Substitution

Front

During which phase of mitosis do the spindle fibers split the centromere and chromatids move to opposite sides?

Back

Anaphase

Front

What type of molecule is represented by the sequence CGAUCGAUCAAG?

Back

This is a segment of RNA.

Front

What amino acid is represented by the codon AGG?

Back

Arginine

Front

What two molecules form the sides (backbone) of the DNA ladder?

Back

Deoxyribose sugar and phosphate.

Front

What is the role of mRNA in protein synthesis?

Back

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

Front

What is the function of ribosomes in the cell?

Back

Ribosomes are the sites of protein synthesis, where amino acids are assembled into proteins.

Front

What is the process of transcription?

Back

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

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What are the three types of RNA and their functions?

Back

mRNA (messenger RNA) carries genetic information, tRNA (transfer RNA) brings amino acids to ribosomes, and rRNA (ribosomal RNA) makes up the ribosome.
