Strucute of Dna and Dna Flashcards
Whats a Karyotype
a photograph of your chromosomes arranged in pairs from longest to smallest. Sex chromosomes are last.
what are haploids
Sex cells are called haploids.
The Possession of one copy of each chromosome in a cell. Haploids cells in humans are found in the sperm or egg
what are diploids
Have two chromsomes they are body cells not sex cells so they can be found throughout ur body tissue
What is the shape of Dna
Double Helix. Dna is made of two linked strands that wind around each other forming a spiral ladder
What is a nucleotide
A nucleotide is a molecule consisting of one sugar, one phosphate and one nitrogenous base.
what is a nucleotide made up of
one sugar, one phosphate and one nitrogenous base
What makes the rungs of Dna Ladder?
Nitrogenious bases, cytosine , guanine, Thymine Adenine
What are the four differtn types of nitrogenious bases
ADENINE , THYMINE CYTOSINE GUANINE
what is the complimentary base paring rule
Cytosine pairs with Guanine
Thymine pairs with Adenine
What does Rna Stand for
ribonucleic acid
what is Rna
Rna is a type of nucleic acid that contains ribose sugar and is single stranded.
what are the rna bases
adenine
Cytosine
Guanine
Uracil
Does Rna stay in the nucleus or exist the nucleus
Rna exits the nucleus while dna stays in the nucleus
what is triplet
A sequence of three nucleotides in Dna that can code for an animino acid
