Question

Which of the following bases would a nucleotide contain if it were paired to a nucleotide containing thymine? adenine uracil thymine cytosine guanine How many codons are in the following sequence of nucleotides: AAAUGCUCGUAA? 1 3 4 6 12 A codon is a type of DNA repair enzyme. a promoter that prevents the attachment of RNA polymerase. a sequence of three nitrogenous bases on mRNA that corresponds to an amino acid. the part of the ribosome to which mRNA attaches. a sequence of three nitrogenous bases on tRNA that corresponds to an amino acid. Match the processes with the types of cell division: mitosis meiosis binary fission Production of eggs from oocyte mother cell Allows blood cells to multiply Produces sperms from spermatogonium mother cell Allows bacterial cells to multiply Takes place in cancer cells A sexually reproducing organism has 12 chromosomes in each somatic cell, how many chromosomes would you expect to find in the organism's gametes (sperm/egg)? 4 6 10 12 The number of chromosomes in the human white blood cell (WBC) is 48 46 47 23 The exchange of genes between pairs of homologous chromosomes is called. crossing over linkage group genetic linkage crossing back Which of the following is not the purpose of meiosis? to produce gametes to reduce chromosome number to permit genetic mixing of parental genes to produce identical daughter cells Crossing over results in genetic recombination by reducing the original cell's chromosomes number in half randomly separating the maternal and paternal chromosomes mixing half the maternal chromosomes with half the paternal chromosomes permitting the exchange of genetic material between maternal and paternal chromosome Which is NOT a typical site for the occurrence of meiosis? plant ovary plant root cells human testis human ovary plant anther What is the product of translation? nucleotides DNA ribosomes RNA polypeptide chain The genetic code is universal in all organisms is based on 64 codons made of sequences of three nucleotides is redundant, i.e., each amino acid has more than one codon all of the above How many different types of RNA codons are there? 3 5 12 64 128 Meiosis: keeps the chromosome number constant from generation to generation ensures that all daughter cells have the diploid number of chromosomes occurs when cells are cloned All of the choices are correct The sketch below depicts a cell from an organism in which 2n = 2 and each chromosome is metacentric, Which is the correct stage of division for this cell in this sketch. Anaphase of mitosis Anaphase of meiosis I Anaphase of meiosis III Telephase of mitosis Somatic cell from a woman with Down syndrome has 47 autosomes and 2 X chromosomes 45 autosomes and 1 X and Y chromosome

Explanation / Answer

22. A.adenine

23. C.4

24. C. The the sequence of three nitrogenous bases present on mRNA that correspond to an aminoacid.

25. Meiosis

26.mitosis.

27.meiosis

28. Binary fission

29. Mitosis.

Note. Adinine pair with thymine and vice versa where as guanine with cytosine and vice versa.

AAA, UGC,UGC, UAA ThereFore four codon present in the following sequence of nucleotide. The three nucleotide combines and form one codon. These codon are present on mRNA which codes for amino acid wehen anticodon on tRNA come and pair with them tRNA bring aminoacid for these codon sequence.

Mitosis is asexual reproduction while meiosis is sexual reproduction in which gamete are produced by the mother cell which is diploid and daughter cell are haploid where as in mitosis the daughter cell are diploid and it help in growth of the body, somatic growth, make everything other than sex cell or germ cell, but bacteria form of cellular division is through binary fission in which one cell divide into two.
