Biology 207 - Midterm 1 || 100% Correct Answers.
n correct answers represents the number of chromosomes in a gamete
Haploid correct answers cells that only contain half the number of chromosomes (n)
Diploid correct answers cells that contain paired chromosome (2n)
c correct answers Describes the amount (content) of DNA in a haploid (gamete) cell
Genome correct answers The amount of genes in a haploid cell
Mitosis correct answers Cell division of diploid cells (2n) into diploid cells (2n)
Meiosis correct answers Cell division into diploid cells (2n) into haploid cells (n)
Fertilization correct answers Haploid cells (n) become diploid cells (2n)
Protected Cohesins correct answers Proteins that hold sister chromoitids together
Unprotected Cohesins correct answers Proteins that hold homologous chromosomes together
Spermatogenesis correct answers Meiosis in males
Oogenesis correct answers Meiosis in females
Zygote correct answers The conjunction of the sperm and the egg
, Dizygotic Twins correct answers Non-identical twins
Two eggs released and fertilized at the same time
Each embryo has a separate placenta and extraembryonic membrane (eventually fuse together)
Monozygotic Twins correct answers Identical Twins
Made by splitting at the 2 cell stage
The inner cell mass splits and the 2 embryos share a common extraembryonic membrane and
placenta
Budding correct answers Unequal cell division
Nucleic Acid Rules correct answers 1) Are made of triphosphate nucleotides
2) New nucleic acids are made using a ssDNA template
3) New strands of DNA are made in the 5' to 3' direction
4) dsDNA is pair antiparallel
5) Each nucleic base is paired with a complementary base
Telomerase correct answers Protein that recognizes a special sequence of nucleotides at the end
of the lagging strand and extends the parental strand using an RNA template in 5' to 3' direction
Nucleosome correct answers DNA + histone protiens
