More questions RNA/ DNA

Question 1

Transcription

Answer 1

Transcription is when DNA is copied to make a template for RNA

Question 2

Translation

Answer 2

mRNA & tRNA meet @ ribosome where amino acid chain is formed

Question 3

Helicase

Answer 3

Unzips the genes to allow for the strands to seporate

Question 4

Polymerase

Answer 4

assembles the correct nucleotide to each strand of the original DNA

Question 5

Ligase

Answer 5

Glue that connects the old and new strands together to finalize the copy of DNA

Question 6

Describe what semi-conservative means in terms of DNA

Answer 6

When DNA is replicated halk is old and half is new

Question 7

Why is transcription important?

Answer 7

It’s important because mRNA can leave the nucleus with the copied DNA while DNA has to stay.

Question 8

What role does RNA polymerase play in transcription?

Answer 8

unwinds original DNA strand and connects new mRNA strand to make the copy of the message

Question 9

Diffrence between mRNA tRNA rRNA

Answer 9

mRNA- carries code from DNA to ribosomes
tRNA- brings the amino acids to the mRNA strand and pairs up with the opposite codons
rRNA- allows a location for mRNA to deliver message and tRNA to deliver the amino acids and make the protein chain

Question 10

Translation importance

Answer 10

Its important because everything that has a job in the body/ cell uses proteins

Question 11

Where does translation take place in the cell?

Answer 11

ribosome

Question 12

what is a codon?

Answer 12

sequence of 3 nucleotides which code for amino acids to make a protein
