Answer:

DNA:

Dexoyribonucleic acid is the genetic material of almost all the organisms except some virus. DNA contains deoxyribose sugar that lacks 2'OH group on second carbon. The nitrogenous base pair of DNA are adenine, guanine, thymine and cytosine. DNA cannot acts as an enzyme.

RNA:

Ribonucleic acid is present as genetic material in few viruses only. RNA contains oxyribose sugar that has 2'OH group at second position. The nitrogenous base pair of RNA are adenine, guanine, uracil and cytosine. RNA can acts as any enzyme in biological reactions.

The difference is that deoxyribose sugar has one less oxygen than a normal ribose sugar. RNA's nucleotides are composed of Uracil an alternate nitrogenous base to Thymine. So the sequence of nitrogenous bases is composed of Adenine, Uracil, Cytosine, and Guanine opposed to Adenine, Thymine, Cytosine, and Guanine.

This structure encapsulates the pituitary gland to aid in protection and diffusion of releasing hormones from the anterior pituitar is Sella Turcica.

Sella Turcica it is very important during embryological development , mainly help in migration of Neural crest cell to frontonasal . This neural crest help in development of teeth and Sella Turcica

What is Neural crest cell ?

A multipotent and migrating cell population called neural crest cells (NCCs) helps the developing embryo generate a variety of tissues. A group of disorders and illnesses called as neurocristopathies are caused by flaws in the growth, differentiation, and migration of NCCs.
Found in ectoderm in the margin of the neural tube
Contribute in the formation of a plethora of different tissues and organs

Explain how dna polymerase chooses which nucleotides to put into the new strand. Be specific and detailed in your explanation of

Free_Kalibri [48]

DNA polymerase adds nucleotides at the 3' primer end of the DNA. This DNA polymerase checks the newly added base has correctly paired with the base in the template strand or not. Based on this it adds the new nucleotide.

<h3>What is nucleotide?</h3>

Nucleotide is the nucleoside with a phosphate group. It generally stack or link with each other to make a polynucleotide chain.

DNA polymerase adds these nucleotides one by one to the 3' primer end on the DNA strand.

It usually checks the correct pairing of the base with the template strand and then adds the new nucleotide to it.

Thus, by this step DNA polymerase choose nucleotides to put into the new strand.
