What is a point mutation?

Back

A point mutation is a type of mutation that involves the substitution of a single DNA base with a different base.

Front

What are the main differences between RNA and DNA?

Back

RNA contains uracil instead of thymine and has ribose sugar instead of deoxyribose.

How is the DNA sequence GCTATA transcribed to mRNA?

Back

The DNA sequence GCTATA is transcribed to mRNA as CGAUAU.

Front

What is a chromosomal deletion?

Back

A chromosomal deletion is a type of chromosomal mutation where a segment of the chromosome is lost.

Front

How many codons are needed to code for one amino acid?

Back

One codon is needed to code for one amino acid.

Front

What is the role of codons in protein synthesis?

Back

Codons are sequences of three nucleotides in mRNA that specify a particular amino acid during protein synthesis.

Front

What is the function of uracil in RNA?

Back

Uracil replaces thymine in RNA and pairs with adenine during transcription.

Front

What is the significance of ribose in RNA?

Back

Ribose is the sugar component of RNA, which distinguishes it from DNA that contains deoxyribose.

Front

What are the types of mutations that can occur in DNA?

Back

The main types of mutations include point mutations, insertions, deletions, and chromosomal mutations.

Front

What is the process of transcription?

Back

Transcription is the process by which the DNA sequence of a gene is copied into mRNA.
