Question

24-29 pleas help asap

and is used by 24) In the figure, "A" represents a the cell in__ a. sugar, glycogen b. amino acid, polypeptides c. phospholipid, cell membranes d. nucleotide, DNA 25) Meiosis I differs from mitosis in that: a. The chromosomes are intentionally broken during mitosis, but not meiosis b. Homologs are separated during melosis, but not mitosis Sister chromatids remain together at the end of mitosis d. Recombination occurs between chromosomes in mitosis e. 4 different products are generated at the end of meiosis L but 2 identical products are generated at the end of mitosis 26) Crossing over during meiosis results in: a. Changes in the order in which genes are present on the chromosome b. Changes in combinations of alleles on each chromosome c. Changes in the combinations of genes on each chromosome d.bandc cand d processine cell division in eukaryotes, a complete copy of the nuclear genome is sorted into two daughter nuclei via a med "mitosis". However, the mitochondrial genome doesn't undergo mitosis. How does the cell assure wete copy of the mitochondrial genome is present in each daughter celle ning each kinetochore to the microtubules, then pulling them apart of replication of the cell membrane, and then moving an origin to each end of the cell as the DNA that a complete copy of the mitocho b. Attaching the origin of replication of the is copied Mitochondrial chromosomes segregate at random, be and many mitochondria per cell usually each daughter cell gets severa d. Establishing tension (pulling each way then breaking the cohesinsapan e. New chloroplasts are generated in the cell they don't have to be inherited es segregate at random: because there are many copies of the genome per mitochondrion, 28) in the cell depicted here, each dark line represents a chromatid. The cell is in the following stage of the cell cycle: a start of DNA replication (S phase) b. prophase of meiosis c. anaphase of meiosis d. metaphase of mitosis 1 e. prophase of meiosis II 29) "Antennapedia" is a dominant mutant trait in fruit flies, and induces the conversion of antennae into forelegs. This trait is NOT X-linked. We cross two flies together, one of which displays the trait. We then take one normal female and her antennapedia brother from among their progeny, and cross them together. What is the expected ratio of phenotypes among their offspring? a. 50 wild-type : 50 mutant b. 75 wild-type : 25 mutant c. 25 wild-type : 75 mutant d. 100% wild-type e. It is impossible to say given the information provided.

its a carbon hydrogen chain

Answer 1

Answer 24:

The structure of A contains an amino group (NH3) and a carboxylic group (-COO).

This is the basic structure of any amino acid. Amino acids undero polymerization to form polypeptide.

Thus, correct choice should be:

b. Amino acid, polypeptide

Ans 25:

Difference between meiosis1 and mitosis :

b. Homologs are separated during meiosis I, but not mitosis

Ans 27: (c)

Ans 28: (c) anaphase of meiosis I
