Because it makes accessing them easier for the cell, it is assumed that the bases will be on the outside of the DNA molecule.

<h3>What is DNA molecule?</h3>
  • Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.
  • Each nucleotide is made up of a phosphate group, a deoxyribose sugar, and one of the four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).
  • An alternating sugar-phosphate backbone is created when the nucleotides are linked together in a chain by covalent connections (also referred to as the phospho-diester linkage) between the sugar of one nucleotide and the phosphate of the next.
  • To create double-stranded DNA, the nitrogenous bases of the two distinct polynucleotide strands are joined by hydrogen bonds in accordance with the base pairing principles (A with T and C with G). Pyrimidines and purines make up the two families of complimentary nitrogenous bases.

A section through the renal cortex can be identified quickly by the presence of
Kazeer [188]

Answer:

Renal capsule.

Explanation:

The renal capsule is known as a fibrous layer. That fibrous layer helps to cover the kidney in a layer of perirenal fat (known as the adipose capsule). The renal cortex is known as the outer part of the kidney where ultrafiltration occurs. It is present between the renal medulla and the renal capsule.

The renal capsule is important for the physiological function of the kidney in the human body. It helps to influence interstitial pressure and consistently tubular reabsorption of water and sodium.

with reference to the role of oncogenes, explain how the normal controls over the cell cycle can be lost.
Katena32 [7]
<span>#1) With reference to the role of oncogenes, explain how the normal controls over the cell cycle can be lost.

Answer: The way that cell cycle can be lost is by going through changes in the activity of cell cycle regulators. Cancer causes different types of mutations. There are two types of cell cycle regulators that can promote the development of cancer:

-Positive Regulators that can be over activated (become oncogenic).
-Negative Regulators (tumor suppressors) which can be inactivated.

I hope it helps, Regards. <span /><span>
