Genetics Study

Genetics study

Autosomal chromosome: Chromosomes other than sex chromosomes, in selfsame(a) pairs.
Sex Chromosomes: X and Y
Homologous: Chromosome pairs with same genes but may be expressed unalikely.

desoxyribonucleic acid: Deoxyribonucleic acid
Deoxyribose: Sugar
Acid: Phosphate
A nucleic acid, on with RNA.
Comprised of nucleotides, the structural units made up of sugar, phosphate and bases G, C, A, T (Guanine, Cytosine, Adenine, Thymine)
Carries our genic information.
RNA: Base pairs G, C, A, U (Uracil)
Single stranded
Lacks deoxy sugar
Transfers genetic mandate of DNA to ribosome outside nucleus. (DNA SAFE)

Gene: Distinct portion of DNA
Comprised of different based pairs that code for making proteins.
Basic units of inheritance
We have slightly 2500 genes.
A change in this base coding period is a mutation. (One of the pairs work overs switched, dropped, or repeated)

Chromosomes: Tightly packaged and coiled DNA.
DNA is coiled so that it is easier to write, transport and takes up less space. (Less fragile)
on that point are 23 pairs (46) of chromosomes in a somatic cell. (Diploid, 2n)
there are only 23 in a gamete.



(Ova/sperm, haploid, organise in gonads: ovaries/testes)

Proteins: Organic molecules that are polymers comprised of chemical building blocks called aminic acids, held by polypeptide bonds. They have roles in structure, transport, cellular functions and enzyme activity.

Genome: Complete copy of entire set of human gene instructions.

Meiosis and Mitosis likeness:
Mitosis produces 2 diploid daughter cells, identical to parent. Meiosis produces 4 haploid daughter cells.
Mitosis involves Interphase (chromosomes visible), Prophase (chromosomes double and intersect at kinetochore as chromatids), Metaphase (chromosomes line up along equator), Anaphase (each half of chromosome pairs break down towards either end of cell) either end, Telophase (nuclear envelopes form) and Cytokinesis (division). Meiosis involves Interphase, Prophase I, Metaphase I, Anaphase...If you want to get a full essay, order it on our website: Ordercustompaper.com
