Mutations and Protein Synthesis

Front

What is the main function of tRNA?

Back

The main function of tRNA is to bring amino acids from the cytoplasm to the ribosomes.

Front

What is a deletion mutation?

Back

A deletion mutation is a type of mutation where one or more nucleotides are removed from the DNA sequence.

Front

What amino acid is represented by the codon UUA?

Back

The codon UUA represents the amino acid Leucine.

Front

What are the results of mutations?

Back

Mutations can result in changes in DNA sequence, genetic variation in a species, and differing amino acid sequences.

Front

What types of effects can genetic mutations have?

Back

Genetic mutations can be beneficial, harmful, or neutral.

Front

Define mutation in the context of genetics.

Back

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

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into amino acid sequences.

Front

What is the difference between a point mutation and a frameshift mutation?

Back

A point mutation involves a change in a single nucleotide, while a frameshift mutation involves the insertion or deletion of nucleotides that shifts the reading frame.

Front

What is the significance of the genetic code?

Back

The genetic code is a set of rules that defines how the sequence of nucleotides in DNA is translated into the amino acid sequence of proteins.

Front

What is transcription in protein synthesis?

Back

Transcription is the process of copying a segment of DNA into mRNA, which then carries the genetic information to the ribosome.
