Question

Which of the following demonstrates the central dogma of molecular biologists? (1 point)
A.Proteins replicate DNA which gives the expression of traits to an organism.
B.DNA and RNA hold the code to create proteins that are the key to gene expression
C.DNA and RNA mutate into either harmful or helpful effects on the human body.
D.Gene expression relies on environmental factors that determine which traits are dominant.

Answer 1

Answer:

DNA and RNA hold the code to create proteins that are the key to gene expression

Answer 2

The statement that correctly demonstrates the central dogma is: DNA and RNA hold the code to create proteins that are the key to gene expression.

CENTRAL DOGMA:

• The central dogma of molecular biology explains how the information encoded in a gene is used to synthesize proteins for use by living organisms.

• The central dogma relates to gene expression, which involves two major processes namely: transcription and translation.

• Transcription is the synthesis of a mRNA molecule from a DNA template while translation is the synthesis of proteins from mRNA transcript.

• Hence, statement that correctly demonstrates the central dogma is: DNA and RNA hold the code to create proteins that are the key to gene expression.
