Answer:

The Nitrogenous Bases

Explanation:

DNA is a <em>double helical structure</em>, comprising nitrogenous bases, phosphate groups and deoxyribose sugars. A phosphate group is attached to a nitrogenous base and a deoxyribose sugar to form a nucleotide.

There are four types of nitrogenous bases in the DNA sequence. These are:

  • Adenine
  • Cytosine
  • Guanine
  • Thymine

The deoxyribose sugar ensures the structural integrity of a nucleotide however, DNA is arranged such that the nitrogenous base of one nucleotide, is attached to the nitrogenous base of another nucleotide, pairing in a pattern known as complementary base pairing.

Adenine pairs with Thymine and Cytosine pairs with Guanine. This pairing, gives the continuous ladder appearance to DNA strands.

Answer:

The parts of a nucleotide that touch the feet when climbing are the four nitrogenous bases, namely: adenine, thymine, guanine and cytosine

Explanation:

The "handrails" of the DNA ladder are made of sugar phosphate, which protects the information in which the "steps" are transported. Each unit of sugar phosphate is attached to the next with a covalent bond.

Among the "handrails" of the DNA ladder are weaker hydrogen bonds that connect the two halves of the "steps." The "steps" of the DNA ladder are made of the nitrogenous bases: adenine, thymine, guanine and cytosine. Among them they form complementary pairs, for example, adenine binds with thymine, and guanine with cytosine.

2. Write these functions definitions:
GREYUIT [131]

Answer:

Complete the code with the following code segment:

void add2Numbers(){

   int num1, num2;

   cout<<"Enter any two numbers: ";

   cin>>num1>>num2;

   cout<<num1+num2;

}

void sub2Numbers(){

   int num1, num2;

   cout<<"Enter any two numbers: ";

   cin>>num1>>num2;

   cout<<num1-num2;

}

void mul2Numbers(){

   int num1, num2;

   cout<<"Enter any two numbers: ";

   cin>>num1>>num2;

   cout<<num1*num2;

}

void div2Numbers(){

   int num1, num2;

   cout<<"Enter any two numbers: ";

   cin>>num1>>num2;

if(num2==0){

cout<<"Division by 0 is invalid";

}else{

   cout<<(float)num1/num2;}

}

Explanation:

The function added to this solution are:

  • add2Numbers
  • sub2Numbers
  • mul2Numbers
  • div2Numbers

Each of the functions

  • declares two integers num1 and num2
  • prompt user for inputs
  • gets user inputs from the user

For add2Numbers() function:

This line adds the two integer numbers and prints the result

   cout<<num1+num2;

For sub2Numbers() function:

This line subtracts the two integer numbers and prints the result

   cout<<num1-num2;

For mul2Numbers() function:

This line multiplies the two integer numbers and prints the result

   cout<<num1*num2;

For div2Numbers() function:

This if condtion checks if the denominator is 0

if(num2==0){

If yes, the following is printed

cout<<"Division by 0 is invalid";

If otherwise, the division is calculated and the result is printed

   cout<<(float)num1/num2;

Answer: Proxy server

Explanation: Proxy server is a type of server that is acts as interface between the network on huge scale and any local network. This server provides the feature of security, operations, privacy etc in the network system. They also help in improving the performance of the network.

It can work as the web filter to eliminate the unwanted websites.They acts as the gateway by  observing the website that is being browsed by the other user.Thus installation of proxy server should implemented on the organization.

Python - Please help!
Margaret [11]

Answer:

i= 1

for i in range(1,n):

     if i * i < n:

           print(2* i + 1)

     i += 1

else:

     print('Hakuna Matata')

Explanation:

First, there's a need to rewrite the code segment in your question (because of indentation)

<em>i= 1</em>

<em>while i*i < n:</em>

<em>      print(2* i + 1)</em>

<em>      i += 1</em>

<em>else:</em>

<em>      print('Hakuna Matata')</em>

<em />

The explanation of the equivalent of the above while loop is as follows

This line initializes i to 1

i= 1

This line iterates from 1 to n-1

for i in range(1,n):

This line checks if i * i is less than n

     if i * i < n:

The following line is executed if the above condition is satisfied; otherwise, nothing is done

           print(2* i + 1)

The value of i is incremented by 1 using this line

     i += 1

The following is executed at the end of the iteration

else:

     print('Hakuna Matata')

<em>Note: Assume any value of n, both programs display the same output</em>
