Gene
what type of bond holds nitrogen bases together ?
Hydrogen bonds
what is the monomer of DNA
Nucleotides
ACU is mRNA what is the anticodon ?
UGA
What are the parts of a nucleotide
Nitrogen base, sugar, phosphate group
what type of bonds hold amino acids together
peptide bond
The sequence of _____ determines the protein
Nucleotides
Function of DNA
stores information for building protein
Define- amino acid
Building block of protein
where does DNA replication take place
and the process
takes place in the nucleus
1. DNA unwinds
2. unzips
3. DNA Polymerase moves along the DNA strands attaching free floating nucleotides to the open strands
4. re zips
Compare and contrast DNA and RNA
DNA - doubled stranded, deoxyribose, thymine, template for individual
RNA- Single- stranded, ribose, Uracil, many different roles
transcribe DNA to RNA
AGC-CGA-TAC-GAC-TAG
UCG-GCU-AUG-CUG-AUC
what is the central dogma
DNA- RNA- protein
Function of DNA
stores an organisms genetic material in the nuclei
-replicates itself when dividing
-provides code or template for the particular sequencing of amino acids that bond together and make a protein
DEFINE CHROMOSOME-
threadlike structures made of DNA molecules that contain genes.
define nucleotide
Basic building block of DNA
DNA is a polymer consisting of monomers known as nucleotides
what does mRNA do during protein synthesis
serves as a template for RNA production
what is translation
cells use info from messenger RNA to produce proteins
What would happen in the mRNA is mutated during transcription
The final protein might not be functional
RNA structure
Base pairs- Adenine, Cytosine, Guanine, uracil.
contains ribose sugar
Single strand
DNA structure
Base pairs- Adenine, Thymine, Cytosine, Guanine
deoxyribose sugar
double helix
What is tRNA and what does it do?
Carries the amino acid to the ribosomes formed in the nucleus
What is a codon ?
Sequence of three nucleotides which together proteins form a unit of genetic codes in DNS or RNA
What are the bases found in DNA/RNA
DNA; ATCG
RNA; UAGC
