What are some functions of noncoding DNA?
Artyom0805 [142]

Answer:

Explanation:

The non-coding DNA sequences forms the part of the organism's DNA. It is the part of the human genome which does not encode for any protein sequence. Some of the non-coding DNA may be transcribed into into any of the functional non-coding RNA molecules such as ribosomal RNA, transfer RNA and regulatory RNA. Other functions of the non-coding DNA involve translational and transcriptional regulation of the protein coding sequences, origin of DNA replication process, scaffold attachment, telomeres and centromeres.

A researcher claims that a newly discovered microorganism is an autotroph. Which observation would support his claim?
Maslowich

Answer:

The microorganism creates its own energy.

Explanation:

Based on the pattern of nutrition, a living organism can either be autotrophic or heterotrophic. Autotrophic organisms are those organisms capable of synthesizing its own food or energy source using light (photosynthesis) or chemicals (chemosynthesis). Heterotrophs, on the other hand, cannot synthesize their own food, hence, they depend on other organisms for energy.

According to this question, a researcher claims that a newly discovered microorganism is an autotroph. For this claim to be true, this means that the microorganism must be capable of CREATING ITS OWN FOOD/ENERGY either by photosynthesis (light) or chemosynthesis (inorganic chemicals).

When one allele is dominant to another, what is the most common biological mechanism for this dominance?
MAVERICK [17]

Answer:

A. Dominant alleles often encode functional products, whereas recessive alleles often do not encode functional products

Explanation:

One gene can have it's variant forms called allele but in one individual only two allele form of a gene can be present. These two allele form can be the same(homozygous) or different(heterozygous). A dominant allele often encode a function protein of product while recessive allele often code for non- functional product.

Therefore when the dominant allele is present in the chromosome then function products are formed which can be seen in the phenotype and even a single dominant allele produce the functional product like in heterozygous condition so phenotype in heterozygous and homozygous dominant condition appears same. So the correct answer is A.
