Which statement regarding DNA packing in eukaryotes is false?

Biology
1 answer:
nekit [7.7K]3 years ago
8 0

Answer:

The correct answer is - A. Tight DNA packing tends to promote gene expression.

Explanation:

Euchromatin which is less packed or condensed is highly expressed as it participates in the transcription whereas highly compacted chromatin - heterochromatin not expressed at all as these does undergoes the transcription process.

DNA binds around a core of 8 subunits of Histone protein in a nucleosome in which DNA is negatively charged and histone protein is positively charged protein .

DNA packing decreases its transcription and hence no expression.

How do fossils and fossil records support the idea that life change over time? How is the fossil age measured?
Alex Ar [27]

Fossils, or preserved parts of organisms from the distant past, have shown that species change over time. Radiometric dating can be used to determine the age of fossils by measuring the how much of the radioactive materials in each rock layer have broken down.

yarga [219]

Answer:Algae contributes to the phosphorus cycle

Explanation:Algae are organisms which have distinct chlorophyll and are autotrophic in nature .Most of them live in water.Algae include the Unicellular chlamydomanas and the multicellular sea weed.some algae are colonial and some are filamentuous.Algae possess chlorophyll, carotenoids and phycobillins as pigments.

Algae are important primary producers in the water bodies and produces a significant portion of oxygen.

Some algae eg diatoms are fossilized due to their glass cell wall and are known as diatomaceous earth, which has various uses such as abrasives,tooth paste and as filters.

Red algae produces calcium carbonate which forms coral reefs.

The products of some algae are used as solid gels and source of agar for microorganism culture.

What is true about translation? Choose ALL that apply.
Licemer1 [7]

<u>In the process of translation, the statement stands correct and applies are as follows:</u>

  • The ribosome has two sub-units that work together.
  • Amino acids are joined by peptide bonds.
  • Each tRNA brings in exactly one amino acid that corresponds to the anti-codon.
  • The order of the amino acids is determined by the mRNA which is transcribed from DNA.

Answer: Options A, B, C, and E

<u>Explanation:</u>

In the process of translation, ribosomes are the structural unit where the translation is being performed and it has the two sub-units which enact together the translational process.

Any two amino acids are bonded together by peptide bond and tRNA brings one amino acid at a time which corresponds to the anti codon. The order of amino acids is determined by mRNA transcribed from the DNA, and not from the ribosome. Thereby, all given options are correct except the option D.
