Answer:
She left Ligase enzyme out of the mixture.
Explanation:
DNA replication is the process of formation of new molecules of DNA from the existing one. This process occurs in semiconservative way i.e each new strand consist of one newly synthesised strand and one old parent strand that act as template for the formation of new strand. replication on one strand occurs continuously from 5 prime to 3 prime but on other strands it occurs discontinuously from 5 prime to 3 prime because DNA polymerase moves only in one direction from 5 prime to 3 prime. Hence in discontinuous strands gaps remained. These gaps are filled by Ligase enzyme.
Requirements for DNA replication:
DNA replications needs
Primers
DNA Polymerase enzyme
DNA helicase enzyme
Single nucleotide binding protein
dNTPs
and Ligase enzyme.
Correct choice:
She left Ligase enzyme out of the mixture.
I believe another term for Natural Selection, based off of the answers provided, I would say C, Survival of the Fittest.
Phylogenetic trees show the evolutionary pathways and connections among organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms.
The independent variable controls the dependent variables.
Answer:
myofibril bulbous end of axon and skeletal muscles fibres.
Explanation:o
It represents the chemical synapse of the axon bulbous ends of the motor neuron ( motor end plate) and the skeletal Muscle fibres.
The influx of calcium ions into the bulbous ends leads to the fusion and empty of the vesicles containing neurotransmitters into the synaptic cleft.
The Neurotransmitters binds to the receptors on the muscles membrane to allow the transmission of action potential ( PSIP or PSEP)across the synaptic gap to the muscles fibers to initiate their contraction or relaxation.
