castortr0y [4]4 years ago
4 0

Answer:

The correct answer is option b. "cause a change in the reading frame of mRNA codons".

Explanation:

Frameshift mutations are among the most drastic mutations because in most cases, result in the translation of a completely different protein. Frameshift mutations are the result of insertions or deletion of one or more nucleotides, resulting in a change in the reading frame of mRNA codons. In consequence, the ribosome translates a different amino acid sequence, based on the new reading frame of mRNA codons.

A small segment of DNA is used as a template for transcription. This DNA contains the base sequence CGT. If an mRNA transcript i
kramer

Answer:

The correct answer is: CGU.

Explanation:

Transcription is the process in which a specific DNA segment is taken and copied into RNA. This is highly important since proteins are made thanks to RNA and not DNA.

If an mRNA were to be transcripted using a segment of DNA containing CGT,<u> it would form a GCA codon</u>. The DNA strand serves as a model to synthesize the RNA strand, similar to how DNA replication happens, except RNA ends up having only one strand.

<u>Since mRNA will have a GCA codon, the tRNA anticodon will be CGU</u> (uracil replaces thymine).
