Which of the following accurately describes a step within transcription?A. DNA polymerase uses one strand of RNA as a template to put together nucleotides.B. The RNA strand is produced within the cytoplasm.C. The DNA strand is used as a template for which a complementary RNA strand can be produced.D. The RNA strand forms a template by which DNA can be built

Answers

The statement "The DNA strand is used as a template for which a complementary RNA strand can be produced" accurately describes a step within transcription (option C)

What is transcription?

Transcription is the process of copying genetic information from DNA into RNA. The DNA strand is used as a template, and the RNA polymerase enzyme reads the DNA strand and adds complementary nucleotides to form a new RNA strand.

The RNA strand is then released from the DNA and can be used to make proteins.

The enzymatic breakdown of any type of food molecule is called ________.A. diffusion
B. active transport
C. hydrolysis
D. denatured

Answers

Hydrolysis occurs in the presence of enzymes (organic compounds that generally increase the rate of chemical reactions) called hydrolases.

What is the hydrolysis?

It is a basic process of digestion and consists of the addition of water molecules to polysaccharide, fat or protein by specific enzymes that convert it into glucose, fatty acid and amino acid, respectively.

Characteristics of hydrolysis

  • It consists of the conversion of large nutrient molecules into small ones that are possible to absorb.

Therefore, we can conclude that digestion consists of hydrolysis, a water molecule is introduced to break bonds in large molecules by the action of specific enzymes.
