Biology Quiz Flashcards
Mitosis and Meiosis are Examples of…
cell division
Mitosis is only used for sexual reproduction
false
Meiosis is only used for sexual reproduction
true
Mitosis goes from 1 cell to…
2 cells
Meiosis goes from 1 cell to…
4 cells
Order fo the phases of mitosis
Prophase Metaphase Anaphase Telophase
3 characteristicts of genes
reproduce themselves, passed down to the next generation, found in nuclear material
3 characteristicts of chromosomes
produce RNA, tightly coiled, consist of many genes
What are 3 functions of genes
causes a specific trait, produce a particular chain of amino acids (produce protiens), control the activation and deactivation of protein coding genes
What are the 3 functions of chromosomes
contain genes, duplicate for cell division, seperate during cell division
what is a zygote
a diploid cell formed by joining 2 haploid gametes
what is a gamete
haploid cells that unite to form a zygote
what is fertilization
The process of forming a zygote, the union of gametes
some comparisons between mitosis and meiosis
both make new cells, both deal with cell division
diferences between mitosis and meiosis
Mitosis makes two daughter cells while Meiosis makes four, Mitosis is asexual while Meiosis is sexual, In Mitosis daughter cells are identical to the parent cell while in Meiosis they aren’t, Mitosis are diploid while Meiosis are haploid
differences between Sexual and Asexual reproduction
sexual requires the joining of 2 haploid gametes while asexual does not, sexual has haploid cells while asexual has diploid cells
similarities between Asexual and Sexual reproduction
both are types of reproduction, both lead to the formation of new things
3 characteristics of codons
series of 3 nucleotides, found in both DNA and RNA, contains start and stop codons
3 functions of codons
used to specify an amino acid, instruct cells to create needed proteins, form the basis of cell communication
3 characteristics of DNA
contains sugars, contains a phosphate, contains bases, double helix, double stranded, contains the code of life, bases are bounded by hydrogen bonds
3 functions of DNA
stores information, synthesises proteins, contains cellular instructions, helps construct RNA
homozygous
both traits were the same
heterozygous
the traits received were different
3 characteristics of RNA
becomes a copy of DNA during transcription, contain proper series of codons, they are a component of ribosomes, it is single stranded
3 functions of RNA
serves as a temporary copy of DNA, produced during transcriptions, serves as structural components of ribosomes
