Protein Synthesis Flashcard

Front

What describes an mRNA strand being transcribed?

Back

The mRNA strand is complementary to the DNA template strand. Uracil instead of thymine is paired with adenine.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the purpose of transcription in protein synthesis?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which carries the genetic information to the ribosome for protein synthesis.

Front

How are differences in traits determined in DNA?

Back

Differences in traits are determined by the sequence of nucleotides in the DNA.

Front

How do nitrogenous bases influence protein synthesis?

Back

The order of nitrogenous bases determines the order of amino acids in the proteins synthesized.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the role of mRNA in protein synthesis?

Back

mRNA serves as a template for translating the genetic code into a sequence of amino acids, forming a protein.

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 instead of thymine.

Front

What is translation in the context of protein synthesis?

Back

Translation is the process where ribosomes read the mRNA sequence and assemble amino acids into a polypeptide chain to form a protein.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular machinery that facilitate the translation of mRNA into proteins by linking amino acids together.
