Quiz On DNA Structure and Replication

Question 1

What is translation

Answer 1

Amino acids are linked together at the ribosome to form the protein encoded by the mRNA.

Question 2

mRNA

Answer 2

carries genetic information transcribed from DNA in a linear form reads in sets of 3 nucleotide sequences called codons

Question 3

tRNA

Answer 3

deciphers codons in mRNA

each amino acid has its own subset of tRNAs, which bind the amino acid and carry it to the growing end of the polypeptide contains anticodon that base-pairs with the complementary codon in mRNA

Question 4

What is Transcription

Answer 4

In the nucleus, the gene is rewritten into a single stranded primary RNA transcript using one strand of DNA as a template. The enzyme RNA polymerase catalyzes this process.

Question 5

What is a codon

Answer 5

a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule.
