When would be a good time in San Francisco to collect seashells? Explain your answer.
snow_tiger [21]

Answer:

12th May at 4.17 PM

Explanation:

This is because this is during the low tides and the low tide is at its lowest, at -0.7, m than any other date or time of the month. This means that most of the shoreline has receded deep into the ocean and exposed most of the continental shelf than any other time. This leaves rooms for more sea shells to be exposed and easily collected.

The phase of cell division in which chromatin condenses into chromosomes is ____ A. anaphase B. metaphase C. prophase D. telopha
Lady_Fox [76]

Answer:

C (Prophase)

Explanation:

All cells undergo division in order to produce more daughter cells. Cell division occurs immediately after the interphase, which is a resting and preparatory phase for mitosis or cell division. Prior to cell division, the DNA is found to be coiled around histone proteins to form a structure called CHROMATIN. The process of cell division occurs in four phases; Prophase, Metaphase, Anaphase, and Telophase.

In the Prophase stage, which is the first stage of mitosis, this Chromatin begins to condense or becomes compact by undergoing further coiling into a visible X-shaped structure called CHROMOSOME. This shape of the chromosome is as a result of the replication into sister chromatids that occurred in the S-phase of interphase.

During translation, nucleotide base triplets (codons) in mRNA are read in sequence in the 5’ → 3’ direction along the mRNA. Amin
Paladinen [302]

Answer:

The question is incomplete, it lacks the mRNA sequence. The sequence is as follows:

5′−AUGGCAAGAAAA−3′

The answer is Met-Ala-Arg-Lys

Explanation:

Gene expression in living organisms involves the process of transcription and translation. Transcription is the synthesis of a complementary strand of mRNA from a DNA template while translation involves using the transcibed mRNA as a template to synthesize amino acid sequence (proteins).

In the RIBOSOME, where the synthesis of protein occurs, the mRNA nuceleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies a particular amino acid. The collection of all codons is the genetic code. Hence, for a specific mRNA sequence that reads 5′−AUGGCAAGAAAA−3′. The nucleotides will be read three at a time starting with AUG which is a codon that encodes METHIONINE.

Next, GCA is a codon that encodes ALANINE

Next, AGA is a codon that encodes ARGININE

Finally, AAA is a codon that encodes LYSINE.

Hence, the amino acid sequence using the above mRNA sequence, will read: Met-Ala-Arg-Lys
