Answer:

Splicing of exons and exclusion of introns

-mRNA that is transcribed from DNA usually has large regions of genetic code that just do not code for anything. This is a pretty conserved phenomenon among eukaryotes, to have meaningless sequences of DNA (introns) separating the meaningful sequences of DNA (exons). Introns must be spliced out of mRNA so that its translation leads to a functional protein.

What are the functions of the high-energy electrons in the electron transport chain?
k0ka [10]

Answer:

Transporting Electrons

As the high-energy electrons are transported along the chains, some of their energy is captured. This energy is used to pump hydrogen ions (from NADH and FADH2) across the inner membrane, from the matrix into the intermembrane space. Electron transport in a mitochondrion is shown in Figure below.

Chromosomes and DNA

Chromosomes are DNA wrapped around proteins to form an X-shaped structure.



The diagram will help you see the relationship.

1. Chromosomes are found in the nucleus
2. Chromosomes are made of DNA
3. Sections of chromosomes are called genes



DNA - deoxyribonucleic acid (it is the genetic code that contains all the information needed to build and maintain an organism)





Chromosome Structure







Chromosome Numbers

Each organism has a distinct number of chromosomes, in humans, every cell contains 46 chromosomes. Other organisms have different numbers, for instance, a dog has 78 chromosomes per cell.

Somatic Cells - body cells, such as muscle, skin, blood ...etc. These cells contain a complete set of chromosomes (46 in humans) and are called DIPLOID.

Sex Cells - also known as gametes. These cells contain half the number of chromosomes as body cells and are called HAPLOID

Chromosomes come in pairs, called Homologous Pairs (or homologs). Imagine homologs as a matching set, but they are not exacly alike, like a pair of shoes.

Diploid cells have 23 homologous pairs = total of 46

Haploid cells have 23 chromosomes (that are not paired) = total of 23

Homologous Chromosomes



Sex Determination

Chromosomes determine the sex of an offspring. In humans, a pair of chromosomes called SEX CHROMOSOMES determine the sex.

If you have XX sex chromosomes - you are female

If you have XY sex chromosomes - you are male

During fertilization, sperm cells will either contain an X or a Y chromosome (in addition to 22 other chromosomes - total of 23). If a sperm containing an X chromosome fertilizes an egg, the offspring will be female. If a sperm cell containing a Y chromosome fertilizes an egg, the offspring will be male.

Creation of a Zygote

When two sex cells, or gametes come together, the resulting fertilized egg is called a ZYGOTE

Zygotes are diploid and have the total 46 chromosomes (in humans)

Karyotype

A karyotype is a picture of a person's (or fetus) chromosomes. A karyotype is often done to determine if the offspring has the correct number of chromosomes. An incorrect number of chromosomes indicates that the child will have a condition, like Down Syndrome

Compare the Karyotypes below













Notice that a person with Down Syndrome has an extra chromosome #21. Instead of a pair, this person has 3 chromosomes - a condition called TRISOMY (tri = three)

Trisomy results when chromosomes fail to separate - NONDISJUNCTION - when sex cells are created. The resulting egg or sperm has 24 instead of the normal 23.

Other conditions result from having the wrong number of chromosomes:

Klinefelters Syndrome - XXY (sex chromosomes)

Edward Syndrome - Trisomy of chromosome #13

The​ half-life of​ carbon-14 is 5600 years. If a piece of charcoal made from the wood of a tree shows only ​% of the​ carbon-14
Leokris [45]

Mature and established trees die for a combination of reasons but sudden browning of foliage is typically associated with a lack of water supply to the canopy. Water supply can be cut off to the canopy due to obvious issues including deficiency or root damage.

<h3>What is Carbon?</h3>
  • Carbon is a chemical component with the symbol C and atomic number It is nonmetallic and tetravalent—its atom makes four electrons unrestricted to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon produces up only about 0.025 percent of Earth's crust.
  • Carbon is employed in some way in almost every industry around the globe. It is used for fuel in the form of coal, methane gas, and crude oil (which is used to produce gasoline). It is used to make all sorts of fabrics including plastics and alloys such as steel (a mixture of carbon and iron).
  • Carbon is a chemical element with the symbol C and atomic number 6. Categorized as a nonmetal, Carbon is a solid at room temperature.
