In transparency 19a how does the protein labeled point mutation differ from the normal protein

When a point mutation occurs, the protein may differ from a normal protein by two characteristics:

Explanation:

Point mutation is the change in a single nucleotide in the chain. Guanine can be paired with Timine, Adenine with Cytosine and vice versa. This type of mutation is usually due to errors in DNA replication. Its consequences can be silent (the generated mRNA, although it also contains the altered information, results in the formation of the same protein), non-silent or “missense” (the mutation in the DNA ended up leading to the alteration of the amino acid sequence that constitutes the protein , being able to change its structure and function) or meaningless, also called “nonsense” mutation (when changing base pairs generated information for “stop code”, used to signal the end of protein synthesis and, thus, the protein runs out of amino acids in its chain and thus no function).

all answers true and false

explanation:

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers
