Which macromolecule provides the blueprint for living things, by storing and transmitting genetic information?

1 answer:

6 0

The nucleic acids (specifically DNA and RNA) are the macromolecule that provides the blueprint for living things by storing and transmitting genetic information.

This is because the genetic information in our bodies is stored in our DNA (deoxyribonucleic acid) undergoes the processes of transcription (where it is transformed into mRNA) and translation (where the mRNA is translated into a polypeptide or protein). These two processes allow the information encoded in our genes to be expressed throughout our bodies through the usage of another macromolecule, the proteins.

Hope this helps!

Which is true of genes? Question 4 options: They are proteins that produce sections of DNA which control the cell's activities.

OleMash [197]

The fundamental and functioning unit of genetics is called genes. They are units of DNA that produce proteins that control the characteristics of organisms.

<h3>What is the role of genes?</h3>

Genes are the basic and fundamental of inheritance and are made up of deoxyribonucleic acid. The variation of the gene of the same trait forms the alleles.

They code for the proteins that produce protein or RNA structures. Genes are located on the chromosome structure and code for proteins that play an important function and role in cell activity.

Therefore, option D. genes are a section of DNA that codes for proteins is correct.

Which one of the following nucleotide pairs would be found in a DNA molecule?

MrRa [10]

Guanine-cytosine is one of the nucleotide pairs that would be found in a DNA molecule. The other is Adenine- Thiamine.

Explanation:

Pyrine bases – Adenine & Guanine- pair with pyrimidines bases – Cytosine and Thiamine. Adenine pairs with Thiamine while Cytosine pairs with Guanine.

In RNA, however, while this same principle of base pairing is observed, rather than Thinmaine, RNA has Uracil in its place. Therefore, in RNA, Adenine pairs with Uracil. There is no Thiamine in RNA.

How does extinction affect evolution?

Semenov [28]

If a species is said to be extinct, then that species is reduced to zero. There are none living in existence. The affects to other organisms of its extinction would depend on their value to the ecosystem. Regardless, extinction completely stops evolution of the species extinct.

Describe how waves superpose on each other using specific examples from two types of waves.

anastassius [24]

Answer:Towhen two waves if nearly same amplitude and same wavelength interfere with each other that time a new wave is formed with a different amplitude this phenomena is known as superposition. If two waves interfere with each other in same phase that time amplitude of resultant wave wave is greater than the component waves and this type of interference is known as constructive interference. And when waves suprpose in opposite phase that time amplitude of resultant wave is less than the component waves and this type of interference is known as destructive interference.

Example: light waves, water waves, sound waves etc

Can you apply what happens to bacteria during antibiotic treatment to other scenarios?

shutvik [7]

Antibiotics stop the bacteria growth, reproduction or destroy the bacteria.

Explanation:

Antibiotics are known as those popular medicine which is helpful and also can fight for certain type of infection. Their main role is to stop their growth, reproduction or otherwise destroyed it.

The first antibiotics was penicillin. Antibiotic is using to stop the allergic reaction but it must be prescribed by doctors. Antibiotics also have side effects. Due to excess use of antibiotics abnormal blood clotting happens.
