Biology
What is RNA?
Ribonucleic acid is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes.
What is deletion?
A type of genetic change that involves the absence of a segment of DNA.
What is DNA?
A self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
What is a Chromatid?
A chromatid is one of the two identical halves of a chromosome that has been replicated in preparation for cell division.
What is a blackhole made of?
Black holes are made of matter packed so tightly that gravity overwhelms all other forces.
What are Homologous chromosomes?
Homologous Chromosomes are made of chromosomal pairs of the same length and centromere positions for the genes corresponding to the same loci.
What is Insertion?
A type of genetic change that involves the addition of a segment of DNA.
What is traslation?
the process by which a sequence of nucleotide triplets in a messenger RNA molecule gives rise to a specific sequence of amino acids during synthesis of a polypeptide or protein.
What is transcription?
Transcription is the process of copying a segment of DNA into RNA.
What is an atom?
the basic unit of a chemical element.
How many phases are in Mitosis?
There are 4 Phases.
What is Subsitution?
a type of mutation in which one nucleotide is replaced by a different nucleotide.
What is a Codon?
What is an Allele?
One of two or more DNA sequences occurring at a particular gene locus.
How is Plasma made?
A plasma is created when one or more electrons are torn free from an atom.
What is a Diploid Cell?
A cell containing two copies of each chromosome.
What is a Chomasome?
A structure found inside the nucleus of a cell.
What is a Phenotype?
an observable trait
What is a Gamete?
A gamete is a reproductive cell of an animal or plant.
What is Anaerobic Fermentation?
Anaerobic fermentation is a metabolic process done by bacteria and eukaryotes in the absence of air to convert carbohydrates into the products like gases, alcohol, and acids.
What is a Haploid Cell?
Haploid refers to the presence of a single set of chromosomes in an organism's cells.
What is Crossing Over?
The exchange of DNA between paired homologous chromosomes (one from each parent) that occurs during the development of egg and sperm cells (meiosis).
What is the genetic makeup of an individual called?
Genotype
What would you call an organism that shows the recessive phenotype?
homozygous recessive
