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

Deletion
Substitution

Question 1: The statement that best demonstrates the central dogma of molecular biology is: DNA and RNA hold the code to create proteins that are the key to gene expression.
Question 2:
The type of mutation shown in the sequences can be identified by comparing the original DNA sequence (TTA-GCG-ATC) to the copied sequence (AAC-TCG-CTA-G). Noticing that there is an extra nucleotide (the "G") in the copied sequence, it indicates the addition of nucleotides, which aligns with:
Insertion.
