Answer:
(A). Result in different amino acids to be read due to frame shifts
Explanation:
Insertion or deletion mutations (or Indel mutations) can be defined as mutations in DNA due to insertion (addition) or deletion of nucleotide bases in DNA.
These mutations lead to change in reading frames (sequence of codons), which leads to formation of protein having completely different amino acid sequence. Hence, these mutations are also cause frameshift mutations.
This is due due to triplet nature of genetic codes as insertion or deletion of one or more bases (but not three) would change change in codon sequence and mutated sequence can form a non-functional or truncated protein.
Thus, the correct answer is option (A).
Answer:
Jane: Aa
Matthew: aa
Explanation:
Jane is a heterozygous woman, which means that she is dominant for this genetic trait while Matthew is homozygous that did not inherit the achondroplastic dwarfism trait from his parents, that is why he is alive.
If we draw a Punnett square, we can see that some of their children will inherit the trait while others will not.
<u> ║ a ║ a</u>
<u>A ║ Aa ║Aa</u>
a ║ aa ║ aa
This is referred to as: spontaneous recovery
Spontaneous recovery is a theory of learning and memory which involves unexpected and recurrence of a conditioned response after a period of reduced response or delay. Spontaneous recovery is associated with classical conditioning and operant conditioning. Extinction will happen quickly after a spontaneous recovery, if the conditioned and unconditioned stimulus is not connected.
Given:
Allele for green pod colour = Gg (Heterozygous)
Allele for Yellow pod colour = gg (Homozygous)
Explanation:
Parents: Gg x gg
When this two parent are crossed, it leads to the following F1 generation (off springs):
<em>• Gg (green colour pod)
</em>
<em>• Gg (Green colour pod)
</em>
<em>• gg (Yellow colour pod)
</em>
<em>• gg (Yellow colour pod)
</em>
Form the produced offspring it can be inferred that the allele combination for green colour pod is Gg. Among the four off springs obtained 2/4 are green colour pod and 2/4 are yellow colour pod.
I believe it's Preganglionic Neurons
because in parasympathetic the pre-ganglionic neurons begin in the brain stem, and secretes Aceytolcholine as a neurotransmitter. ;)
I'm taking A&P2 this spring so I know haha
