Everything
you see in the mirror –from your height to your hair color to the dimple (or
lack thereof) on your chin –is return into every cell of your DNA, spiraling
chains of proteins found in every cell in your body. Tank of DNA as your body’s
instruction manual. It tells your cells how to grow into organs, hair, teeth,
fingernails, your tongue and every single other part of your body. Stretches of
DNA (called genes) are like pages in that instruction manual. Genes control
what you will look like, plus less obvious traits such as whether you have
perfect vision or the ability to curl your tongue. Where did I get my genes?
While you admire your good looks in the mirror, don’t forget
to thanks your parents .Genes come in pairs: one from mother and other from
father. It’s the combinations of GENES that bring about –or “express” – various
physical traits (in a process called heredity). Some GENES are more influential
on your appearances than others. The GENES for dark hair are dominant or our
GENES for RED and BLOND hair, making dark hair more common.
Do animals Have DNA?
Yes, all of them do, actually. And not just animals. Every
living thing on earth – including single-celled bacteria, trees and plants- has
DNA in its cells. You might expect to share many GENES with a chimpanzee or
bonobo, our closest living relatives, but did you know you also shares genes
with that banana the chimp is chomping??
Why do some kids look
less like their parents than other kids do?
You
can’t always guess a child appearance just by looking at his or her parents.
The study of GENES- called genetics – is achieving
breakthroughs all the times, but much about heredity remains mysterious.
Combinations of GENES can affect other GENES, leading to unpredictable characteristics
or features that lurk in the genetic background for several generations. Our
GENES are also riddled with so called junk DNA. That doesn’t seem to express
itself in any noticeable way. Environment and diet also play a large Role in
shaping a person’s weight, skin tone, and other physical characteristics.How similar Am I genetically to a CHIMPANZEES (96%-99%) ?
Humans and chimps split from a common ancestors between I3 and 16 million years ago.
How similar Am I
genetically to a FRUIT FLY (60%) ?
Consider this the
next time you swat that itty-bitty bug buzzing around your cantaloupe:you and
that fly are related (so are you and the cantaloupe) fruit files and share many
basic GENES, along with some GENES that might make you more vulnerable to
cancer. Infact scientists are studying fruit files for clues to beating cancer.
How similar Am I
genetically to my pet dog (82%) ?
Dogs might be “man’s
best friend” , but read on for the snocking truth.
How similar Am I
genetically to my pet cat (90%) ?
It turns out humans
shares more genes with felines than with fido.
How similar Am I
genetically to a BANANA (50%) ?
No,this doesn’t mean
you are half banana. All life-forms on earth share fundamental features and
functions at the cellular level.sharing half our GENES with a banana just shows
that we evolved from a common ancestor more than a billions ago.
