What is prokaryote and eukaryote? give there characteristic .
igor_vitrenko [27]

Answer & Explanation:

<u><em>Prokaryote</em></u>: a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and cyanobacteria.

<u><em>Characteristic of prokaryote</em></u>: lack an organized nucleus and other membrane-bound organelles. Prokaryotic DNA is found in a central part of the cell called the nucleoid. The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration.

<em><u>Eukaryote</u></em>: an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria.

<u><em>Characteristic of eukaryote</em></u>: larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes

Describe the key features of the Watson-Crick model for DNA structure.
vagabundo [1.1K]

Answer:

Watson and Crick proposed the double helical model of DNA.

Explanation:

- This model says that DNA exist as double helix. It has two polynucelotide strands running in opposite direction i.e the strands are anti-parallel.

- Each polynucleotide strand is made up of several nucleotide liknked together by phophodiester bonds.

- The two strands are not coiled upon each other but the double strand is coiled upon itself around a common axis like the spiral stair case. Here base pairs forms the stairs and backbone of two strands form railing. Back bone contains sugar and phosphate.

- The base pairing is specific, adenine always pairs with thymine and guanine always pairs with cytosine. Thus if we see any base pair, it consists of one purine and one pyrimidine.

- The two strands of DNA thus show complementary base pairing.

- The strands are held together because of hydrogen bonding between the bases in opposite strand.

- One full helical turn involves ten base pairs and the base pairs are stacked  3.4 A apart.

- This form is called as B-form of DNA.

Softa [21]

Plate tectonic induced changes in the sea level could increase the total percentage of land area upto 40% or decrease it to as low as 17%

<h3>What are Tectonic plates?</h3>

Plate tectonics, whose name derives from the Late Latin tectonicus and the Ancient Greek letter v, which means "pertaining to building," According to the widely accepted scientific idea , the Earth's lithosphere is made up of many major tectonic plates that have been gently shifting for nearly 3.4 billion years

The model is based on the idea of continental drift, which was created in the early 20th century. After seafloor spreading was confirmed in the mid- to late 1960s, plate tectonics became largely accepted by geoscientists.
