Question 231 pts
The first phase of the Cell Cycle is the G2 phase.
True |
False |
1. false
because polygenic trait is determined by multiple genes. As the name indicates polygenic means poly genes.
2. true.
Both genotypes have dominant allele A that is why the expression of allele A appears.
i is recessive on A.
152. true.
colour blindness and haemophilia both are sex linked recessive traits. These traits appears only when both alleles appears in recessive form.
161: false
transcription is the process for the formation of RNA from DNA. the sequence of DNA is recognized by RNA polymerase and complementary sequence of ribonucleotides are formed which is known as RNA.
171. false:
the reproductive cells are known as germ cells. normal cells of body is known as somatic cells.
181.
True: Asexually reproducing organisms are able to transfer their characters into offsprings. but a sexual reproduction occurs by the involvement of only single parent. so single parent transfer all the characters to offspring in asexual reproduction.
191.
true
diploid cells have two copies of every gene and have complete genetic information in the genetic sets.
201: false
meiosis is a reduction division in which haploid cells are produced from deployed parental cell. in the process of Mitosis diploid cells are produced from diploid parental cell.
meiosis occurs in germ cells and gametes.
mitosis occurs in somatic cells.
211. false. Gametes are haploid cells produced by reductional division of chromosomes known as meiosis.
221.
True: cell divide and fulfill all the requirement by doing metabolic activities.
231.
false.
the first phase of cell cycle is G0 phase.
G0 phase then G1 phase then synthetic or S phase then G2 phase then M phase.

my assigned organism is Naked mole rat (Heterocephalus glaber). please type it. The first step in understanding how information is passed from one generation to the next is understanding how cells divide, particularly how the DNA is passed on to the resulting cells. In this discussion, you will describe the life cycle of an animal or plant of your choosing. The animal or plant you choose must have a sexual life cycle (although it may also have an asexual life...
4. A man makes 0 units of an enzyme due to homozygous recessive gene on chromosome 21. He marries a woman who produces 100 units of the same enzyme due to the heterozygous pairs of genes on her chromosomes 21. Their firstborn son has three copies of chromosome 21 and produces 200 units of the enzyme mentioned above. a) In which parent did the nondisjunction occur? b) Did the nondisjunction occur in meiosis I, meiosis II or mitosis? c) What...
