Unit 4 - Nucleic Acids and Gene Expression

Front

What enzyme is responsible for adding nucleotides during DNA replication?

Back

DNA Polymerase

Front

What is the process of copying DNA to make RNA called?

Back

Transcription

Front

What is the structure of DNA?

Back

A double helix composed of two strands of nucleotides.

Front

What is the central dogma of molecular biology?

Back

DNA -> RNA -> Protein

Front

What is the role of RNA in protein synthesis?

Back

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

Front

What are the main differences between DNA and RNA?

Back

DNA is double-stranded, contains Thymine, and is found in the nucleus; RNA is single-stranded, contains Uracil, and can be found in the nucleus and cytoplasm.

Front

What is the function of ribosomes in the cell?

Back

Ribosomes are the sites of protein synthesis.

Front

What is the significance of Rosalind Franklin's photo 51?

Back

It provided critical evidence for the double helix structure of DNA.

Front

What is the process of DNA replication?

Back

The process by which a DNA molecule makes a copy of itself.

Front

What is a codon?

Back

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