What process is nucleus involved in?

Transcription

New cards
2

How is the nucleus involved in Protein Synthesis?

Where is DNA is transcribed

New cards
3

What process is mRNA involved in?

both

New cards
4

How is mRNA involved in Protein Synthesis?

mRNA is produced from DNA in transcription. mRNA is then transcribed into amino acids

New cards
5

What process is the ribosome involved in?

translation

New cards
6

How is the ribosome involved in Protein Synthesis?

where mRNA is translated to amino acids

New cards
7

What process is tRNA involved in?

translation

New cards
8

How is tRNA involved in Protein Synthesis?

the link between mRNA and the chain of amino acids

New cards
9

How is DNA involved in Protein Synthesis?

The original code that is translated and transcribed

New cards
10

What process is the cytoplasm involved in?

Translation

New cards
11

How is the cytoplasm involved in Protein Synthesis?

where translation occurs

New cards
12

What is an intron?

DNA that codes for nothing

New cards
13

What is an exon?

DNA that contains important information

New cards
14

Do introns or exons exit the nucleus to move onto translation?

Exons

New cards
15

DNA traits

sugar = deoxyribose

phosphates present = yes

letters of nitrogen bases = A,T,C,G

complementary base pairs = A-T, C-G

number of strands = 2

New cards
16

RNA traits

sugar = ribose

phosphates present = yes

letters of nitrogen bases = A,U,C,G

complementary base pairs = A-U, C-G

number of strands = 1

New cards
17

What process is DNA involved in?

transcription

New cards
18

What is the difference between codons and anticodons?

Codon - 3 letter nucleotide sequence on mRNA that codes for an amino acid

Anticodon - 3 letter nucleotide sequence on tRNA that binds to and “reads” a specific mRNA sequence

New cards
19

What is the role of mRNA during protein synthesis?

complements DNA, travels from nucleus to cytoplasm and directs synthesis of protein, !!!codes for amino acids!!!

New cards
20

What is the role of rRNA during protein synthesis?

binds with proteins to make ribosomes

New cards
21

What is the role of tRNA during protein synthesis?

transports amino acids that match the mRNA code to the ribosome

New cards
22

What is point mutation/substitution?

one letter gets switched (1 potential different amino acid)

New cards
23

What is insertion?

one letter gets added to the code, all amino acids after the mutation are changed

New cards
24

What is deletion?

one letter gets removed from the code, all amino acids after the mutation are changed
