Work in a small group or alone to solve this "mating mystery." Then answer the questions that follow. Mister Poppleton, a cat enthusiast who breeds cats and competes on the Cat Fancier's Association competitiveshow circuit, has just received quite a shock! His award-winning cat, Emeline, has given birth to some surprising kit-tens. Of her five kittens, four have black fur, and one has an unexpected coat of fur that is a patchwork of black andorange, known as a tortoiseshell pattern. Mister Poppleton was breeding Emeline with an award-winning male cat, named Barnaby, but he is now worriedthat Emeline may have been having secret sexual relations with a neighborhood stray cat, named Hugo. Mister Pop-pleton consults with his veterinarian, Dr. Doolittle, for some expert advice. Dr. Doolittle explains: In cats, there are several genes that determine fur color. One of those genes is found onthe X chromosome and codes for whether a cat has orange fur or black fur. Because it is a sex-linked gene, it isexpressed a bit differently in males than in females. In males:.If a male cat has the orange allele on his X chromosome, he will have orange fur. If a male cat has the black allele on his X chromosome, he will have black fur. In females:.If a female cat has the orange allele on both of her X chromosomes, she will have orange fur. If a female cat has the black allele on both of her X chromosomes, she will have black fur. If a female cat has the orange allele on one of her X chromosomes and the black allele on the other X chro-mosome, she will have a tortoiseshell coat.

your the dumbest b**tch ive ever seen

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

the cell cycle is the final answer! : )

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
