A short essay on the website describing the information provided and the purpose of this information about the genome is given Genomes are product of DNA, a very massive molecule that looks as if a lengthy, twisted ladder.
<h3>What does genome appearance like?</h3>
If all of the DNA from a single human cell turned into stretched-out end-to-end, it'd make a six-foot-lengthy strand created from a six billion letter code. It’s difficult to assume how that a good deal DNA may be packed right into a cell nucleus, that's so small it could simplest be visible with a specialized microscope.
DNA is examined like a code. This code is made from 4 styles of chemical constructing blocks, adenine, thymine, cytosine, and guanine, abbreviated with the letters A, T, C, and G. The order of the letters on this code permits DNA to characteristic in exceptional ways. The code modifications barely from individual to individual to assist make you who you are.

If an experiment is not verifiable, the person doing the experiment would never be able to get the answer to their hypothesis. Hypotheses need to be testable.
Hope that clarified things.
I don’t really have an answer but I have an explanation
Explanation: In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. These pairs of genes then determine certain physical features or traits.
Explanation:
Synapses are junctions at axon terminals where they connect to dendrites of other neurons at these junctions chemical reactions occur in order to facilitate the passage of information as chemical signals. There are several neuron types which include sensory motor and into neurons which bridge the two.
1. At neuromuscular junctions, electrical signals are transmitted:
- The action potential travels along the membrane until the synapse where it’s electrical depolarization leads to the opening of channels allowing only sodium ions to enter
- these flow through a presynaptic membrane until the concentration is built up, activating ion sensitive proteins attached to vesicles containing neurotransmitters like acetylcholine
- this leads to changes in the proteins leading to the fusion with the membrane of the presynaptic cell, so vesicles are open and neurotransmitter is released. The neurotransmitter diffuses across to chemical receptors on the presynaptic cell where they bind temporarily. This increases the permeability of the sarcolema to Na+;a new action potential is generated
2. Contraction of the sarcomere occurs via several steps.
- This action potential in the muscle, travels along T-tubules, and Ca+ ions are released by the sarcoplasmic reticulum into the sarcoplasm
- Ca and troponin combine, pulling myosin filaments, exposing the actin filament's myosin binding sites
- cross-bridge formation occurs, leading to the sliding of filaments.
- ATP drives cross-bridge cycling while mysosin pulls on actin strands
- muscle fibers shorten and contract
- later ACH is degraded in the synapse. Na ions are not released, and the action potential is not transmitted.
- the Ca channels on the SR close, while Ca is reabsorbed stopping Ca-troponin binding, closing myosin binding sites on actin and leading to cross bridge separation. The muscle fiber relaxes in their resting states.
