Molecular Biology Processes and Functions

Front

What is the central dogma of molecular biology?

Back

DNA is transcribed into RNA, which is translated into protein.

Front

What are codons?

Back

A sequence of three nucleotides.

Front

How do replication, transcription, and translation connect to evolution and gene regulation?

Back

They provide genetic variation and control gene expression.

Front

What is the role of RNA polymerase during initiation in transcription?

Back

To bind to the DNA promoter region and start RNA synthesis.

Front

Which type of RNA carries the genetic code from DNA to ribosomes?

Back

mRNA.

Front

What is the function of tRNA in protein synthesis?

Back

tRNA transports amino acids to the ribosome for protein assembly.

Front

Define transcription in molecular biology.

Back

Transcription is the process of copying a segment of DNA into RNA.

Front

What is the function of ribosomes in translation?

Back

Ribosomes facilitate the assembly of amino acids into proteins based on mRNA sequences.

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.

Front

What is a promoter in the context of gene expression?

Back

A promoter is a DNA sequence that initiates transcription of a particular gene.
