Answer:

A change of the sequence of nucleotides in a DNA segment is called a mutation. This could change whether certain proteins are made that support the body or not.

Answer:

It would change the nucleotide sequence of the transcribed mRNA

Explanation:

During the process of transcription, a DNA template is used to synthesize a mRNA molecule. The nucleotides in the DNA molecule undergo a complementary base pairing to form the nucleotides on the mRNA. This means that the order of sequence on the DNA determines the order of sequence on the mRNA.

In a case where the nucleotide sequence of a DNA segment changes in the process of MUTATION, the sequence of nucleotides in the mRNA strand will also change. For example, if sequence: ATT on the DNA produces UAA on the mRNA, a change to AAT on the DNA will cause the mRNA sequence to change to UUA.

Chantel dropped a tiny spot of ketchup on her pants during lunch. Even though her teacher was able to completely remove the spot

Lerok [7]

Answer:

Chantel dropped a tiny spot of ketchup on her pants during lunch. Even though her teacher was able to completely remove the spot, Chantel cries hysterically and says that she wants to go home because her outfit is ruined. Chantel's reaction is an example of <u>"Invisibility."</u>

Explanation:

The kid is unable to understand the action, as chantel is unable to figure what to do now and tries to escape from the whole situation at the moment which brings great distress along with it and makes it a preoperational situation termed as invisibility.

During DNA replication, DNA polymerase III can only add nucleotides in:

Alekssandra [29.7K]

Option A

DNA is always synthesized in the 5' to 3' direction, meaning that nucleotides are added only to the 3' end of the growing strand.
