What
does a gene do?
Genes
tell your body how to make all its proteins. Each new cell in the growing
embryo receives a full set of genes. But not every cell needs to make every
protein and cells make some proteins only at certain times. Some genes are
instructions for proteins that regulate the activity of other genes.
Are
genes made of DNA?
Genes
are made of a chemical called DNA, which is short for 'deoxyribonucleic acid'.
The DNA molecule is a double helix: that is, two long, thin strands twisted
around each other like a spiral staircase. The sides are sugar and phosphate
molecules.
What
are the two main parts of a gene?
Each
gene can be broken down into important parts: A promoter, coding region, and
terminator. A gene is one part of a genome. A genome is the collection of all
the genes in a single organism. Promoter: The promoter of a gene contains
information about when to turn the gene on or off.
What
is the role of a gene in the cell?
Genes
are responsible for all aspects of life. Genes are a section of DNA that is in
charge of different functions like making proteins. Long strands of DNA with
lots of genes make up chromosomes. ... Chromosomes are located inside of the
nucleus of cells.
What
are genes? Where are genes located?
The
total complement of genes in an organism or cell is known as its genome, which
may be stored on one or more chromosomes. A chromosome consists of a single,
very long DNA helix on which thousands of genes are encoded. The region of the
chromosome at which a particular gene is located is called its locus.
What
are the components of a gene?
Chemical
structure of genes
Genes
are composed of deoxyribonucleic acid (DNA), except in some viruses, which have
genes consisting of a closely related compound called ribonucleic acid (RNA). A
DNA molecule is composed of two chains of nucleotides that wind about each
other to resemble a twisted ladder.
A
gene is a specific segment of a DNA molecule that holds the information for one
specific protein. ... Different forms of the same gene are called alleles. For
each gene, a human can have two different alleles or two of the same alleles –
one from each parent

Notes:
How could you alter deoxyribonucleic acid without impacting other “acid
components” around it? Are they enclosed in a solid case, which helps to self-contained
and allowed them to edit each one? Personally this is a deadly procedure as you
may cure “a” diseased gene (not all travelling around our body), but you may
alter healthy genes at the same time. I’m not a biologist, btw.
Acid is a liquid. So, it's likely that they
had to locate tiny DNA to pump in more/less, or other acids to alter its
original state. Is this possible to locate and modify those tiny target DNA
with many other tiny DNA around?
Let’s
magnify a DNA to a train. Each wagon is separated and contains different acids.
They must locate the wagon with defected acid to extract or pump in other acids
in order to modify its original state. If they spray acids on the entire train
in order to modify a wagon’s acid, other wagons’ state would be modified or affected
too. There
are also many trains around.
