Unit 8 retest

Front

What is the correct sequence of events in protein synthesis?

Back

DNA → mRNA → Protein

Front

What type of mutation is represented in the DNA sequence TACGGCACT TACGGAAC?

Back

Insertion

Front

What is the mRNA sequence transcribed from the DNA sequence TACGCCGTIGTA?

Back

mRNA: AUGCGGCAAUGA; Amino Acids: Methionine, Arginine, Glutamine, Stop

Front

What process involves the synthesis of mRNA from a DNA template?

Back

Transcription

Front

How is gene expression regulated?

Back

By cell differentiation and environmental factors.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the sites where translation occurs, synthesizing proteins by linking amino acids together.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of making mRNA from DNA, while translation is the process of synthesizing proteins from mRNA.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein structure and function.
