Transcription

Front

What is the main difference between RNA and DNA?

Back

RNA contains uracil and ribose, while DNA contains thymine and deoxyribose.

Front

What part of a nucleotide is responsible for genetic variation?

Back

The nitrogenous base.

Front

How is the DNA sequence GCTATA transcribed to mRNA?

Back

It is transcribed to CGAUAU.

Front

If one strand of DNA has the sequence TTACCG, what is the sequence of the complementary strand?

Back

The complementary strand is AATGGC.

Front

Where does transcription occur in a cell?

Back

Transcription takes place in the nucleus.

Front

What are the three main types of RNA?

Back

mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).

Front

What is the role of mRNA in transcription?

Back

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

Front

What is the function of tRNA during translation?

Back

tRNA transports amino acids to the ribosome and matches them to the coded mRNA message.

Front

What is a nucleotide composed of?

Back

A nucleotide consists of a phosphate group, a sugar (ribose or deoxyribose), and a nitrogenous base.

Front

What is the significance of the nitrogenous base in nucleotides?

Back

The nitrogenous base determines the genetic code and the information carried by the DNA or RNA.
