"You can't have one without the others". how can you relate this your body system?

Two black guinea pigs were mated and over several

years produced 29 black and 9 white offspring.Explain these results, giving the genotypes of parents

and progeny.

Construct an ‘enlarged cell’ map on an 8.5” x 11” o r 11” x 14” sheet of paper (one

side only!!). You must draw t he entire process of t ranscription and t ranslation l inking

the terms (below) with arrows a nd connecting words (n o sentences please! ). Maps

should be neat and attractive. You may add more t erms i f you wish, but you must use a t

least all of t he f ollowing:

5’ cap, spliceosomes, non-coding DNA strand, poly A t ail, ribosomes (large and

small subunits), precursor-mRNA, exons, i ntrons, start codon (AUG), RNA

Polymerase, promoter (TATA box), mRNA, TAC (on DNA strand), polypeptide, t RNA

with anticodon (be specific), amino acids (be specific), release f actor

Note:

A patient comes into your clinic with unexplained paralysis in her limbs. She has no history of neuromuscular problems. After further questioning you find that that she had taken a drug “X.” Explain the effect of a possible toxin in the drug on actin filaments that might be the cause of her paralysis.

Name two similarities and two differences between the cellular processes of importing protein into the ER and importing protein to the nucleus.

Explain the role of the Endoplasmic Reticulum in protein folding. Consider quality control, the solutions to folding and refolding, and the degradation of proteins.

what are the building blocks of lipids

Using an example, explain why it is necessary to determine the genotypes of the gametes of the mated individuals in order to predict the phenotypes of their offspring.

Transgenic technology have disadvantages like allergic reaction, emergence of super pests and loss of biodiversity. So how we can prevent or overcome this issues?
