Answer:

interspersed, transposon-derived repeats, simple sequence repeats.

Explanation:

In the human genome, not only the protein coding genes are present, in fact these genes make up just a very little portion of the human genome about 1.5-2% of the entire human genome. Repeats make up about 48% of the human genome which is the largest and the rest include, conserved non coding sequences (43.5%), heterochromatin regions etc.  

Some of the repetitive elements includes LINEs, SINEs, DNA fossils tranposoon, Retrovirus like elements. all these are transposable elements which are  mobile DNA sequences that can migrate to different  regions/areas of the genome.

Microsatellites (simple sequence repeats) are tracts of repetitive DNA in which certain DNA motifs are repeated normally 5-50 times.

Assuming DNA is replicated correctly (so there are no mutations),
gavmur [86]

Answer:

None of the choices would lead to all identical gametes.

Explanation:

Gametes are sex cells produced by sexually reproducing organims via a process of cell division called MEIOSIS. Meiosis is a cell division process which produces four (4) daughter cells (gametes), which are genetically different from the parent cell.

The difference in genetical content is as a result of a process unique to only meiosis called CROSSING-OVER OR RECOMBINATION. This process ensures that the genetic content of the gametes are altered. Hence, since gamete formation is done via meiosis, none of the scenarios in the option will lead to all identical gametes.

A species that has experienced a severe bottleneck event would be expected to _______.. a.. be better able to adapt to changing
romanna [79]

Answer;

C. Be more susceptible to disease and famine

Explanation;

-A species that has experienced a severe bottleneck event would be expected to be more susceptible to disease and famine.

-The Bottleneck Effect occurs when there is a disaster of some sort that reduces a population to a small handful, which rarely represents the actual genetic makeup of the initial population.

-It may be caused by various events, such as an environmental disaster, the hunting of a species to the point of extinction, or habitat destruction that results in the deaths of organisms.

saveliy_v [14]

Answer: By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.

List what Eukaryotic cells and prokaryotic cells have.
wolverine [178]

Answer:

Summary

All cells have a plasma membrane, ribosomes, cytoplasm, and DNA.

Prokaryotic cells lack a nucleus and membrane-bound structures.

Eukaryotic cells have a nucleus and membrane-bound structures called organelles.

Explanation:

Eukaryotic Cells

Eukaryotic cells usually have multiple chromosomes, composed of DNA and protein. Some eukaryotic species have just a few chromosomes, others have close to 100 or more. These chromosomes are protected within the nucleus. In addition to a nucleus, eukaryotic cells include other membrane-bound structures called organelles. Organelles allow eukaryotic cells to be more specialized than prokaryotic cells. below are the organelles of eukaryotic cells , including the mitochondria, endoplasmic reticulum, and Golgi apparatus.

Prokaryotic cells are usually smaller and simpler than eukaryotic cells. They do not have a nucleus or other membrane-bound organelles. In prokaryotic cells, the DNA, or genetic material, forms a single large circle that coils up on itself. The DNA is located in the main part of the cell.
