List three main differences between RNA and DNA

The sugar in RNA is ribose and the sugar in DNA is deoxyribose
RNA is generally single-stranded while DNA is double-stranded
RNA contains you were so in the place of thymine

1

What is one job in which most RNA molecules are involved

Protein synthesis

2

What is the function of the messenger RNA

Carries copies of the instructions for assembling amino acids from DNA to the rest of the cell

3

What is the function of a ribosomal RNA

Proteins are assembled on ribosomes. Ribosomes are made up of several dozen proteins as well as ribosomal RNA

4

What is the function of transfer RNA

Transfers each amino acid to the ribosome to help assemble proteins

5

During transcription, DNA polymerase

Binds to RNA and separates the DNA strands

6

I already put Gracies is one strand of

DNA as a template to assemble nucleotides into a strand of RNA

7

Many RNA molecules from eukaryotic genes have sections, called ________ edited out of them before they become functional

Introns

8

The remaining pieces, called________ are spliced together

Exons

9

What are two explanations for why some are in a molecules are cut and spliced

To produce several different forms of RNA

Small changes in DNA sequences could have dramatic effects in gene expression

10

Proteins are made by joining_______ into long chains called polypeptides

Amino acids

11

How can for bases in RNA carry instructions for 20 different amino acids

The genetic code is read three letters at a time so that each word of the coded message is three bases long

12

What is a codon

Consists of three consecutive nucleotides that specify a single amino acid that is to be added to the polypeptide

13

How many possible three base codons are there?

64

14

Is the following sentence true or false? All amino acids are specified by only one codon

False

15

What is the code on the combination that serves as the start codon for protein synthesis

AUG

16

What occurs during the process of translation

The cell uses information from messenger RNA to produce proteins

17

Where does translation take place

Cytoplasm

18

Before translation occurs...

Messenger RNA is transcribed from DNA in the nucleus

19

Is the job of transfer RNA to bring the proper amino acid into

The ribosomes to be attached to the growing peptide chain

20

What is an anti-codon

Each tRNA molecule has three unpaired bases called anti-codon are complimentary to one mRNA codon

21

MasterPlan

DNA

22

Blueprint

RNA

23

Remains in the nucleus

DNA

24

Goes to the ribosomes in the cytoplasm

RNA

25

Many proteins are _____ Which catalyze and regulate chemic reactions

Enzymes

26

Is the following sentence true or false? Jeans are the keys to almost everything that living cells do.

True
