pretest DNA and protein synthesis

Front

What nucleotide base does RNA contain that DNA does not?

Back

Uracil (U)

Front

What is the complementary DNA sequence for the base sequence TTGACTAGG?

Back

AACTGATCC

Front

What is a chromosome mutation known as deletion?

Back

A deletion mutation is when a part of the chromosome is lost, e.g., ABCDEFG → ABCDEF.

Front

What are the components of the backbone of DNA?

Back

Sugar and phosphate units.

Front

What is the main function of tRNA?

Back

To bring amino acids from the cytoplasm to the ribosomes.

Front

What are the four nucleotide bases found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

Front

What is the role of mRNA in protein synthesis?

Back

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

Front

What is the process of transcription?

Back

Transcription is the process of copying a segment of DNA into RNA.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.
