Document Summary

Exerts its affects by carrying information by which cells can produce proteins through transcription and translation. Translation: trna and rrna use the information on the mrna to align amino acids into the primary structure of a protein. Transcription: information on dna gene is used to make a molecule of mrna the basic structure of the protein is encoded in the dna genes. Transcription the mrna is a long single strand of nucleotides (agcu= bases) sugar= ribose the size of the mrna depends on the size of the gene (small gene= small mrna) Only one strand of dna is used to make mrna this is called the template strand. The mrna that is formed is complementary to the template strand of. In the process of dna replication the important enzyme was dna polymerase; in mrna synthesis the important enzyme= rna polymerase the. Rna polymerase is responsible for manufacturing mrna by using the dna template strand.

Where are mRNAâs synthesized in eukaryotes?

If the bold term in each statement is correct hen write the letter C next to it. if the term is incorrect then replace it with the correct term.

The nucleotide bases found only in RNA and not in DNA is thymine.

The class of RNA molecules that carries the amino acids that are added to the growing polypeptide chain is tRNA.

During translation immediately after the first and second tRNA molecules become attached side by side on the mRNA., a hydrogen bond is formed between adjacent amino acids.

In the genetic code, 20 bases on the DNA code for a single amino acid.

The major lipid involved is transcription is RNA polymerase.

The one strand of DNA used as a template in the making of mRNA during transcription, is the template strand.

1. A region of a chromosome contains two strands of DNA, yet only one is used to transcribe a gene because

A. all genes are found on the same strand of DNA in a chromosome.

B.both strands are transcribed, but only one strand of DNA contains a reading frame.

C.RNA polymerase binds to the terminator, stopping transcription on one strand of DNA.

D.RNA polymerase binds to the promoter, which precedes the gene only on the template strand of DNA.

E.the start of transcription is random along the chromosome and doesn't always occur on a gene.

2. In eukaryotes an mRNA molecule can only be translated by one ribosome at a time.

True or False

3.The process by which cells use the information of RNA molecules to make proteins is transcription.

True or False
