The twisted ladder shape of DNA
A.
triple helix
B.
helical ring
C.
double helix
D.
hexagonal ring

Answers

Answer 1

Answer:

C. Double helix

Explanation:

The twisted ladder shape that DNA has can also be called a double helix.

It is in the shape of a helix, which is similar to a 3D spiral shape.

It is called a double helix because DNA is made up of two DNA helix strands that are intertwined.

So, C is the correct answer.

Answer 2

Answer:

The answer is C. double helix.

Explanation:

DNA is constructed through two threads or strands winded around each other in the shape of a twisted ladder - hence one of the shape of a DNA's most prominent nicknames (that is, twisted ladder). Additionally, it is even more commonly known as a double helix. In fact, the term double helix was especially created to describe DNA!

What is meant by the term “essential” amino acids, what is essential about them? Put in your own words

Answers

Amino acids make up proteins, and proteins are needed for proper growth in humans. They’re essential because, without them we wouldn’t have the nutrients we need to survive. I hope this helped!
Essential amino acids are the ones that your body can’t make on its own. These are ones that come from food and need to be obtained in order to survive. Your body needs these acids because they are like building blocks of proteins and they’re needed for vital processes like building proteins and synthesis of hormones and neurotransmitters.

Answers

Answer:

The human genome contains around 30 000 genes, each of which codes for one protein. Large stretches of DNA in the human genome are transcribed but do not code for proteins. ... The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.

Protein molecules are the building blocks of the body. They are made up of long chains of amino acids. Draw the general structure of an amino acid.

Answers

Answer:

Please find the diagram of the general structure of amino acids attached.

Explanation:

Proteins are one of the four major biomolecules in living systems. As rightly stated in this question, they are building blocks of the body. However, proteins are biological polymers made up of monomeric units called AMINO ACIDS. A long chain of these amino acids make up a protein molecule.

An amino acid generally consists of a central carbon atom called ALPHA CARBON, attached to an amine group (-NH2), a carboxylic acid group (-COOH), and a side chain (R side chain). All 20 amino acids that exists in nature have this general structure but differs only in the type of SIDE CHAIN (R group) they possess i.e. all amino acids have a different R side chain.

Please find the diagrammatic representation of the general structure of amino acids as an attachment.

Fingers crossed

Please help!!! Happy holidays

Answers

Answer:

B. From 200 m to the surface

Explanation:

Photosynthesis is a process which is light-dependent. Therefore, regions where light availability is not sufficient or event absent will not support photosynthesis.

In the oceans, light availability decreases with increasing depth. Below, a certain depth in the ocean, light availability becomes insufficient to support photosynthesis and this is usually below 200 m. The uppermost region of the ocean from 200 m to the surface of the ocean is sufficiently illuminated to permit photosynthesis by phytoplankton and plants. This region is called the euphotic zone.

Therefore, from the attached image, the correct option is B, since it represents the euphotic zone of the ocean.

What statement best explains how the traits of an organism are determined by the DNA in each of their cells? Answer F DNA is translated into a strand of mRNA, which is used to control cellular functions G The information from DNA is used to determine the amino acid sequence of proteins H The hydrogen bonds of DNA are broken to provide the energy for protein synthesis. J The DNA double helix is unzipped, and each strand codes for a single protein.

Answers

Answer:

The information from DNA is used to determine the amino acid sequence of proteins

Explanation:

DNA is the genetic material of living organisms, which serves as a storage molecule for the genetic information needed to synthesize useful products (proteins). The information in the DNA, however, must undergo GENE EXPRESSION in order to be decoded.

The process of gene expression involves two major processes viz: transcription and translation. Transcription is the process by which DNA is used as a template to synthesize mRNA molecule while Translation is the process by which mRNA is used to synthesize amino acids, building blocks of proteins. Hence, the information from DNA is used to determine the amino acid sequence of proteins.

What medium does sound waves travel the fastest
In (solid, liquid, or gas) why?

Answers

Answer:

Sound travels fastest in solids and slowest in air. Water is in between. This is because the particles in solids are closer together than the particles in liquids or gases, and the particles in liquids are closer together than the particles in gases. The tighter particles are packed in a space, they collide more frequently. This allows sound, which is simply the combined collisions of particles, to travel fastest in solids. So, to reiterate, sound travels fastest in solids, then water, and slowest in air.
