What complementary strand of DNA would be produced from the strand of DNA shown below? TCG GA

2 answers:

8 0

Complementary pairing goes like this:

A pairs with T and
C pairs with G. Nothing about this changes unless you get to mRNA (But we won't go into that) :)

So if you have a strand that goes TCG GA then your pairing will look like this:

T A
C G
G C
G C
A T

Hope this helps!! :)

What happens to glucose inside a cell during cellular respiration

Tju [1.3M]

Glucose turns into ATP or ENERGY during the process of cellular respiration ..
<span>The glucose is broken down into 2 molecules of pyruvate, which are two smaller molecules. A net yeild of 2 ATP and 2 NADH result. Each pyruvate is connected to a coenzyme. The resulting molecule is called Acetyl CoA. That reaction also gives off 2 molecules of C02. The Acetyl CoA enters the Krebs Cycle, from which (through a series of steps), 2 more ATP, 6 NADH, 2 FADH2, and 6 CO2 are formed. The 6 NADH and FADH2 (which are coenzymes) move on to the electron transfer chain. Here, they give up their H+ and electrons to the chain. The electrons reduced the proteins on the chain, allowing H+ from outside the cell to be brought in. Bringing this H+ into the cell builds up the concentration. When the concentration gets high enough, the H+ wants to go back out of the cell. The only way to do this is through the ATP synthase. When is passes through this, the synthase combines an ADP with an inorganic phosphate, forming ATP. The typical yeild is 32 ATP from this, giving a total of 36 when you add in the ATP from glycolysis and the Krebs cycle.</span>

At your lab station, you put 30 mL of hydrogen peroxide into three separate beakers and add 2 grams of ground up liver to each o

stepan [7]

Based on the investigation, the inference that can be made about the result is that catalase activity increases with warm temperature.

The liver usually contains an enzyme known as catalase that is capable of breaking down hydrogen peroxide into water and oxygen gas. The bubbles observed in the beaker during the investigation represent the oxygen being evolved from the breakdown of the hydrogen peroxide by the catalase in the liver sample.

At room temperature, a moderate number of oxygen bubbles were observed. The number of bubbles increased with increased temperature as a result of placing the beaker in a warm water bath. At a lower temperature brought by placing the beaker in an ice water bath, no bubbles were observed.

Thus, we can effectively conclude that the activities of the catalase enzyme in the liver increased with a moderately increased temperature.

Which of the following best explains how the expression of a eukaryotic gene encoding a protein wil differ if the gene is expres

Ivan

Answer: c. The protein will be made but will not function, because prokaryotes cannot remove introns.

Explanation:

Eukaryotic cells are cells that have membrane-surrounded organelles, such as a nucleus which is an organelle that stores the DNA, the genetic material. On the other hand, prokaryotic cells do not have a nucleus, and the genetic material is a single molecule, usually circular and closed and double-stranded, which is located in a sector of the cell known as the nucleoid (meaning "similar to the nucleus"), which does not imply the presence of a nuclear membrane.

<u>A gene is a unit of information at a DNA locus that codes for a protein. To synthesize that protein, DNA must be transcribed into messenger RNA (mRNA), and that mRNA is read by ribosomes in a process called translation or protein synthesis</u>. The difference between protein synthesis in prokaryotic and eukaryotic cells is that in prokaryotes, transcription and translation take place directly in the cytoplasm since there is no nucleus. In eukaryotes, transcription takes place inside the nucleus, to generate mRNA. This mRNA molecule is then directed to the cytoplasm where translation happens.

a. In prokaryotic cells, ribosomes are produced in the cytoplasm, whereas in eukaryotic cells they are generated in the nucleolus within the cell nucleus. So they both have ribosomes and they are used to make proteins, then this option is true.

b. RNA polymerase initiates transcription of all different types of RNA (mRNa, ribosomal RNA and transfer RNA). However, there are three RNA polymerase variations, each one translate a different type of gene. But, prokaryotic RNA polymerase can translate eukaryotic genes. Then this option is not true.

c. Prokaryotic cells don't have introns because those cells do not perform a post-transcriptional RNA modifications, only done by eukaryotic cells. One of the modifications is the excision of introns in RNA. An intron is a region of DNA that is part of the primary RNA transcript, but unlike exons, they are removed from the mature transcript prior to translation. <u>So, this remotion does not happen in prokaryotes because they just don't have introns</u>. Also, in prokaryotic cells. the translation and transcription machinery is coupled. So, the transcription and translation occurs simultaneously, there will be no remotion of introns then the protein will be synthesized differently, since the reading frame is changed. Remember that each codon (set of three nucleotides) codes for an amino acid. So if the gene sequence is different because certain sections of the gene have not been removed, the protein will be different, and probably it will not function. This option explains how the expression of an eukaryotic gene encoding a protein will differ if the gene is expressed in prokaryotic cells.

d. The genetic code is the set of rules that defines how a sequence of nucleotides in RNA is translated into a sequence of amino acids in a protein. This code is common to all living organisms, although there are small variations, and it has a unique origin and is universal. So, the code defines the relationship between each sequence of three nucleotides, called a codon, and each amino acid. The sequence of genetic material is composed of four distinct nitrogenous bases, which are represented by letters in the genetic code:

Adenine (A)
Thymine (T)
Guanine (G)
Cytosine (C)
Uracil (U), only in RNA (instead of T)

So, the genetic code is the same for eukaryotes and prokaryotes. So this option is not true.

A 2 L bottle of soda has a volume of 2000 cm³. What is the volume of the bottle in cubic meters?

Svetradugi [14.3K]

Answer:

The answer is

<h2>0.002 cubic meters</h2>

Explanation:

To convert it into m³ we use the following conversion

<h3> $1 {cm}^{3} = 1 \times {10}^{ - 6} {m}^{3}$ </h3>

From the question the value is 2000 cm³

To convert it multiply the value by

1 × 10^- 6m³

That's

<h3> $2000 \times 1 \times {10}^{ - 6} {m}^{3}$ </h3>

We have the final answer as

<h3>0.002 cubic meters</h3>

Hope this helps you
