These genes could have arisen by gene duplication.

<h3>What is gene duplication?</h3>

Gene duplication is the process of copying a section of DNA that codes for a gene. A retro transposition event or a recombination mistake are both potential causes of gene duplication. As a result, the duplicate gene coding may experience a significant number of modifications throughout time. This might prevent the gene from functioning or, in other situations, give the creature a benefit.

Gene duplication is a phenomenon that can happen through a variety of ways:

  • Ectopic Recombination: Uneven crossing-over between misaligned homologous chromosomes during meiosis might result in duplications. A duplication at the exchange site and a reciprocal deletion are the results of this recombination.
  • Replication Slippage: Short genomic sequences can be duplicated as a result of the replication error known as replication slippage. DNA polymerase starts copying the DNA during replication, but eventually the polymerase separates from the DNA, causing replication to stall. The replicating strand is incorrectly aligned when the polymerase reattaches to the DNA strand, which accidentally results in several copies of the same portion.
  • Aneuploidy: When a single chromosome's nondisjunction causes an abnormally high number of chromosomes, this condition is known as aneuploidy. Aneuploidy is frequently damaging and frequently causes spontaneous miscarriages in mammals. Some aneuploid people can survive. For instance, human trisomy 21 causes Down syndrome but is not lethal.

Consider this animal cell.<br> Which organelles are labeled G?
Paraphin [41]

Answer:

In the animal cell the organelles that is  labelled G is mitochondria.

Explanation:

Mitochondria are the membrane bound organelles with inner membranes folded inside which can form finger like structures called cristae. There numbers are more in the cell. They are basically responsible for the production of the energy, hence called as the power house of the cell. They also perform the cellular respiration, which means it takes the nutrients from the cell breaks it and makes energy from it. This energy is used by the cell to carry out various life processes.

Write a 225 word report on why each of the factors (R, K, L, S, C, and P) are important factors needed to determine the amount o
Lostsunrise [7]

Answer:

The R, K, L, S, C, and P factors are -

R - the rainfall erosivity factor,

K - soil erodibility factor

L- the topographic factor derived from slope length

S -the topographic factor derived from slope gradient

C- the cover and management factor

P - the erosion control practice factor

Explanation:

The R, K, L, S, C, and P factors are -  

R - the rainfall erosivity factor,  which depends on geographic location. The greater is the intensity and duration of the rainfall, the higher will bethe erosion potential.  

K - soil erodibility factor,  K signifies the soil loss in tonnes/hectare (tons/acre) for any agricultural land that is cultivated and has a slope length (assumed) of 22.13 meters and slope steepness of 9%. K represents the susceptibility of a soil particle to be easily detached from the surface and carried away by rainfall and runoff. The greater is the value of K , the greater is the erodibility of the soil particles.

L- the topographic factor derived from slope length, It signifies the extent of soil being carried away when slope lengths is greater than an assumed slope length of 22.13 meters. The longer the slope , the higher is the rate of erosion.  

S -the topographic factor derived from slope gradient, It signifies the extent of soil being carried away when slope steepness is greater than an assumed slope steepness of 9%. The steeper the slope , the higher is the rate of erosion.

C- the cover and management factor, It states how effective soil and crop management systems is in terms of preventing soil loss. It is a ratio of soil loss from land under a specific crop and management system to corresponding loss from continuously fallow and tilled land. The higher the C value, the lower is the management process quality to prevent soil erosion

P - the erosion control practice factor,  It represents the after effects of practices pertaining to reduce erosion by reducing the amount and rate of the water runoff. The lower the P value, the better is the effects of practices pertaining to reduce erosion
