Replication Transcription Translate

The sequence of DNA that serves as the attachment point for RNA polymerase is called what?

• promoter

• enhancer

• silencer

Which RNA carries the message?

• mRNA

• rRNA

• tRNA

The picture represents DNA replication, transcription, or translation?

• DNA replication

• Transcription

• Translation

The picture represents DNA replication, transcription, or translation?

• DNA replication

• Transcription

• Translation

Where in the cell does transcription take place?

• in the nucleus

• on ribosomes in the cell cytoplasm

• in the cytoplasm and mitochondria

• in the chloroplast

Answer explanation

Translation takes place on ribosomes in the cell cytoplasm, where mRNA is read and translated into the string of amino acid chains that make up the synthesized protein.

Translate the following mRNA strands into the appropriate amino acids

• mRNA: AGU ACU GCA

• Amino acids: Ser Thr Ala

• mRNA: CAU CAG UUC

• Amino acids: Met Arg Ile

• mRNA: AUG CCG AUA

• Amino acids: His Gln Phe

• mRNA: GAU GGC UGC

• Amino acids: Tyr Gly Tyr

• mRNA: UAC GGC UAU

• Amino acids: Asp Gly Cys

TRANSCRIBE the following sequence of DNA to mRNA: TAC CGA ATT

Using the chart with its abbreviated amino acid names, TRANSLATE the following sequence of mRNA: AUG GCU UAA

The picture represents DNA replication, transcription, or translation?

• DNA replication

• Transcription

• Translation

​ (a)   binds the nitrogen bases between the two strands of DNA.

• Hydrogen bond (H-bond)

• Phosphodiester bonds

• Glycoside bond

Answer explanation

There are three types of bond present in DNA:

Phosphodiester bonds exist between the nucleotides,

Hydrogen bond exists between the nitrogenous base,

Glycoside bond exists between the pentose sugar molecule and nitrogenous base.
