Imagine you are a student trying to decode the genetic code. An artificial mRNA molecule consisting of poly-CA (5ʹ... CACACACACA
Semmy [17]

Answer:

ACA: Threonine

CAC: Histidine

Explanation:

To answer this question we need to remember that the ribosome reads every three bases or 'codon' in order to assign the right tRNA carrying the amino acid.

In the first artificial mRNA we see two patterns of three letter:

CAC and ACA.

In the second artificial mRNA we are able to identify three different patterns:

CAA

AAC

ACA

And they repeat, so we end with three different polypeptides: polythreonine, polyglutamine and polyasparagine. This will depend on the initial letter the ribosome starts reading.

The only amino acid that repeats in both artificial mRNAs is Threonine,  and we see its pattern ACA also repeated.

So, we could assign this codon (ACA) to threonine.

We can then assume that the pattern CAC codifies for histidine since we only get this two polypeptides in the first mRNA.

Lastly with the information provided we cannot determine the codons AAC and CAA for glutamine or asparagine. We would need further experiments.

You have conducted an experiment using litterbags to assess the effect of lignin content on leaf decomposition rate. You selecte
BartSMP [9]

Answer:

B. The biomass of leaf litter in the bags will be greater in leaves with higher lignin content after the same length of time.

Explanation:

Lignin is a major, one of the most slowly decomposing components of dead vegetation, including leaf litters. The lignin content has been found to have a high correlation with litter decomposition.

<em>Hence, at the end of the experiment, the litter bag containing leaf litters with higher lignin contents will be expected to weigh more than those with lower lignin contents.</em>

The correct option is B.

If this flower has a normal chromosome number of thirty-eight, what is the number of chromosomes present in a sperm cell of this
Pepsi [2]
The number of chromosomes present in the haploid cells or gametes of this species, in this case sperm would be half the total genetic information in the plant's cells, in this case 1/2 of 38 which is 19.

The solution is B. 19.
