The addition of an extra nucleotide to a DNA sequence produces a mutation that is called insertion. An insertion mutation can be in various sizes, from one nucleotide base pair to a section of one chromosome inserted into another. When one or more nucleotides are inserted into the genome, the processes of translation and transcription could be disrupted, resulting in altered protein synthesis.
Over the past four decades, researchers have identified many types of oncogenes, including growth factor receptors, transcription factors, and intracellular signaling proteins.
<h3>What are oncogenes?</h3>
These are specific genes in an organism that can cause the formation of cancer. These genes are prone to defects that when activate, signal for a cell to become a tumor. The genes listed in the question are some examples of the types of cells that can be oncogenes.
Therefore, we can confirm that over the past four decades, researchers have identified many types of oncogenes, including growth factor receptors, transcription factors, and intracellular signaling proteins.

Answer:
A - 1/4
B - 1/2
C- 1/8
Explanation:
The complete question is
Diane has type A blood and Darryl has type B. They have a son Duane with type A blood and a daughter, Dora, with type B blood. If they have another child, what are the chances that it
A. Will have type AB blood?
B. Will be a girl?
C. Will be a boy with type O blood?
A.
Let the genotype of Diane be AO
Daryl can have genotype BO
AO * BO
AB, AO, BO, OO
Probability of having AB blood group is 1/4
B.
1/2
C
1/2 * 1/4 = 1/8
Answer;
-Neurotransmitters.
One of the first key terms she memorizes is neurotransmitters because these are the chemicals via which neurons communicate with each other.
Explanation;
-Neurons communicate with each other via electrical events called 'action potentials' and chemical neurotransmitters. At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter.
-Neurons are connected to each other through synapses, sites where signals are transmitted in the form of chemical messengers.
