What is a haploid cell? - ANSWER - A cell that contains one set of chromosomes
What is a diploid cell? - ANSWER - A cell that contains two sets of chromosomes
What is chromatin? - ANSWER - The substance of which eukaryotic chromosomes
are composed, consisting of mostly proteins, DNA, and RNA.
What is a centriole? - ANSWER - a cylindrical organelle near the nucleus in animal
cells, occurring in pairs and involved in the development of spindle fibers in cell
division.
What is a chromosome? - ANSWER - A structure carrying genes is a linear
sequence, found in the nucleus, consisting of DNA and protein.
What is DNA? - ANSWER - A double-stranded, helical nucleic acid molecule capable
of replicating and determining the inherited structure of a cell's proteins. It makes up
the genetic material of most living organisms and plays a role in determining
heredity.
What is RNA? - ANSWER - A single-stranded nucleic acid molecule involved in
protein synthesis. It is responsible for carrying the genetic code transcribed for DNA
to specialized sites within the cell where the information is translated into protein
composition.
What is a nucleotide? - ANSWER - A nucleotide is the basic building block of nucleic
acids. RNA and DNA are polymers made of long chains of nucleotides. A nucleotide
consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached
to a phosphate group and a nitrogen-containing base.
What is transcription? - ANSWER - Transcription is the process by which the
information in a strand of DNA is copied into a new molecule of messenger RNA
(mRNA). ... This complex initiates transcription, and the RNA polymerase begins
mRNA synthesis by matching complementary bases to the original DNA strand.
What is translation? - ANSWER - Translation is the process by which a protein is
synthesized from the information contained in a molecule of messenger RNA
(mRNA). Translation occurs in a structure called the ribosome, which is a factory for
the synthesis of proteins
What is endocytosis and exocytosis? - ANSWER - Endocytosis is the process of
capturing a substance or particle from outside the cell by engulfing it with the cell
membrane, and bringing it into the cell. Exocytosis describes the process of vesicles
