DNA

Question 0

M RNA

Answer 0

Messenger RNA is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression.

Question 1

RNA

Answer 1

ribonucleic acid, a nucleic acid present in all living cells.

Question 2

R RNA

Answer 2

In molecular biology, Ribosomal ribonucleic acid is the RNA component of the ribosome, and is essential for protein synthesis in all living organisms.

Question 3

TRNA

Answer 3

It helps transfers amino acids. It uses codons to know what amino acids to bring

Question 4

Uracil

Answer 4

a compound found in living tissue as a constituent base of RNA. In DNA its place is taken by thymine.

Question 5

Ribose

Answer 5

a sugar of the pentose class that occurs widely in nature as a constituent of nucleosides and several vitamins and enzymes.

Question 6

Replication

Answer 6

the action of copying or reproducing something.

Question 7

Replication fork

Answer 7

DNA replication is the process of producing two identical replicas from one original DNA molecule.

Question 8

Helicase

Answer 8

Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. They unzip the DNA and RNA

Question 9

Polymerase

Answer 9

an enzyme that brings about the formation of a particular polymer, DNA or RNA.

Question 10

Protein synthesis

Answer 10

Protein biosynthesis is the process by which biological cells generate new proteins.

Question 11

Codon

Answer 11

a sequence of three nucleotides that together form a unit of genetic code in a DNA or RNA molecule.

Question 12

Termination signal

Answer 12

Tells when RNA needs to stop or when you need to stop reading.

Question 13

Intron

Answer 13

The message from the messenger RNA that is entering

Question 14

Answer 14

They are a 1 carbon ring.

Question 15

Nucleotide

Answer 15

Made up of a phosphate and a sugar.

Question 16

Semi-conservative

Answer 16

It is used in DNA replication you are taking half of an old DNA and and get half new DNA

Question 17

Universal code

Answer 17

DNA found in every living thing.

Question 18

Transcription

Answer 18

Taking a copy of DNA this is done by the mRNA

Question 19

Lygase

Answer 19

That glue that holds the exons together

Question 20

Peptide bonds

Answer 20

It hold the codons together

Question 21

Polypeptide

Answer 21

It is many things but is know as proteins

Question 22

Point mutation

Answer 22

A translating DNA that has one base it’s an error

Question 23

Frameshift

Answer 23

Changes the amino acids sequence beyond it

Question 24

Deletion

Answer 24

A base is lost

Question 25

Insertion

Answer 25

An extra base is added

Question 26

Substitution

Answer 26

One base is substituted for another

Question 27

Operator

Answer 27

In genetics, an operator is a segment of DNA to which a transcription factor protein binds.

Question 28

Mutation

Answer 28

A change in or the process of changing, e.g. nature, form or quality.

Question 29

Mutagen

Answer 29

Any agent (physical or environmental) that can induce a genetic mutation or can increase the rate of mutation.
