Structure of DNA
The shape of a DNA molecule, which looks like a twisted ladder.
What is a double helix?
Transcription creates working copies of this?
What is DNA?
The mRNA produced during transcription is "read" by these.
What are the ribosomes?
The phase of the cell cycle where cells spend most of their life.
What is interphase?
Meiosis produces four daughter cells and is used to produce these?
What are gametes?
What are nucleotides?
This is where transcription takes place.
What is the nucleus?
Sets of three nucleotides in a row that code for about twenty different amino acids.
What are codons?
The process where each new daughter cell produced will have the same number and kinds of genes as those in the original parent cell.
What is mitosis?
Meiosis involves two cell divisions and results in this kind of daughter cells that only have one set of genes (n).
What is haploid?
This base always pairs with guanine.
What is cytosine?
This type of RNA is produced during transcription.
What is messenger RNA (mRNA)?
The molecules used to build proteins.
What are amino acids?
Chromosomes are lined up at the center of the cell in this phase of mitosis.
What is metaphase?
What is fertilization?
Each section of a DNA molecule that codes for a unique protein.
What is a gene?
This temporarily "unzips" part of the DNA molecule in order to "read" the gene.
What is an enzyme?
Amino acids are carried to the ribosome by this type of RNA.
What is transfer RNA (tRNA)?
In this phase new chromosomes reach opposite ends of the cell and uncoil.
What is telophase?
The diploid cell that results from fertilization.
What is a zygote?
Each nucleotide consists of a phosphate, a base, and this.
What is a sugar?
This base is used in place of thymine in mRNA.
What is uracil?
The process of amino acids being bonded together in a growing chain.
What is protein synthesis?
Sister chromatids divide into separate chromosomes in this phase of mitosis.
What is anaphase?
Each chromosome in a diploid cell has a matching partner with the same genes on it. These matching pairs of chromosomes are called this.
What are homologous chromosomes?
