Which of the following strands is the complementary strand to AGG – CTA – AAC?

2 answers:

6 0

The DNA (Deoxyribonucleic acid) have complementary stands which are spirally bound to each other. The nucleotides held these two strands of the DNA together. The four nucleotides of the human DNA includes the adenine (A), guanine (G), thymine (T), and cytosine (C). The adenine forms hydrogen bond with thymine and the guanine forms bond with cytosine. Hence, the complementary strand of the AGG-CTA-AAC will be TCC-GAT-TTG.

Hence, the answer is 'Option D - TCC-GAT-TTG'.

Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN

Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

In any one species, the amount of adenine closely approximates that of thymine.
In any one species, the amount of guanine closely approximates that of cytosine.
The amounts of A, T, G, and C in DNA varies from species to species.

(options A, B and D)

Explanation:

Organizing the data has to:

Source of DNA A T G C

Streptococcus 29.8 31.6 20.5 18.0

Yeast 31.3 32.9 18.7 17.1

Herring 27.8 27.5 22.2 22.6

Human 30.9 29.4 19.9 19.8

E. Coli 24.7 23.6 26.0 25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

What does reverse transcriptase use to form dna apex?

Marianna [84]

Reverse transcriptase use mRNA to form DNA apex

Reverse transcriptase is a broad family of enzymes that play a unique role in the flow of genetic information. The synthesis of DNA from an RNA template through reverse transcription produces complementary DNA. Reverse transcriptase use an RNA template and a short primer complementary to the 3' end of the RNA to direct the synthesis of the first strand complementary DNA, which can be used directly as a template for the Polymerase Chain Reaction.

The chemical equation shown represents photosynthesis.

Delicious77 [7]

Answer: Option B; It traps light energy and converts it into chemical energy.

This substance is chlorophyll. It is a pigment present in leaves of all plants. It absorbs light energy and provides it to carry out the process of photosynthesis. Light energy is converted into chemical energy, in form of NADPH and ATP, which can be used by plants for photosynthesis.

This pigment is present only in plants, so option A is incorrect.

This pigment only absorbs and transfers energy to other molecules, and is not associated with carbon dioxide directly, so option C and D are also incorrect.

What is produced during the photosynthesis process?

7nadin3 [17]

Answer:

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
