What does DNA stands for?

deoxyribonucleic acid

The two men who discovered the DNA structure

waston and crick

Name the three parts of nuclectide

sugar, phosphate, nitrogenous base

Adenine always bonds with?

thymine in DNA

What does Guanine bond with in DNA?

cytosine

What is the shape of the DNA molecule?

a double helix

DNA replication

making an exact copy of DNA

What does RNA stand for?

Ribonucleic acid

How is RNA different than DNA?

uses ribose, single strand, uses uracil

Three types of RNA?

MRNA, TRNA, RRNA

TRNA

transfer RNA

MRNA

messager RNA

RRNA

ribosomal RNA

Transcription

process that transfers the genetic code from DNA to RNA

Which type of RNA carries the amino acid to the ribsomoe?

TRNA

Which type of RNA contains the genetic information to make protein?

MRNA

Can DNA leave the nuclues?

No, but RNA can leave

What RNA makes up the structure of the ribosome and helps to join together the other 2 types of RNA?

RRNA

Codon

sequence of 3 nucleotides on a TRNA that matches a specific amino acid in protein synthesis.

What molecule has a codon?

MRNA

What is an anti codon?

A sequence of three nucleotides in tRNA that pairs with a complementary codon in mRNA during protein synthesis.

What molecule has an anti codon?

TRNA

What codon starts translation?

AUG

Translation

process join mRNA to tRNA and carries an AA to the ribosome to form the actual protein

Where is the actual protein made in the cell?

in the ribosomes
