8.3 and 8.4

Choose the nucleotide sequence of the RNA strand that would be complementary to the following DNA strand: GTAGTCA.

CAUCAGU

When new DNA molecules are formed, almost all errors are detected and fixed by

DNA polymerase

The central dogma of molecular biology states that information flows in one direction from a. nuclei to RNA to cytoplasm.

DNA to RNA to protein

Which of the following events occurs directly after a DNA molecule is unzipped?

Free-floating nucleotides pair up with exposed bases

Which of the following events occurs directly after RNA polymerase recognizes the transcription start site of a gene?

The DNA strand begins to unwind, separating the two strands

What are the main functions of DNA polymerase

binds nucleotides and corrects base pair errors

The main function of tRNA is to

bring amino acids from the cytoplasm to the ribosomes

A primary difference between transcription and replication is that transcription

happens repeatedly throughout a single cell cycle.

The process of making new DNA molecules is semiconservative. This means that every new DNA molecule is composed of

one original and one new strand of DNA.

The process that makes an exact copy of a cell's DNA is called

replication
