What is the structure of DNA? 20 points.

Answers

Answer 1

Answer:

Basic structure of DNA

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

DNA structure and function

DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.

Explanation:

DNA is made up of molecules called nucleotides. Nucleotides are attached together to form two long strands that spiral to create a structure called a double helix. If you think of the double helix structure as a ladder, the phosphate and sugar molecules would be the sides, while the bases would be the rungs.

Answer 2
it is called nuclideds they each claim a group

How is DNA created?(short answer)

Answers

Explanation:

For a strand of DNA to form, nucleotides must be linked into chains, with the sugar phosphate groups alternating. DNA is made of the building block chemical called nucleotides. Nucleotides are made up of three main parts, a sugar group, a phosphate group, and some type of nitrogen base. Hope this answers, and is helpful! Have a great day! :))

Answer:

the total resistance is 12 ohms

Amps = 1 amp

Explanation:

resistor in series add  so the total resistance is 12 ohms

E=I x R   E = voltage, I = amps, R = resistance

12 = I x 12

I=1

1 amp

resistor in series add  so the total resistance is 12 ohms

E=I x R   E = voltage, I = amps, R = resistance

12 = I x 12

  I=1 is the correct answer

How important is it for a cell to maintain the same number of chromosomes? Explain.

Answers

Answer:

It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set. Before mitosis, the chromosomes are copied.

a block of wood has a mass of 6 .0 and a volume of 12 .0 CM what is the density Of the block of wood


Brainly will be given

Answers

Answer:

[tex]\boxed {\boxed {\sf d=0.5 \ g/cm^3}}[/tex]

Explanation:

Density is equal to mass over volume.

[tex]d=\frac{m}{v}[/tex]

The mass of the wood is 6.0 grams and the volume is 12.0 cubic centimeters.

[tex]m= 6.0 \ g \\v= 12.0 \ cm^3[/tex]

Substitute the values into the formula.

[tex]d=\frac {6.0 \ g}{12.0 \ cm^3}[/tex]

Divide.

[tex]d=0.5 \ g/cm^3[/tex]

The density of the wood is 0.5 grams per cubic centimeter.

A scientist is examining layers of the
earth and tracking information about
animal fossils found in each layer. For
many of the deeper layers there are
consistently large animal skulls but
there is a sudden shift in the skull size in
one layer and they are all much smaller
at that point for the remaining layers
until the earth's surface. What does this
suggest?

Answers

This suggests that sudden change that occur to the environment cause a different size animal to become the main species of that area.

Why the fossils of small skull organisms were found?

This is because at that particular environment the small skull organisms can survive at that time as compared to big skull animals. The presence of a specific type of fossil in the soil layer shows that the fossil organism live at that time on this area due to the presence of good environmental conditions so we can conclude that environment was good for the small skull organisms at that time.

Explain why it is necessary that gametes (egg cells and sperm cells) have half the DNA that normal body cells have.​

Answers

Answer:Gametes are reproductive cells, such as sperm and egg. As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.
