Pairs of Unit Factors, or Genes

Mendel proposed that paired unit factors of heredity were transmitted faithfully from generation to generation by the dissociation and reassociation of paired factors during gametogenesis and fertilization, respectively. After he crossed peas with contrasting traits and found that the recessive trait resurfaced in the F2 generation, Mendel deduced that hereditary factors must be inherited as discrete units. This finding contradicted the belief at that time that parental traits were blended in the offspring.

A gene is made up of short sections of DNA that are contained on a chromosome within the nucleus of a cell. Genes control the development and function of all organs and all working systems in the body. A gene has a certain influence on how the cell works; the same gene in many different cells determines a certain physical or biochemical feature of the whole body (e.g., eye color or reproductive functions). All human cells hold approximately 21,000 different genes.

Genetics is the science of the way traits are passed from parent to offspring. For all forms of life, continuity of the species depends upon the genetic code being passed from parent to offspring. Evolution by natural selection is dependent on traits being heritable. Genetics is very important in human physiology because all attributes of the human body are affected by a person’s genetic code. It can be as simple as eye color, height, or hair color. Or it can be as complex as how well your liver processes toxins, whether you will be prone to heart disease or breast cancer, and whether you will be color

A neuromuscular junction is a junction between a_________ and a ___________. A neuromuscular junction is a junction between a___
garri49 [273]

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.

The mrna codon CUU could mutate to C___ and still code for leucine, which could be a neutral mutation. What is the blank?
Lelechka [254]
A codon is a sequence of three bases found on the messenger RNA (mRNA) molecule which is translated to produce an amino acid. Each amino acid is coded by one or more specific codons. If the codon is changed through a mutation, the amino acid produced may be different. However, in this case, the other codons that produce Leucine are:

UUA, UUG, CUU, CUC, CUA and CUG

So the code CUU could mutate to CUC, CUA or CUG and leucine would still be produced.
