Q

What Is Dna needed for but why can’t it do it

A

It is needed to make protein in the ribosomes of the cell

A

To be able to make protein a copy of dna which is smaller is made

Q

What is the base u full name and why is it used in transcription

A

Because there is no T in mRNA so the base Uraci is made to attach to A

Q

Explain the three steps to transcription

A

1 dna unzips so the two strands are separated and one of the strands acts as a template
2 complimentary bases attach to the strands being copied and forms a strand of mRNA
3 when completed mRNA detaches from DNA and DNA zips up again

Q

What happens after transcription

A

The mRNA is small enough to move out of the nucleus and then travels to the ribosomes in the cytoplasm where protein is made

Q

Why does the order of amino acids matter when making protein

A

Because each different combination makes a different protein

Q

Name the three main steps of translation

A

1mRNA attaches to a ribosome and the nucleotide sequence is interpreted and new protein is made
2 the ribosome reads the nucleotides on the mRNA in codons and each codon codes for a specific amino acid
3 the amino acids then join in a chain to make a protein
