Answer:
Single nucleotide deletion
Explanation:
Original DNA sequence:
A T A C G G T A
T A T G C C A T
Mutated DNA sequence:
A T C G G T A G
T A G C C A T C
In the mutated sequence, there is a nucleotide missing. It goes from ATACGGTA to ATCGGTAG. The A nucleotide is gone. This represents a single base pair deletion.
Even though it is only one base, this changes the way the entire sequence is interpreted. The DNA transcribed into an mRNA and then translated into a protein by reading triplet codons which correspond to specific amino acids.
So while the initial sequence would be read as:
ATA, CGG, TA...
The new sequence would be read as:
ATC, GGT, AG...
So the sequence of the protein is completely altered.
The question is stated incorrectly. The correct question is as follows;
The site of intercellular communication between a neuron and another cell is the.
Answer:
Synapse.
Explanation:
Neurons have dendrites, cell body and axons. Millions of neurons are present in the nervous system. Different types of neuron are sensory neuron, motor neuron and interneuron.
Synapse may be defined as the gap between the two consecutive neurons. The junction between the two neurons that helps in the intercellular communication. The neurotransmitters are diffused directly and transmit information through these synapse.
Thus, the correct answer is synapse.
Answer:
In some ways, monotremes are very primitive for mammals because, like reptiles and birds, they lay eggs rather than having live birth. In a number of other respects, monotremes are rather derived, having highly modified snouts or beaks, and modern adult monotremes have no teeth.
Answer:
D it has a nucleus
Explanation:
It has a nucleus because it is an eukaryotic organism.
