The progression of a cell by the cycle of cell is regulated by the protein family Cyclic
Explanation:
- In the year 1982, Cyclin was located by Timothy Hunt as a family of proteins which has a vital function in the progression of a cell.
- CDK enzymes or ‘cyclin dependent kinase’ gets activated by it that synthesizes the cycle of the cell.
- The concentration of this protein moves in a cyclic way in the cell cycle. No enzymatic function is seen in them but it aims at CDK’s different location.
Answer:
The correct answer will be option- synaptonemal complex.
Explanation:
The tetrad arrangement of the genetic material in an organism is mediated by a highly conserved structure known as the synaptonemal complex. The synaptonemal complex is formed during the prophase I of the meiosis I which attaches the chromatin of the homologous chromosomes.
The synaptonemal complex is a proteinaceous structure which is formed by the two lateral ladders like elements with a central portion composed of the central element. The chromatin gets attached to the lateral elements while the central a portion bridge space between the two ladders thus help in the formation of the tetrad.
Thus, option- synaptonemal complex is the correct answer.
The age group she does fit in is Infancy
Answer:
Average annual temperature in US cities would range between 50-70 degrees Fahrenheit
Explanation:
There are several factors that can influence the temperature of city in general. Higher altitude has a lower temperature because it has less air density and absorbs less sunlight. The city latitude coordinate also determines how much sunlight they will get. The closer the city to the equator, the more sunlight they can get.
Distance to the sea will influence the rate of rainfall and also influence temperature. Ocean currents can move hot water from other regions too.
