EOC Review #4: Protein Synthesis and Mutations

Front

What is the role of RNA in protein synthesis?

Back

RNA serves as a template for translating genetic information into proteins, facilitating the process of protein synthesis.

Front

What is the start codon in mRNA and what amino acid does it code for?

Back

The start codon is AUG, which codes for the amino acid Methionine.

Front

Define mutation in the context of DNA. What are the potential effects of mutations?

Back

A mutation is a change in the DNA sequence that can lead to alterations in protein structure and function, potentially causing diseases or changes in traits.

Front

What is the difference between insertion and deletion mutations?

Back

Insertion mutations add one or more nucleotide bases to the DNA sequence, while deletion mutations remove one or more bases.

Front

How many nucleotides are in a codon?

Back

A codon consists of three nucleotides.

Front

What is the significance of the genetic code chart?

Back

The genetic code chart shows the correspondence between mRNA codons and the amino acids they code for, guiding protein synthesis.

Front

What is the base pairing rule in DNA?

Back

In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).

Front

How does a chemical that prevents RNA formation affect protein synthesis?

Back

It disrupts protein synthesis because RNA is essential for translating the genetic code into proteins.

Front

What is the base sequence of the original DNA segment if the mRNA sequence is UGU CAA ACU CGA?

Back

The base sequence of the original DNA segment is ACA GTT TGA GCT.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid.
