenger RNA (mRNA) is translated into protein by the joint action of transfer RNA (tRNA) and the ribosome, which is composed of numerous proteins and two major ribosomal RNA (rRNA) molecules. ... Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes.
2. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.
Explanation:
The first one is for How do the three types of RNA work together to create proteins
And the second is for using the genetic information contained within DNA?
