Answer:

Stephen is not his biological father.

Explanation:

DNA fingerprinting is a technique use to determine the DNA sequence of an individual organism. Short tandem repeats are unique among the individuals ans used to identify the individual in population.

The George DNA fingerprinting shows that he has STRs length of 6 and 7. Stephen's STRs does not match with his son George whereas Mary shows some similarities with George STRs. This indicates that Stephen is not the biological father of George because the biological father's STRs must match with the children STRs.

Thus, the correct answer is option (a).

Answer:

A protein-coding gene has an open reading frame (ORF) that make easier its identification

Explanation:

During translation, the messenger RNA (mRNA) is read by the ribosomes as triplets of nucleotides called codons in the open reading frame (ORF). An ORF can be defined as a gene fragment composed of codons which are translated into amino acids in a polypeptide chain. According to the genetic code, the information encoded by these codons will specify the sequence of amino acids in the protein, as well as the start codon and stop codons of the protein-coding genes. A start codon (AUG) is a site at which translation into protein begins, while stop codons (UAA, UAG, and UGA) mark the site at which translation ends. Moreover, non-coding RNAs (ncRNAs) don't have ORFs because they do not encode for proteins, and therefore their identification is more difficult.

What change could a student measure to collect data about the rate of photosynthesis in a certain type of algae when it is expos
Alborosie

Answer:

A student can measure the number of gas bubbles given off by the algae.

Explanation:

  • Photosynthesis is the process where green plants convert light energy into the fuel energy for their development and activities.
  • Algae is also involved in the photosynthesis process, so the it releases the gas bubbles.
  • The oxygen emission process is done by secreting the bubbles by green plants during photosynthesis process.
  • So to know about the  photosynthesis rate the number gas bubbles, really helps a lot.
