How many hydrogen bonds are found between a-t

Biology
1 answer:
ludmilkaskok [199]3 years ago
4 0

The correct answer is two hydrogen bonds between adenine and thymine (the bond is thus weaker and longer) and three between cytosine and guanine.

A hydrogen bond is a bond formed between a hydrogen (H) atom and electronegative atom or group, such as nitrogen (N), oxygen (O), or fluorine (F).

Hydrogen bond is found in the double helical structure of DNA between its base pairs. Guanine is complementary linked with cytosine and adenine with thymine. Thanks to hydrogen bonds one complementary strand is connected to the other and replication is enabled.

mamaluj [8]

Answer:

There are many questions that can be answered by science but I will provide some examples below.

Explanation:

Science involves many areas of study, <u>from biology and chemistry to physics and neuroscience</u>. Generating questions and providing answers are the most important steps in science as this process has allowed thousands of scientists to develop new drugs to treat previously-mortal diseases, to protect endangered species, to prevent population declines, to understand the behavior of fauna, among many other remarkable outcomes and discoveries.

In this answer, I will focus on some questions belonging to the life sciences areas that can be answered by science:

Pepsin is an enzyme found in the human stomach that breaks down protein. Pepsin will not break down starch.
Andre45 [30]

The statement which best explains why Pepsin will not break down starch is that enzymes only work for specific substrates.

<h3>What is an Enzyme?</h3>

This is referred to as a biological catalyst which helps to speed the rate of chemical reaction in the body by lowering the activation energy needed to start it up. it is also proteinous and can be denatured by heat and other substance such as chemicals.

They are also substrate specific which means they can't act on any type of substance. For example enzyme such as amylase acts on only starch while pepsin acts on only protein.
