Answer:

For 1st chart

human/chimp =  no differences

human/gorilla = no differences

human/rhesus monkey = 1 difference

human/horse = 1 difference

human/kangaroo = 1 difference

For 2nd chart

human/chimp =  no differences

human/gorilla = 1 difference

human/rhesus monkey = 1 difference

human/horse = 4 differences

human/kangaroo = 5 differences

Explanation:

1. The chimps sequence is closest to the humans, and the kangaroo is the one farthest away. The chimps sequence had the least amount of differences, and the kangaroo had the most.

2. This is true. Species are always evolving into a new and more adapted species which also affects their genes.

A situation in which the coefficient of coincidence is greater than 1.0 would indicate that: A. no double crossovers were found
damaskus [11]

Answer:

B. there were more double crossovers in the progeny than would be expected based on probability

Explanation:

Crossing over or recombination can be defined as the exchange of genetic material between homologous chromosomes during meiosis. Moreover, the coefficient of coincidence is the number of double recombinants found in the progeny. The coefficient of coincidence can be estimated by the following equation:  

Coefficient of coincidence  (COC) = ADRF / EDRF

where ADRF = Actual Double Recombinant Frequency

and  EDRF = Expected Double Recombinant Frequency

In the case above described, ADFR is higher than EDRF, and therefore COC will be higher than 1.

In a certain mutant strain of bacteria, the enzyme leucyl-tRNA synthetase mistakenly attaches isoleucine to leucyl-tRNA 10% of t
Effectus [21]

Answer:

The correct answer is "proteins in which isoleucine is inserted at some positions normally occupied by leucine".

Explanation:

The missing options of this question are:

A. proteins in which leucine is inserted at some positions normally occupied by isoleucine.

B. proteins in which isoleucine is inserted at some positions normally occupied by leucine.

C. no abnormal proteins, because the ribosomal translation machinery will recognize the inappropriately activated tRNAs and exclude them from the translation process.

D. no proteins, because the inappropriately activated tRNAs will block translation

The correct answer is option B. "proteins in which isoleucine is inserted at some positions normally occupied by leucine".

In normal conditions, the enzyme leucyl-tRNA synthetase attaches one leucine amino acid to leucyl-tRNA as part of synthesis of proteins that have one or more leucine residues in their sequences. Since the enzyme of this mutant strain of bacteria mistakenly attaches isoleucine to leucyl-tRNA 10% of the time, approximately 10% of all the proteins that normally have leucine residues will going to have isoleucine. Therefore, These bacteria will synthesize proteins in which isoleucine is inserted at some positions normally occupied by leucine.

Is it a or d? <br> B and c don’t make sense to me
Arlecino [84]

Answer:

D. An observation is based on evidence, an inference is not.

Explanation:

When you infer something, you're basically guessing at it, while an observation is something that you can see and prove.
