What structure is most important in forming the tetrads?
Vladimir79 [104]

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.

Alexus [3.1K]

Topographic maps and satellite images

Explanation:

A topographic map represents earth's surface features like land forms and structures, rivers and lakes, mountains and hills, elevations and other natural features along with man-made artificial features like cities, buildings, monuments, roads, bridges etc. These are formed by contour lines.

Topographic maps are printed with revision dates to observe the changes happening on the Earth's surface. Various land forms keeps changing due to natural and man-made causes and these needs to be updated accordingly to provide accurate details.

A satellite image provides details of the earth aerially from space. These provides details of a land form or any earth structure currently.
