Difference between RNA and DNA Each nucleotide contains a different ribose

Difference between rna and dna each nucleotide

This preview shows page 12 - 25 out of 36 pages.

Difference between RNA and DNA: Each nucleotide contains a different _______ : ribose instead of deoxyribose. Bases are A, G, C, and U (uracyl, not thymine) A pairs with U; G pairs with C

RNA RNA is ___________ stranded and shorter RNA is __________ stable than DNA: RNA doesn’t persist in the cell for long (sometimes it exists for a few seconds), whereas DNA can persist for the life of the cell.

CENTRAL DOGMA DNA ________ Proteins 3 different RNA molecules involved in protein synthesis: M______________ RNA (mRNA) R______________ RNA (rRNA) T______________ RNA (tRNA) transcription translation
Image of page 15
Transcription: DNA RNA TRANSCRIPTION: RNA synthesis from DNA. T___________: making an RNA copy, called m______________ RNA (mRNA), of a small part of the DNA molecule.

Transcription: DNA RNA Transcription occurs in the N_____________ mRNA carries the message about what type of protein to make from the DNA in the nucleus to the ribosome The nucleotide sequences of RNA and DNA are the same (except in RNA uracil is used instead of thymine) mRNA is synthesized from DNA using base pairing DNA unwinds in a section

T______________ of RNA from a template strand of DNA RNA polymerase attaches at the promoter sequence of DNA, and it moves along the DNA, unzipping the strands – this allows for one mRNA molecule to be formed.

During _____________, a molecule of messenger RNA is formed as a complementary copy of a region on one strand of the DNA molecule
Image of page 19
Transcription Once mRNA is formed, enzymes in the nucleus remove the i__________ (non-coding regions) and leave the exons (expressed segments)

The Genetic Code Each 3 consecutive bases on the mRNA is a code word, codon, that specifies an amino acid. The genetic code consists of ______ codons, (4x4x4), but only 61 code amino acids. Three codons act as signal terminators ( UAA, UAG, UGA ) One codon, AUG , codes for methionine, and is also the _________ signal for translation.

The Genetic Code The G__________ Code – every ______ nucleotides on mRNA codes for a particular amino acid (3 at a time) Code is universal – true for all organisms!

20 Amino Acids There are _____ amino acids – they are like the ‘bricks’, or building blocks to make all proteins
