Nucleic acids store hereditary information. Think about DNA! DNA stands for dioxiriboNUCLEIC ACID. Your DNA determines everything about you’
Answer:
Explanation:
One of the functions of the muscle is the storage of amino acids which can be used for energy production when demands are high or for protein synthesis. But during muscle atrophy, this function becomes reduced which could lead to the particularly muscle been unable to stretch or contract due to weakness, it could also lead to the imbalance between protein synthesis and degradation.
A mutation that involves one or a few nucleotides is called
a) mutagen
b) inversion
c) point mutation
d) translocation
Answer:
c) point mutation
Explanation:
When only one or a few nucleotides of a gene are changed by mutation, this is called a point mutation. A point mutation can add one additional nucleotide to the wild type gene or may delete or substitute a nucleotide from it. For example, if a wild type gene sequence is "ATATATATA", then the addition of "C" at the position 4 will change it into "ATACTATATA". This addition of new nucleotide is called point mutation since only one nucleotide is added to the gene. Point mutations can cause serious genetic disorders such as sickle cell anemia.
Answer:
Efferent/motor neuron
Explanation:
Efferent/ motor neuron synapse with an effector because efferent neuron is a nerve cell such as motor neuron that transmit electrical impulses o r information from the centre nervous system to the effector which then cause or lead to physiological changes or response to the body . The contain majorly of motor neurons or nerve fiber that send signals from the central nervous system(brain /spinal cord) to the effector neuron for changes that occur physically.
