Q

Termination: Step 3 in translation

A

this is when the tRNA runs into the stop codon: UAA, UAG, UGA (none are amino acids). The ribosome attaches the last amino acid that will serve as the protein and it will be sent to the cytoplasm to undegro modification. Lastly, the ribosome breaks of the mRNA starnd.

Q

Initiation: S1 in protein synthesis

A

Enzyme called RNA polymerase binds to promoter (an area in the DNA) this signals the DNA to unwinds so that the enzyme can read its strands. RNA polymerase will make an mRNA strand.

Q

Order of DNA replication

A
  • Helicase begins to break the hydrogen binds between nitrogen bases
  • Free floating nucleotide pair up with the exposed nitrogen bases
  • DNA polymerase attach the free floating nucleotides to the exposed nitrogen bases
  • Two molecules of DNA are created
  • Cell starts into the mitosis parts of the cell

24
Q

what are the 2 steps of protein synthesis

A

Initiation and Translation

25
DNA
Deoxyribonucleic acid
26
Initiation
the subunit of ribosome attaches to the 5 end of the RNA strand. in which the subunit reads the nucleotides in the mRNA in the groups of 3 (amino acids) until it reads AUG (methionine). After it reads this codon its recruits as large ribosomal subunit and tRNA (transfer RNA) it contains an area called anti codon which is complementary to the mRNA strand. tRNA also carries a specific amino acid.
27
organelle that makes up the protein
ribosome
28
---- uses DNA template to make an RNA or mRNA
transcription
29
the main template for protein synthesis is the ---
DNA
30
What are the 3 steps of translation/
initiation Elongation Termination
31
what do you call the 2 stages of protein synthesis
transcription and translation
32
Elongation: step 2 in translation
the complete ribosome with its large and small units travels along the mRNA and reads the codons. tRNAs matches the aniti codons to their respective codons. An amino acid is made coming out of the ribosome. elongation starts from 5 end of the mRNA to the 3 end.
33
Transfer DNA
a small RNA molecule that helps translate genetic information into proteins
34
how many nucleotides
4
35
tRNA uses ---- to match the mRNA
anticodons
36
the process of making proteins in a cell
protein synthesis
37
if we are made in the same quantity of nucleotides in DNA and RNA as well as amino acids in proteins, why are we different?
bc the fundamental blocks mentioned are not arranged in the same order
38
tRNA is used in the ---- of proteins
translation
39
Messenger RNA
a single stranded molecule that carries genetic info from DNA to the cytoplasm of the cell
40
what is the 3 pattern of information that occurs most frequently within our cell
DNA Replication transcription Translation
41
the --- can move out the nucleus
RNA
42
Ribosomal RNA
non-coding RNA that's a key part of ribosomes, which are cell structures that make proteins.
43
The process of ----- converts DNA into ----
Transcription and mRNA
44
Elongation: Step 2 of Protein synthesis
Nucleotides are added to the created mRNA strand. RNA polymerase will read the unwound DNA and continues to build the mRNA molecule using complementary base pairs
45
a biomolecule
Nucleic acid
